CarTech Micro-Melt 420-CW tool steel is a corrosion-resistant, high vanadium wear-resistant tool steel produced using Carpenter's CarTech Micro-Melt powder process. The wear resistance of this grade is comparable to CarTech Micro-Melt A11-LVC alloy. CarTech Micro-Melt 420-CW alloy also is comparable in toughness to CarTech Micro-Melt A11 alloy. CarTech Micro-Melt 420-CW may be considered for those 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 CarTech Micro-Melt powder metals, such as CarTech Micro-Melt 420-CW alloy, are a direct result of the refined microstructure (small, uniformly distributed carbide particles and a fine grain size) and the lack of segregation in the powder metallurgy product. These advantages include ease of grinding, improved response to heat treatment, greater wear resistance, and increased toughness of the finished tool.

Applications:
CarTech Micro-Melt 420-CW alloy may be considered for:

• Plastic injection molds and inserts
