At Piyush Steel, we specialize in providing high-quality Stainless Steel 321 Sheets & Plates, known for their exceptional resistance to intergranular corrosion, even in harsh thermal conditions. These products adhere to stringent standards, including ASTM A240, ASME SA240, and DIN 1.4541. The UNS number for this alloy is S32100. SS 321 is an austenitic stainless steel enriched with a titanium stabilizer, which enhances its resistance to carbide precipitation at high temperatures and ensures its structural integrity in high-stress environments. We also provide other grades such as 321H, 304, 304L, 316 and many more.
Table Of Content
The chemical composition of 321 stainless steel sheet and plate includes 17-19% chromium, 9-12% nickel, 0.7-1.2% titanium, and small amounts of other elements like manganese, silicon, and carbon. This specific composition imparts excellent corrosion resistance and maintains the alloy's mechanical properties under a wide range of temperatures. The tensile strength of this material typically reaches 515 MPa, with a yield strength of 205 MPa, and it has a hardness of approximately 95 HRB. These properties make 321 stainless plates and sheets suitable for aerospace, chemical processing, and thermal processing equipment applications.
Our 321 stainless steel plate and sheet products are available in various thicknesses and dimensions to meet diverse application requirements. Commonly produced thicknesses for sheets range from 0.5mm to 6mm, while plates are available in thicknesses from 6mm up to 100mm. Standard sizes include 1000mm x 2000mm, 1220mm x 2440mm, and 1500mm x 3000mm, though we can accommodate custom dimensions upon request. The versatility in size and thickness options allows these materials to be used in various structural, manufacturing, and industrial applications.
The ss 321 plate price in Mumbai typically varies between INR 300 to 500 per kilogram, depending on factors such as thickness, size, and market dynamics.
