Working with Custom 465-H1150
Is Custom 465 easy to machine?
Rough machine in Condition A with sharp, rigid, positive-rake carbide tooling and heavy flood coolant; finish after aging with low feeds since aged 47–51 HRC material work-hardens and is abrasive due to Ti.
Can Custom 465 be welded?
Good GTAW/EBW/laser weldability with matching or 465 filler, no preheat needed; re-solution-anneal plus age (or at minimum re-age) after welding to restore joint strength.
Can Custom 465 be formed, bent or molded?
Cold form, bend and cold draw only in Condition A; aged material is essentially non-formable, and hot work should be done above ~1000 °C with slow cooling.
What surface finishes work on Custom 465?
Passivate per ASTM A967/AMS 2700 after machining; takes a high mirror polish for surgical use; avoid electroplating in peak-aged tempers or bake for hydrogen embrittlement relief.

Custom 465-H1150 — frequently asked
What is Custom 465-H1150 used for?
Custom 465-H1150 is typically used for aircraft structural fittings, landing gear components, actuator shafts and rods, high-strength aerospace fasteners, helicopter rotor hardware and drive shafts. In short: premium high-strength PH stainless.
What is the yield strength of Custom 465-H1150?
Custom 465-H1150 has a typical yield strength of 1,170 MPa (170 ksi) and a tensile strength of 1,275 MPa (185 ksi) — stronger than 98% of stainless steel grades. Strength varies by condition: see the 8 listed tempers.
Is Custom 465-H1150 easy to machine?
Not especially — machinability is rated poor (32/100, worse than 62% of stainless steel grades). Rough machine in Condition A with sharp, rigid, positive-rake carbide tooling and heavy flood coolant; finish after aging with low feeds since aged 47–51 HRC material work-hardens and is abrasive due to Ti.
Can Custom 465-H1150 be welded?
With care — weldability is rated fair (52/100). Good GTAW/EBW/laser weldability with matching or 465 filler, no preheat needed; re-solution-anneal plus age (or at minimum re-age) after welding to restore joint strength.
What surface finishes work on Custom 465-H1150?
Passivate per ASTM A967/AMS 2700 after machining; takes a high mirror polish for surgical use; avoid electroplating in peak-aged tempers or bake for hydrogen embrittlement relief.
Can Custom 465-H1150 be formed, bent or molded?
Cold form, bend and cold draw only in Condition A; aged material is essentially non-formable, and hot work should be done above ~1000 °C with slow cooling.
What is the maximum service temperature of Custom 465-H1150?
Custom 465-H1150 is rated for continuous use to about 450°C (842 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Custom 465 Condition A and Custom 465-H900?
Condition A is the default condition — stock and machining condition — lowest strength, best formability; age after rough machining. H900: peak-strength condition for maximum tensile/hardness where toughness and SCC margin are secondary. Yield strength is 795 MPa in Condition A versus 1,690 MPa in H900.
