| 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." |
