Abstract
PURPOSE: To provide a free cutting austenite stainless steel maintaining an effect of improving the machinability due to the addition, of Pb, having improved hot workability, and consisting of a prescribed percentage each of C, Si, Mn, etc. and one or more among S, Se, Pb, etc., and the balance essentially Fe.
CONSTITUTION: This free cutting austenite stainless steel contains ≤0.2% C, ≤2.0% Si, 5W20% Mn, ≤15% Ni, 16W30% Cr, 0.03W0.40% Pb, 0.0005W0.030% B, ≤0.10% N and additionally one or more among 0.07W0.40% S, 0.01W0.40% Se, 0.01W0.40% Te, 0.01W0.40% Bi and 0.001W0.080% Ca. Unfavorable influence on the hot workability of the steel due to the combined addition of Pb and S, Se, Te, Bi or Ca as machinability improving elements is eliminated by adding either an adequate amount of B or B and Al, Ti, Nb, etc. In order to maintain the machinability and hot workability and to enhance the corrosion resistance, Mo and Cu may be added.
