Chrome Vanadium - ASTM A 231 - Spring Wire Properties

The alloy spring steels have a definite place in the field of spring materials, particularly for conditions involving high stress and for applications where shock or impact loading occurs. Alloy spring steels also can withstand higher and lower temperatures than the high-carbon steels and are obtainable in either the annealed or pre tempered conditions. Note: These materials are not regularly stocked in a wide variety of sizes.
