The foundry upgrades its heat treatment workshop and develops differentiated heat treatment schedules for stainless steel, carbon steel and low alloy steel castings. Solution treatment improves corrosion resistance of stainless steel castings; normalizing stabilizes metallographic structure for carbon steel; quenching and tempering boosts strength, toughness and impact resistance of low alloy steel castings. It reduces casting deformation and cracking and extends service life of hardware castings under heavy load and impact conditions. Products serve mining machinery, fluid equipment and rail transit components. Full heat treatment inspection reports can be supplied.
