45XH2MOA

Product Description:

45XH2MОА is a low-carbon alloy steel that delivers exceptional strength and toughness after heat treatment. The presence of chromium and molybdenum improves its resistance to wear and enhances its ability to retain mechanical properties under high-stress conditions. Nickel provides additional toughness and moderate corrosion resistance.
