About ER 630

ER630 is a precipitation-hardening, martensitic stainless steel filler metal (like 17-4 PH) used for welding similar high-strength stainless steels, offering excellent mechanical properties that can be further enhanced by post-weld heat treatments (like solution treating and aging) to achieve high strength, making it ideal for parts like valves, gears, and fasteners. 
Key Characteristics:
  • Type: Precipitation-Hardening (PH) Stainless Steel (often referred to as 17-4 PH).
  • Classification: AWS A5.9 ER630.
  • Purpose: To weld materials of similar composition, such as ASTM A564 Type 630, for applications requiring high strength and good corrosion resistance.
  • Microstructure: Modified to prevent undesirable ferrite formation, maintaining good mechanical properties in the martensitic structure.
  • Versatility: Can be used in the as-welded condition or heat-treated (solution treated and aged) to significantly increase strength and hardness. 
Applications:
  • Valves, fasteners, gears, propeller shafts, and roller chain pins. 
Benefits:
  • High strength in the heat-treated condition.
  • Good corrosion resistance. 
In essence, ER630 provides a strong, reliable weld for demanding stainless steel applications where strength is critical.
