TP321
Material
- ◎ TP321, UNS S32100, 1.4541, X6CrNiTi18-10, 06Cr18Ni11Ti
Overview
TP321 stainless steel is an austenitic stainless steel of the Ni-Cr-Ti type, featuring corrosion resistance, high-temperature resistance, and creep resistance. It is usually applied to industries with high requirements for anti-grain-boundary-corrosion resistance.
Characteristics
-
- ◎ Good wear resistance
- ◎ high-temperature resistance and creep resistance
Application
It is used in the manufacture of acid-resistant containers, linings for wear-resistant equipment, and conveying pipes.
