Product Description
A213 TP321 UNS S32100 BRIGHT ANNEALED STAINLESS STEEL SEAMLESS TUBE
Overview
TP321 is a stable stainless steel. Its main advantage is that it has excellent resistance to intergranular corrosion after exposure to the chromium carbide precipitation temperature range of 800 ° F to 1500 ° F (427 ° C to 816 ° C). The 321 stainless steel pipe can stably form chromium carbide by adding titanium.
321 stainless steel is a titanium stabilized version of 304 for specific applications within the sensitization temperature range. Its anti-sensitization ability and its high strength at high temperature make it suitable for applications where 304 will be sensitized or 304L thermal strength is insufficient. When exposed to a slightly corrosive environment, there will be no intergranular corrosion of weld corrosion. However, welding 321 must not be used in a highly oxidizing environment because it is vulnerable to "knife line" erosion. However, 321 is a better choice in the working temperature environment of more than 500 ° C, so it has its own advantages. 321 stainless steel pipe is also conducive to high-temperature use due to its good mechanical properties. 321 stainless steel has higher creep and stress fracture properties than alloy 304, especially alloy 304L can also be considered for sensitive and intergranular corrosion problems.
321 stainless steel is basically made of 304 stainless steel. The difference between them is that very little titanium is added. The real difference is their carbon content. The higher the carbon content, the greater the yield strength. 321 stainless steel has advantages in high-temperature environments due to its excellent mechanical properties. Compared to SS304, 321 stainless steel has better ductility and stress fracture resistance. In addition, 304L can also be used to resist sensitization and intergranular corrosion.
