World Leading 15-5 PH Stainless Steel Manufacturer

15-5 PH stainless steel also referred to as UNS S15500 or XM-12. It is a precipitation-hardening alloy composed of nickel, copper, chromium, and phosphorus element.

Due to the presence of copper in the alloy, the 15-5 PH stainless steel has a high corrosion cracking resistance. Thus, suitable for use in a variety of high-temperature applications and industries.  

15-5 PH stainless steel also has good weldability and machinability. It can be easily welded using standard welding techniques and is compatible with most machining processes.

At Tuolian, we manufacture 15-5 PH stainless steel in wide forms such as flanges, fittings, sheets, pipes, tubes, bars, fasteners, and more. Available in various sizes, thicknesses, and shapes depending on your requests.

Manufacturing Processes

Tuolian is expert in various processes used for manufacturing 15-5 PH stainless steel:

  • Melting – The stainless steel is melted in a furnace or an electric arc furnace. The molten steel is then cast into various shapes & sizes.
  • Heat Treatment – After hot rolling, the steel is annealed to reduce internal stresses & improve the machinability. The steel is then hardened by heating it to a high temperature & then cooling it rapidly in water or oil.
  • Hot Rolling – The cast steel is reheated. Then rolled into different forms such as plates, sheets, or bars.
  • Cold Working – Cold working methods includes cold rolling, drawing, or forging. This enhances the mechanical properties & surface finish of the steel.
  • Welding – Tuolian 15-5 PH stainless steel can be welded using traditional welding techniques including gas metal arc welding, gas tungsten arc welding, & resistance welding.  
  • Machining – 15-5 PH stainless steel can be machined using carbide tooling & proper cutting parameters.
  • Finishing – We finish the steel by polishing, grinding, or coating to achieve the desired surface finish & appearance.
