Description
Kh6VF / EI808 cold-work tool steel
Kh6VF, also written KH6VF or EI808, is a tool-steel designation used for selected cold-work tooling and cutting applications. The designation must be tied to the governing standard because transliteration, heat-treatment condition and acceptance requirements can vary between documents.
Typical applications
Published uses include dies, rolls, punches, cutting and milling tools, measuring components and other tools intended for cold deformation or wear service. This list is informational only; suitability depends on section size, required hardness, toughness, heat treatment and the actual loading of the component.
Supply information
State whether bar, round, forging, plate or another form is required. Include dimensions, tolerances, delivery and heat-treatment condition, surface or machining allowance, quantity and required inspection documents. Do not substitute another tool-steel grade without an engineering review.
