SUS420 is a hardenable 12% chromium steel with higher strength and hardness than 410, as well as better wear resistance than 410. The alloy is corrosion-resistant at room and moderate elevated temperatures, and retains high strength when heat treated, resulting in a mirror-like surface without chrome plating. This stainless steel alloy is known for its cleanliness, uniformity and good protection against corrosive hazards and is often used for long-term mold making, plastic mixtures, and storage in humid climates.
