51CrV4 and 1.8159 flat products
51KhFA, 51CrV4 and material number 1.8159 are used in cross-reference practice for chromium-vanadium spring steels. They must not be treated as automatically interchangeable: chemistry, product standard, delivery condition, decarburization limits and mechanical requirements can differ. The purchaser should identify the accepted designation and standard edition before quotation.
Sheet, strip and cut blank requirements
For sheet or strip, state thickness, width, length or coil data, edge condition, surface, flatness, temper or heat-treated condition and quantity. Add the required hardness or mechanical-property range, testing direction, dimensional tolerance and certificate type. If blanks will be formed or heat treated after delivery, describe the process so the supplier can confirm a suitable starting condition.
