What is Almar 362?
Almar 362 (S46020) is a low-nickel martensitic precipitation-hardening stainless steel that is soft and formable in the annealed martensitic condition and hardened by a single low-temperature age. In the aged condition it reaches about 1205 MPa yield, 1275 MPa tensile, 15 % elongation and 40 HRC (375 HB), with service to roughly 425 °C, and it cold forms considerably better than 17-4 PH. Corrosion resistance is moderate (rated 50 of 100) and stock is limited to bar and strip from few suppliers; 17-4 PH is the mainstream alternative. Almar 362 has a density of 7.76 g/cm³ (0.28 lb/in³), lighter than 58% of stainless steel grades. It melts at 1,400°C (2,552 °F). Almar 362 has a 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. Elongation at break is 15% and the elastic modulus is 200 GPa (29 Msi).

Working with Almar 362
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.

Almar 362 — frequently asked
What is Almar 362 used for?
Almar 362 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?
Almar 362 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 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 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 is the maximum service temperature of Almar 362?
Almar 362 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.
