Supplier KMZ offers round, rod and wire of high carbon tool steel die stamps 4KH4VMFS (ДИ22) at economical price. The provider ensures timely delivery of products at any address specified by the consumer. The price is the best in this segment of the rental.

Technical characteristics

Instrumental of die steel 4KH4VMFS (ДИ22) refers to steels with improved heat resistance and toughness. This steel is used for making inserts stamps CGSP, gorjachekatanogo and punching tools, press dies for hot extrusion and high-speed pneumatic hammers and gidrobiontov presses, moulds for casting copper alloys under pressure. A characteristic feature of steel is its complex alloying and the tendency to dispersion hardening, which positively affects the tool life, enhances strength, hardenability and heat resistance (the material does not lose its properties when heated to temperatures of 620…650°C).
