Processing Characteristics
Welding
Can be welded using all conventional methods without pre-heating. Care should be taken to prevent weldment stresses.
Machining
Can be machined in solution-treated condition with machining rates similar to grade 304 stainless steel.
Applications
  • Engine components
  • High strength and boat propeller shafts
  • Plastic moulding dies
  • Valves and gears
