Working with XM-32-H1100

Is XM-32 easy to machine?

Machine in condition A with rigid setups, sharp carbide, positive rake and 25–45 m/min; expect gummy chips and work hardening, finish-machine before or after aging with allowance for ~0.05 % growth.

Can XM-32 be welded?

Weldable by GTAW/PAW/EBW without preheat using matching or 17-4PH-type filler; re-solution treat and re-age for full joint strength, avoid heavy restraint on aged material.

Can XM-32 be formed, bent or molded?

Cold heading, upsetting and bending are best done in the annealed condition; hot work 1150 → 950 °C, then solution anneal ~1010 °C and air cool before aging.

What surface finishes work on XM-32?

Passivate in citric or nitric acid after machining; takes a bright mechanical or electropolish, and hard chrome/electroless nickel are options — bake after plating to avoid hydrogen embrittlement in the aged condition.

XM-32-H1100 — frequently asked

What is XM-32-H1100 used for?

XM-32-H1100 is typically used for high-strength bolts and studs, aerospace structural fittings, cold-headed screws and rivets, threaded rod and tie bars, machined shafts and pins and valve stems. In short: age-hardening fastener stainless; strength above 410/420; direct 17-4 PH alternative.

What is the yield strength of XM-32-H1100?

XM-32-H1100 has a typical yield strength of 930 MPa (135 ksi) and a tensile strength of 1,035 MPa (150 ksi) — stronger than 98% of stainless steel grades. Strength varies by condition: see the 7 listed tempers.

Is XM-32-H1100 easy to machine?

Not especially — machinability is rated fair (40/100, better than 72% of stainless steel grades). Machine in condition A with rigid setups, sharp carbide, positive rake and 25–45 m/min; expect gummy chips and work hardening, finish-machine before or after aging with allowance for ~0.05 % growth.

Can XM-32-H1100 be welded?

With care — weldability is rated fair (50/100). Weldable by GTAW/PAW/EBW without preheat using matching or 17-4PH-type filler; re-solution treat and re-age for full joint strength, avoid heavy restraint on aged material.

What surface finishes work on XM-32-H1100?

Passivate in citric or nitric acid after machining; takes a bright mechanical or electropolish, and hard chrome/electroless nickel are options — bake after plating to avoid hydrogen embrittlement in the aged condition.

Can XM-32-H1100 be formed, bent or molded?

Cold heading, upsetting and bending are best done in the annealed condition; hot work 1150 → 950 °C, then solution anneal ~1010 °C and air cool before aging.

What is the maximum service temperature of XM-32-H1100?

XM-32-H1100 is rated for continuous use to about 500°C (932 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between XM-32-A and XM-32-H900?

A is the default condition — pick for cold heading, machining and forming before a single low-temperature aging step. H900: highest strength/hardness condition for fasteners and shafts where ductility demands are modest. Yield strength is 745 MPa in A versus 1,205 MPa in H900.
