Abstract

PURPOSE:To produce a precipitation hardening high tensile stainless steel having excellent welding joint strength and toughness by incorporating specific ratios of C, Si, Mn, Ni, Cr, Mo, Ti, Al, S, N and O into Fe. CONSTITUTION:The stainless steel contg., by weight, <=0.03% C, 0.2-2.0% Si, <=0.5% Mn, 7.0-12.0% Ni, 7.5-12.0% Cr, 1.0-5.0% Mo, 0.2-1.0% Ti, <=0.035% Al, <=0.004% S, <=0.010% N, <=0.007% O and the balance Fe with inevitable impurities is prepd.; where in the range of said chemical components, when >=1.5% (<=2.0%) Si is incorporated thereto, Mo and Ti amounts are decreased in such a manner that <=7.0% Si+Mo+2XTi is satisfied (where >=1.0% Mo and >=0.2% Ti are regulated). The welding joint strength becomes >=170kg/mm at the time of forming an endless belt by welding and connecting the both ends of said stainless steel.
