Alloy SteelOthers
Description (English)
CHLORIMET 3 is supplied as castings in the 2100°F water-quenched condition, delivering yield strength of 317 MPa, tensile strength of 496 MPa, elongation of 25%, and hardness of 220 HB. The alloy is manufactured to ASTM A 744 (general applications castings) and ASTM A 494 (castings). The balanced Cr + Mo composition with water quenching provides excellent resistance to both oxidizing and reducing chemicals. CHLORIMET 3 is widely used in chemical processing for handling wet chlorine, hypochlorite solutions, mixed acid solutions, and other aggressive media.
