What does "GHS-70" wire mean?
High strength steel wire, tensile strength 630MPa.
GHS-70 is a 700Mpa grade high strength steel welding wire, which has excellent comprehensive mechanical properties. GHS-70 adopts mixed gas, it can weld the low strength alloy steel structure of corresponding strength level, and is widely used in the welding of hydraulic support and scraper chain wheel of coal mine machinery.The welding wire is made of H08Mn2SiA wire rod steel, drawn and treated by surface copper plating. It is used as CO2 gas shielded welding wire, with less spatter and good anti porosity performance.Application: Welded low carbon steel and some low alloy steel structure.The chemical composition of welding wire (%) C = 0.11 Si:0.65~0.95 Mn:1.80~2.10 = 0.20 Cr Ni = 0.30, S = 0.030, P = 0.030, Cu = 0.50Electrode diameter: 0.8, 1, 1.2, 1.6, 2, 2.5, 3.2 (mm)Attentions: clean the oil and rust on the surface of the workpiece before welding, and select the suitable welding specification.
GHS60 GHS70 GHS80 is the raw material grade of the steel mill, which was first supplied by shougang. Later, the steel mills also continued development, but the name of the product is different. The GHS70 brand is H08Mn2SiNiMoA or H08Mn2SiNiMoTiA.
