ASTM 305 stainless steel plate in 2025 is priced lower than premium nickel-rich grades but higher than basic austenitic alternatives, with typical spot ranges for standard plate from roughly $1,000 to $2,200 per metric ton in Chinese export listings and notable regional variation driven by nickel/scrap movements, alloy surcharges, tariffs, and local demand patterns. Sellers in North America are seeing materially different effective prices because of alloy surcharges and trade measures compared with Europe and Asia.
what is ASTM 305?
We treat ASTM 305 (UNS S30500) as an austenitic chromium-nickel stainless steel that was developed to give improved formability and lower work-hardening than conventional 304 in multi-stage drawing operations. It retains corrosion resistance similar to 304 while having a slightly raised nickel content that moderates strain hardening and improves deep-draw performance. For plate forms, this makes 305 useful where extensive forming is required or where the part geometry demands multiple cold forming stages.
Chemical and mechanical profile
-
Typical composition (summary): chromium ~17–19%, nickel ~9–12%, balance iron with small traces of manganese, silicon, carbon controlled to low levels. The elevated nickel fraction when compared with 201/430-series grades is the main cost driver because nickel is the pricier raw input.
-
Mechanical behavior: moderate tensile strength, good elongation and very low rate of work hardening. This reduced work hardening reduces intermediate anneals in complex forming processes, improving manufacturing yields — a value proposition that sometimes offsets the higher alloy cost.
-
Price relevance: when nickel or nickel-bearing scrap prices climb, grades with even modest extra nickel (like 305) see levy effects via surcharges and spot market premiums. Likewise, if scrap inflows ease and nickel weakens, those premiums compress.
Typical product forms, thickness ranges and commercial specifications
We commonly supply 305 in the following forms for plate markets:
-
Plate/sheet: common thicknesses for plate used in industry range from 1.0 mm up to 60 mm depending on the application and the ordering standard (plates for pressure vessel vs. general fabrication). ASTM A240 is the typical standard that covers many stainless plate grades for general applications; 305 plate is produced to that or equivalent national standards.
-
Coil and strip: thinner gauges for deep drawing (coils and slit strip) are usual for 305 because its low work hardening is advantageous for progressive stamping lines.
-
Surface finishes: bright annealed, 2B cold-rolled, annealed and pickled finishes are commonly offered. Surface finish choice can add to processing cost.
Key market drivers that determine 305 plate pricing in 2025
Below we list and explain the principal forces that set 305 plate prices this year.
4.1 Raw material and alloy surcharge
Nickel metal and stainless scrap prices are the primary inputs. Producers use monthly alloy surcharge formulas to pass nickel fluctuation through to buyers. Surcharges remain a crucial component of final price and have shown volatility in 2025. Suppliers publish surcharge tables and update them frequently.
4.2 Regional trade measures and tariffs
Trade policy — including tariffs, quotas and antidumping measures — materially shifts landed cost. For example, U.S. market pricing behaves differently because tariff shields and trade remedies alter the competitive landscape and create pockets of higher or lower effective cost. European markets have experienced import pressure that compresses local mill margins and affects domestic list prices. Recent market commentary has emphasised these regional differences in 2025.
4.3 Mill capacity and producer behavior
When mills reduce planned expansions or delay investments, available primary production tightens. Conversely, increased exports from low-cost regions (notably parts of Asia) flood markets, pushing merchant prices down. Both dynamics have shown influence in 2025.
4.4 Energy, logistics and seasonal demand
Energy (for melting and hot rolling), port congestion, freight rates and seasonal demand patterns (construction and appliance manufacturing cycles) all alter effective unit cost and lead time.
4.5 Product form, size and finishing
Custom thicknesses, heavy plate, special surface finishes, and tight-tolerance cut parts carry premiums versus standard mill stock. For deep-draw sheet, coil processing and slitting add process fees that increase the per-ton price.
2025 market snapshot — what the numbers say
Market data in 2025 shows a mixed picture: Chinese online supplier listings frequently show export offers for 305 sheet and plate in the band of about $1,000–$2,200 per metric ton depending on thickness, MOQ and finish. These are indicative catalog/market prices from trading and factory sellers, not guaranteed transaction prices.
Industry commentary and mill reporting in 2025 indicate that U.S. and European regions do not always move in tandem with Chinese export offers. For instance, reported U.S. steel price indices and some HRC benchmarks show notable year-to-date movements, while European reference prices have been pressured downward because of import volumes. This creates regionally different effective plate prices and shifting margins for service centers.
Important buyer note: online listing prices are useful price signals but should be validated with live supplier quotations that include incoterm, thickness, finish, MOQ, certification and delivery window. We always recommend requesting a landed price that lists each surcharge and freight component.

| North America (effective landed) | $800 – $1,200 / short ton (reference HRC index ~ $876/short ton reported). | U.S. figures need unit conversion and account for surcharges and tariffs. |
| Japan / Korea | $1,200 – $2,300 / t (est.) | Prices influenced by regional demand and domestic mill contracts. |
Table methodology note: China supplier listings and B2B marketplaces provide visible ask ranges; journalistic reporting and mill indices provide regional benchmarks. We used these signals to form the indicative ranges above; specific purchase prices will vary by contract terms and date.
How we at luokaiwei (MWalloys) quote ASTM 305 plate — our transparent approach
When we price 305 plate for an overseas buyer we itemize costs and drivers in this order:
-
Base mill or factory price — determined by gauge, width, and finish.
-
Alloy surcharge — passed through monthly or per-shipment based on a published formula linked to LME nickel and domestic scrap indices. We record the surcharge calculation in the proforma.
-
Processing fees — cutting, levelling, special edge treatment and inspection.
-
Quality documentation — mill test reports (MTR), PMI / spectro reports if requested, and third-party inspection charges.
-
Packing, export fees and freight — containerization, FCL/LCL options and port handling.
-
Taxes, duties and local import fees — we calculate landed cost per incoterm.
-
Profit and buffer — transparent margin shown on the quotation.
We supply a line-item proforma. Buyers can then request adjustments (e.g., delivery to a bonded warehouse, CIF/DDP options, or factory inspection windows). We also offer variable MOQ arrangements for long-term customers.
Logistics, lead time and hidden cost items buyers must check
-
Lead time: depends on stock or new production. Factory stock dispatch may be 1–3 weeks; custom plate orders or heavy thickness may require 6–12 weeks.
-
Freight variations: container space scarcity or surcharges can add weeks and hundreds of dollars per ton.
-
Inspection & acceptance: if the buyer requires third-party inspection, allocate time and budget.
-
Surcharges & currency: ask for the currency of the quote and the date the alloy surcharge is fixed. Many suppliers will lock surcharge for only a short window.
Quality, testing and certifications to insist upon
When you purchase ASTM 305 plate, insist on:
-
Mill Test Report (MTR) showing chemical composition and mechanical test results to ASTM A240 or equivalent standard.
-
Traceability documentation that ties the MTR to the plate heat number.
-
Surface inspection and dimensional reports for critical parts.
-
Non-destructive testing (NDT) where required by application (dye penetrant, ultrasonic).
-
Third-party inspection for high-value or safety-critical orders.
We maintain a checklist for buyers and include it in our quotations so that no test or certification item is missed.

FAQs
Q1 — Is 305 basically the same as 304?
A: No. Both are austenitic and corrosion performance is comparable, but 305 has a slightly higher nickel content and lower work hardening rate, providing superior formability for multi-stage forming.
Q2 — How much more does 305 cost than 304?
A: The premium varies with nickel and scrap levels. When nickel surges, 305 will generally carry a modest premium over 304 because of its higher nickel fraction. Market premiums can range from a few percent to a larger band depending on the month. For numeric context, public Chinese export listing bands for 305 sheet/plate in 2025 fall in ranges we cited earlier.
Q3 — Are there additional fees a buyer should expect beyond the mill price?
A: Yes. Expect alloy surcharges, cutting/processing fees, freight, export handling, inspection charges and any import duties. We always provide a line-by-line proforma so these are transparent.
Q4 — How does the choice of incoterm affect final price?
A: Strongly. EXW leaves freight and customs risks to the buyer and usually shows a lower base price. CIF or DDP shifts risk to the seller and raises the price because the seller absorbs freight, insurance and often customs handling.
Q5 — Is now a good time to buy (calendar 2025)?
A: That depends on contract horizon and tolerance for price movement. Market commentary in 2025 shows regionally divergent pricing and active surcharge resets; for users needing security, negotiating a medium-term contract with regular review points or a small hedged volume can reduce exposure to sharp monthly swings.
