When working temperature range from 1300 to 1500F, the hot forming method of ASTM A240 430 stainless steel round bars are usually hot-forming. And especially when 430 stainless steel round bars are on heavy sections.

ASTM A240 430 steel bars/sheet/coils/plates are usually manufactured with hot finish method. ASTM A240 430 steel bars/sheet/coils/plates own a high Cr content, 16.0-18.0%, which makes ASTM A240 430 steel bars/sheet/coils/plates own outstanding tensile strength. ASTM A240 430 steel bars/sheet/coils/plates can not be hardened by heat treatment. Any more technical issue about ASTM A240 430 steel bars/sheet/coils/plates can be talked with Katalor.
