H13 what kind of welding rod is used for steel welding?
H13 steel electrodeH13 steel is C-Cr-Mo-Si-V steel, which is widely used in the world. At the same time, many scholars in various countries have conducted extensive research on it, and explored the improvement of chemical composition.H13 steel is C-Cr-Mo-Si-V steel, which is widely used in the world. At the same time, many scholars in various countries have conducted extensive research on it, and explored the improvement of chemical composition. Steel is widely used and has excellent properties, mainly determined by the chemical composition of steel. Of course, impurities in steel must be reduced. Data show that when Rm is at 1550MPa, the sulfur content of the material drops from 0.005% to 0.003%, which increases the impact toughness by about 13J. Obviously, the NADCA 207-2003 standard provides: (premium) H13 steel grade sulfur content less than 0.005%, while the super (superior) should be less than 0.003%S and 0.015%P. The composition of H13 steel is analyzed below.
H13 is because the hot die die, as far as possible without welding, such as welding and molding after then try to use the stainless steel welding rod or wire, if you need to have the strength of welding, preheating in the best welding preheating temperature between 500-600 degrees is appropriate, the good after welding with some insulation material covering. Such as asbestos, the slow cooling speed, reduce welding stress.Avoid soldering prior to heat treatment.
