Low-alloy steel electrodes

Low-alloy steel electrodes
Most wire falls into this category, including carbon steel welding wire, low-alloy structural steel welding wire, alloy steel wire, stainless steel wire and non-ferrous metal wire, etc. Common wire: SKD11 > 0.5 ~ 3.2mm HRC 56~58 welding cold steel, metal stamping dies, cutting dies, tooling, molding, work hard to make high hardness, wear resistance and high toughness of argon welding, heating preheated before welding, or easily cracked. 63 knife blade wire > 0.5 3.2mm HRC 63~55, mainly used in weld pull the die cutter, high hot hardness, and total hot forging die, brass, screws, and wear resisting hard, high speed steel, blade repair. SKD61 > 0.5 ~ 3.2mm HRC 40~43 welding of zinc, aluminum die casting, with good heat resistance and crack resistance, hot die forging, aluminum, aluminum copper copper mold, good heat resistance, wear resistance, resistance to cracking. Hot press mold, often tortoise shell cracks, mostly caused by thermal stresses, also due to surface oxidation or casting material corrosion caused by heat treatment to appropriate hardness to improve their life, hardness is too low or too high does not apply.
