321 Thick Stainless Steel 4*8 2b/hl/no.1/ Sheet And Plate

Ti is added in the 321 stainless steel as a stable element, so it is better than 316 stainless steel under high temperature. 321 stainless steel owns good wear resistance and corrosion resistance in both organic acids and inorganic acids at different temperature and concentration, especially in...

Description

Type 321 is made of titanium and has corrosion resistance. It can be repeatedly exposed to 800 °F. It is a stable stainless steel plate. Its main advantage is excellent resistance to crystal growth after exposure to temperature. The inter-corrosion is in the range of chromium carbide precipitation, from 800 to 1 SOO'F (427 to 8160 ° C). The 321 plate was stabilized by the addition of titanium to prevent the formation of chromium carbide. The 321 stainless steel plate cannot be hardened by heat treatment and can only be processed by cold working. It can be easily welded and machined through standard workshop manufacturing practices.
