321 Stainless Steel Angle Bar
Product Details
Introduction
321 stainless steel, Ni-Cr-Mo-type austenitic stainless steel, its performance with a 304 stainless steel plate is very similar, but due to the addition of titanium, it has a better intergranular corrosion resistance and high temperature strength. The addition of titanium to make it effective control of the formation of chromium carbide .

321 stainless steel with Ti as a stabilizing element exists, but it is the creep strength of steel at high temperatures much better than 316L.

Stainless Steel Angle Bar
Stainless steel angel bar is perpendicular to each other on both sides of the strip into angular steel.

Stainless steel angel bar composed of various components of the force, but also for connections between components. Widely used in various building structures and engineering structures such as bridges, transmission towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse shelves.
