Characteristics
420J1 stainless steel coil is a martensitic stainless steel, used after quenching and tempering, and has good cutting properties in the annealed condition. And 420J1 stainless steel coil has stable oxidation resistance below 700°C. 420J1 stainless steel coil is mainly used in the manufacture of parts requiring corrosion resistance, high strength, wear resistance and gauges, medical instruments, cutting tools and components.
420J1 characteristics: high quenching hardness, good corrosion resistance and nice machining performance. 420J1 has usually been used to produce steel ruler. Stainless steel ruler’s features are looks beautiful, flexible. nice wear and corrosion resistance.
