ASTM A240 321H stainless steel plate, A240 321H steel sheet Surface finish

ASTM A240 321H stainless steel plate is commonly called ASTM A240 321H Chromium-Nickel steel. A240 321H steel sheet is a very good stability of stainless steel. At temperatures up to 800-1500 ° F (427-816 ° C), chromium carbide precipitation under conditions, can still maintain good resistance to intergranular corrosion ability.

A240 21H stainless steel sheet is a widely used stainless steel, where parts are heated within carbide-precipitation temperature range and exposed to corrosive atmosphere.321H tainless steel due to its excellent mechanical properties at high temperature environment is very advantage. Compared with the 304 alloy, 321H stainless steel has better ductility and resistance to stress cracking capacity.
