SUPER 13Cr (95 ksi) / UNS 41426 / EN 1.4415

• Applications

  Commonly used in the same area as AISI 4130, 4140 and 4145 but often in environment, which have a high content of sulfur.

  • Oil & Gas Industry: Tubing and casing for wells (especially in sweet and mildly sour environments), Downhole tools and completion equipment, Flowlines and manifolds in moderate chloride conditions.
  • Marine & Offshore: Pump shafts and valve components exposed to seawater splash zones, Subsea hardware requiring high strength and moderate corrosion resistance.
  • Power Generation: Turbine components and shafts, High-strength parts in steam environments.
  • General Engineering: Heavy-duty shafts and couplings, Components requiring high mechanical strength and moderate corrosion resistance.

• Heat Treatment & Weldability

  Heat Treatment: Hardened and tempered.

  Weldability: Moderate.
