Title:
WELDING MATERIAL FOR NITRIC ACID RESISTANT STAINLESS STEEL
Document Type and Number:
Japanese Patent JPS62179892
Kind Code:
A
Abstract:
PURPOSE: To obtain a welding material which makes a weld metal having the substantial corrosion resistance to a highly corrosive nitric acid soln. and has high resistance to high-temp. cracking by specifying chemical components.
CONSTITUTION: This nitric acid resistant stainless steel welding material is a material for nitric acid resistant TIG welding or MIG welding and has the chemical components contg., by weight % ≤0.02% C, ≤0.15 Si, 3W6% Mn, ≤0.01% P, ≤0.01% S, 20W22.5% Ni, 25W28% Co and 0.05W0.3% N and consisting of the balance Fe. The weld zone having the high corrosion resistance and the high resistance to high-temp. cracking is thereby obtd.
