5  .Chemical analysis

6:  6.1  This steel is of high-carbon, high-chrome alloy steel, which has high hardness and flexibility, as well as good effect of backfire. As a typical kind of steel, it is the best alloy steel in wear resistance so far.

      6.2  Added in molybdenum and vanadium, it has good properties of wear resistance, no deforming and impact resistance.

      6.3 With secondary refining, it is excellent in purity and tiny in granule. This steel is easy to cut, so it is adapted for make sharp knife, scissors, fretsaw, hardware punching die, forming roller, general cold-work die or hot-work finishing die, margin of roller, screw, line die, milling cutter, punching die, round roller, punching die for transformer, rolling cutter for steel, forming roller for steel pipe, particular forming roller, complex cold-work tool, metallurgy, tin-work die, plastic die, screw nobbing die and so on.
