Product Description

BUDERUS?**1 vacuum melting chrome-nickel-manganese alloy steel has been heat treat before leaving factory. The hardness reaches to HB******5. It is fine in organization, much low in the content of sulfide and oxid, excellent in polishing and texture, high in strength and flexibility, resistant to impact, more predominant in high temperature than ***1, ***8; what? more, nitrogen treatment can also be done on the surface. It is used to make molding die that demands for high polishing and needs to press or ejector in high temperature. Characteristics: The pre-hardened nickel-chrome-molybdenum alloy tool steel is strong in flexibility, resistant to pressure, easy to polish and is able to nitrogenize.
