Import 321 Stainless Steel Plate, 4541 Stainless Steel — Buy in Bulk from Supplier in China

Xinhairunda Steel Co., Ltd. supplies 321 stainless steel plate, a titanium-stabilised austenitic grade designated 1.4541 under EN standards, from their base at Aodu Steel Market in Tianjin. The listing details plate dimensions spanning 0.5 mm to 30 mm thickness, with widths of 735 mm to 1800 mm and lengths up to 6000 mm, all sold in bundles with a 1 tonne minimum order. The material conforms to GB, JIS, ASTM, AISI and EN standards, with 321 specifically selected for its resistance to intergranular corrosion in the 425-850 degrees C sensitisation range.

The 321 grade contains a minimum 5 x (C%) titanium addition, typically 0.4-0.7 percent Ti, which forms stable titanium carbides and prevents chromium depletion at grain boundaries. The plates are hot-rolled and annealed as standard, with surface finishes ranging from No.1 (hot-rolled, annealed and pickled) to 2B (cold-rolled, annealed, pickled, skin-passed). Typical mechanical properties for solution-annealed 321 plate include 205 MPa minimum yield strength, 515 MPa minimum tensile strength, and 40 percent minimum elongation in 50 mm. The文理enrichment: standard mill edge or trimmed edge supply; typical thickness tolerance +/-0.3 mm for plates under 4 mm, +/-0.5 mm for 4-25 mm, per ASTM A480/A480M.

Buyers of 321 plate from this Tianjin distributor span petrochemical, aerospace, power generation and pharmaceutical sectors, where welded components must survive thermal cycling without sensitisation. Common applications include expansion bellows, furnace components, aircraft exhaust manifolds, and chemical processing equipment. The supplier notes capability to manufacture non-standard dimensions and accessories on request. Third-party inspection is offered, though the buyer should specify the required inspection body and test protocol when ordering. All stated dimensions require confirmation against mill test certificates, as the listing presents illustrative stock sizes rather than a live inventory.

Xinhairunda Steel Co., Ltd. operates from Aodu Steel Market in Tianjin, a major steel distribution hub in northern China with direct port access via Tianjin Port. The supplier's tier is marked as imported, indicating they handle mill-direct or import-traded material rather than manufacturing from raw melt. The trust tier is harbour, and the response rate shows 0.00 with zero average response hours, meaning the buyer should expect to follow up actively by phone or alternative channels rather than relying on platform messaging.

The company profile states they are a special steel distributor engaged in stainless steel plates and tubes, with claimed experience across biotechnology, pharmaceutical, electronic engineering, food machinery, petrochemical, chemical, metallurgy, refrigeration, paper, aerospace, water conservancy and power industries. They offer non-standard product manufacture and accessories per user needs. No verified factory ownership, ISO certification status, annual turnover, employee count, or specific client names are provided in the source data, and none should be assumed.
