Working with Almar 362-H900
Is Almar 362 easy to machine?
Machine in the annealed condition with rigid setups, positive-rake carbide, heavy feeds and flood coolant; expect ~35–45 % of AISI 1212 and account for ~0.05–0.1 % growth on aging.
Can Almar 362 be welded?
GTAW/PAW autogenously or with matching/347 filler; keep heat input low, then re-solution-anneal and age for full properties (a straight age recovers most strength).
Can Almar 362 be formed, bent or molded?
Cold form, bend and deep-draw in the annealed martensitic temper — it is notably more formable than 17-4 PH — then harden with a single low-temperature age with minimal distortion.
What surface finishes work on Almar 362?
Takes a fine mechanical polish and passivates per ASTM A967; avoid hydrogen-charging plating processes in peak-aged tempers or bake at 190 °C after plating.

Almar 362-H900 — frequently asked
What is Almar 362-H900 used for?
Almar 362-H900 is typically used for fasteners, shafts, cutlery-grade components and industrial hardware. In short: most formable PH stainless; low-nickel 17-4 PH alternative; single-step age hardening.
What is the yield strength of Almar 362-H900?
Almar 362-H900 has a typical yield strength of 1,205 MPa (175 ksi) and a tensile strength of 1,275 MPa (185 ksi) — stronger than 99% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is Almar 362-H900 easy to machine?
Not especially — machinability is rated poor (32/100, worse than 62% of stainless steel grades). Machine in the annealed condition with rigid setups, positive-rake carbide, heavy feeds and flood coolant; expect ~35–45 % of AISI 1212 and account for ~0.05–0.1 % growth on aging.
Can Almar 362-H900 be welded?
Yes — weldability is rated good (60/100). GTAW/PAW autogenously or with matching/347 filler; keep heat input low, then re-solution-anneal and age for full properties (a straight age recovers most strength).
What surface finishes work on Almar 362-H900?
Takes a fine mechanical polish and passivates per ASTM A967; avoid hydrogen-charging plating processes in peak-aged tempers or bake at 190 °C after plating.
Can Almar 362-H900 be formed, bent or molded?
Cold form, bend and deep-draw in the annealed martensitic temper — it is notably more formable than 17-4 PH — then harden with a single low-temperature age with minimal distortion.
What is the maximum service temperature of Almar 362-H900?
Almar 362-H900 is rated for continuous use to about 425°C (797 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Almar 362-H900 and Almar 362-A?
H900 is the default condition — standard peak-strength condition: highest tensile/yield with useful ductility, for springs, shafts and fasteners. A: choose for blanking, deep drawing, cold forming and machining before the single low-temperature aging cycle. Yield strength is 1,205 MPa in H900 versus 760 MPa in A.
