Principal Design Features
|
|
This is a martensitic, precipitation hardening, chromium-nickel-copper stainless steel. The alloy combines good strength, transverse toughness and ductility, hardness capability and corrosion resistance compared with 304 stainless. It may be used in the solution treated condition or heat treated to obtain a wide variety of properties.
|
|
|
Applications
|
|
Aircraft components, fabricated parts in high pressure corrosive environments including valves, shafts, fasteners, fittings and gears.
|
|
|
Machinability
|
|
This alloy may be machined in any of the attainable conditions, however machining in H1150M will yield best tool life.
|
|
|
Forming
|
|
This alloy is capable of being only mildly formed. If forming is required, do so in the overaged condition for best results.
|
|
|
Welding
|
|
Resistance methods or shielded fusion is recommended. Use AWS E/ER630 for filler metal.

Heat Treatment
|
|
CONDITION A--Soak at 1900 F(1038 C) for 1/2 hour, air cool. CONDITION H 900--Soak Condition A material at 900 F(482 C) for 1 hour, air cool. CONDITION H 925, H 1025, H1075, H 1100, H 1150--Soak Condition A material at desired temperature for 4 hours, air cool. CONDITION H 1150M--Soak Condition A material at 1400 F(760 C) for 2 hours, air cool. Heat to 1150F(621 C) for 4 hours, air cool.

Hot Working
|
|
This alloy works well in all common hot working procedures. Material should be annealed after hot working for best heat treat response.
|
|
|
Cold Working
|
|
Cold work is restricted only by this alloys high initial yield strength. The alloy is not favored for cold working but can be moderately formed.
|
|
|
Annealing
|
|
1900 F (1038 C) for 1 hour, rapid cooling. Also known as " solution treating."
