Principles of marking

Steels of similar purpose are distinguished by the increased content of carbon (it should be not less than 0.5%) and silicon. Particularly responsible products are made of alloyed steels with the addition of vanadium and chromium (less often - nickel). Accordingly, marking of domestic grades of spring steels includes the letters G (manganese), X (chromium), F (vanadium), S (silicon). Steels with tougher restrictions on chemical composition and technological melting modes have the letter, A (steel of improved quality) at the end of the designation.
