Abstract

PURPOSE: To obtain a tough nitriding steel with increased resistance to temper brittleness during nitriding by adding proper amounts of C, Ni, Cr, Mn, Mo, V, etc. and a very small amount of sol. Al to Fe.
CONSTITUTION: This tough nitriding steel consists of, by weight, 0.25W0.50% C, ≤0.50% Si, ≤1.00 Mn, ≤0.020% P, ≤0.020% S, 1.50W2.50% Ni, 1.50W2.50% Cr, 0.20W0.70% Mo, 0.05W0.20% V, 0.010W0.10% sol. Al, ≤0.0020% O, and the balance Fe with inevitable impurities. said proper amounts of C, Ni, Cr, Mo, V, etc. are added to provided high toughness to the steel, and Al deteriorating the toughness is restructed to said very small amount. The amounts of P and S are reduced, the amounts of Si, Mn, Ni and Cr are made proper, and Mo and V are effectively added to enhance the tempering resistance. Cr, Mo and V are added by said proper amounts to enhance the nitriding characteristics.
