Features and Applications
Similar to HW alloy but has greater strength and resistance to hot gas corrosion up to 2100 deg. F. This grade is used more commonly than HW alloy for severe applications with water or synthetic quenches. Used for trays, baskets, fixtures, hearth plates, enameling tools and retorts where severe thermal shock is present. |
