Micro-Melt® 420-CW

Micro-Melt® 420-CW tool steel is a corrosion-resistant, high vanadium wear-resistant tool steel produced using the Micro-Melt powder process. The wear resistance of this grade is comparable to Micro-Melt A11-LVC alloy with toughness comparable to Micro-Melt A11 alloy. May be considered for applications where 440C and D2 tool steels do not have adequate wear resistance or for applications where A11-LVC, A11, D2 or other tool steels do not have adequate corrosion resistance. Many of the benefits realized in the use of Micro-Melt® powder metals, including ease of grinding, improved response to heat treatment, greater wear resistance, and increased toughness of the finished tool, are a direct result of the refined microstructure featuring smaller, more uniformly distributed carbide particles and a finer grain size, as well as the lack of segregation in the powder metallurgy product. In addition, Carpenter Technology's unique hot rolling and rotary forging capabilities impart minimal distortion characteristics to these alloys.
