Grade 630 stainless steels angles & channels are martensitic stainless steels that are precipitation hardened to achieve excellent mechanical properties. These steel achieve high strength and hardness following heat treatment. The heat and corrosion resistance of grade 630 angles & channels are similar to that of grade 304 steels. This grades is also commonly referred to as grade 17-4PH.

One of the key benefits of this grade is that it is available in solution treated conditions, at which they can be easily machined and age-hardened to attain high strength. The age treatment of grade 630 angles & channels is carried out at low temperatures, to avoid significant distortion. Therefore, this grade is used for applications such as the manufacture of long shafts that do not require re-straightening after heat treatment. The properties mentioned below pertain to commonly available grade 630 flanges products in ASTM A564. The specifications may not be similar to other forms such as forgings and plates.

Applications

  • Aerospace – piston engine manifolds
  • Chemical Processing
  • Expansion Joints
  • Food Processing – equipment and storage
  • Petroleum Refining – polythionic acid service
  • Waste Treatment – thermal oxidizers

Benefits

  • Higher creep stress and rupture properties when compared with 304
  • Ideal for high temperature service
  • Overcomes sensitization and intergranular corrosion concerns
  • Can be used in elevated temperature applications for ASME Boiler and Pressure Vessel Code applications
  • Excellent mechanical properties
