SMM Industries LLP is a trusted name for providing high-performance Stainless Steel 321 Plates that meet demanding industrial requirements across the globe. These plates are titanium-stabilized austenitic stainless steel products designed to resist intergranular corrosion and deliver excellent strength at elevated temperatures. Stainless Steel 321 Plates are an upgraded version of 304 stainless steel, improved with titanium for stabilization, which makes them ideal for applications involving continuous exposure to high temperatures ranging from 427°C to 816°C.

What are Stainless Steel 321 Plates?

SA240 TP321 specifications, ensuring precise chemical composition and reliable mechanical properties. These plates are globally known by designations such as UNS S32100 and WNR 1.4541, and in different standards they may be referred to as X6CrNiTi18-10 in the European EN standard, SUS 321 in Japan’s JIS standard, Z6CNT18-10 under AFNOR (France), and 321S31 in the British Standard. The presence of titanium in these plates helps prevent the formation of chromium carbides during welding, which otherwise leads to intergranular corrosion. This property makes them highly durable and capable of performing in aggressive chemical and thermal conditions.
