  ● 15-5pH what materials:
  Is martensitic, precipitation hardened, chrome-nickel-copper stainless steel, with good surface smoothness and dimensional stability. Processing technology is good, excellent mechanical properties, resistance to general corrosion environment. Cidong early as the mid-nineties to promote the steel bell, is Shanghai's first production and management of the steel companies. The steel strength, transverse toughness and ductility, hardness and corrosion resistance of stainless steel with 304. 15-5pH or heat treatment may be used to solve in the treatment of performance.
