And a method of manufacturing the welded joints and welding material of martensitic stainless steel

摘要

PROBLEM TO BE SOLVED: To provide a welding material of a martensite system steel containing about 10.5-14% Cr.;SOLUTION: This material comprises 0.1-1.0% Si, 0.1-4.0% Mn, 9.5-14.0% Cr, 4.0-9.0% Ni, 0.3-4.0% MO, 0.05-0.50% Ti, 0-2.0% W, 0-2.0% Cu, 0.03% or less C, N, and P respectively, 0.01% or less S, and 0.04% or less Al. In the formula: Ni balance (%)=30×%C+0.5×%Mn+%Ni+8.2-1.1(1.5×%Si+%Cr+%Mo), the Ni balance is -0.7-2.0, and also in the formula: Cr equivalence (%)=1.5×%Si+%Cr+%Mo, the Cr equivalence is 11-17.;COPYRIGHT: (C)2000,JPO
