Features
1.2080 is the best wear-resistant cold work tool steel. Heat treatment effect is stable.
Resistance welding electrode: Chromium zirconium copper through the combination of heat treatment and cold work to ensure performance, it can get the best mechanical properties and physical properties.
High carbon, high chromium type ledeburite cold work die steel, has good hardenability and good wear resistance.
usage
For the manufacture by the impact load is small, requiring a high wear-resistant cold die and punch.
Features and Scope: It is a widely used cold work die steel, with high strength, good hardenability and good wear resistance, but poor impact toughness. Mainly used to bear the impact load is small, requiring high wear-resistant die and punch, cold cut scissors, drill sets, gauges, drawing die, die stamping, rolling plate, drawing die and thread rolling die.
So for general purpose resistance welding electrodes, mainly as spot welding or seam welding of low carbon steel, coated steel plate electrode can also be used as a welding carbon steel electrode grip, shaft and gasket material, or as a convex welding Machine large molds, fixtures, stainless steel and heat-resistant steel mold or inlaid electrodes.
