ABSTRACT:
A spring steel having a good durability and a good sag-resistance consisting essentially of by weight 0.35-0.55% carbon, 1.80-3.00% silicon, 0.50-1.50% manganese, 0.50-3.00% nickel, 0.10-1.50% chromium, 0.01-0.05% aluminum and 0.010-0.025% nitrogen, the remainder being iron and inevitable impurities.
The spring steel has been completed for the purpose of obtaining a spring steel having a high toughness in a high hardness of not less than HRC 55 and having a good sag-resistance, in particular examining the contents of nickel, chromium and nitrogen in addition to the carbon content.
