Bohler-Uddeholm UDDEHOLM STAVAX® SUPREME Modified 420 (discontinued **)
Categories:	Metal; Ferrous Metal; Stainless Steel
Material Notes:	Cr-Ni-Mo-V alloyed Stavax® Supreme is an ESR re-melted tool steel, this provides a very pure material, with a minimum of inclusions. Purity is a requirement to be able to achieve the desired surface finish; it also contributes to better toughness. This grade is the right choice for larger tools where corrosion in production is unacceptable and where the requirements for good surface finish are high. Stavax® Supreme is characterized by: Good corrosion resistance Excellent through-hardening properties Good ductility and toughness Good wear resistance Excellent polishability
Key Words:	AISI 420 modified
