Title:
MIG WIRE FOR HIGH TENSILE STEEL
Document Type and Number:
Japanese Patent JPH03221294
Kind Code:
A
Abstract:
PURPOSE: To assure the safety of a steel structure by constituting the MIG wire of specific weight % of C, Si, Mn, Cu, Ni, Mo, Cr, Ti, Al, B, N, and the balance Fe.
CONSTITUTION: The components of the MIG wire for welding high-tensile steels is limited by weight % as follows: 0.03 to 0.09% C, 0.30 to 0.55% Si, 1.00 to 1.80% Mn, ≤ 0.01% P, S, 0.07 to 0.30% Cu, 2.40 to 3.00% Ni, 0.20 to 0.50% Mo, 0.20 to 0.90% Cr, 0.005 to 0.05% Ti, 0.003 to 0.02% Al, ≤ 0.0005% B, ≤0.0080% N, ≤ 0.005% Sb, As, Sn, ≤1.0% ratio of Ti/N and the balance Fe and unavoidable impurities. The good fracture toughness and Charpy impact characteristics are obtd. in this way.
