Working with S32562
Is S32562 easy to machine?
Treat as a low-machinability super duplex: rigid setups, positive-rake coated carbide, 60–90 m/min surface speed, heavy feeds to cut under the work-hardened layer and copious coolant.
Can S32562 be welded?
GTAW/GMAW/SMAW with 25Cr super duplex (or Cu-bearing matching) filler, interpass ≤150 °C, heat input roughly 0.5–1.5 kJ/mm and Ar+N₂ backing to keep ferrite 35–55% and avoid intermetallics.
Can S32562 be formed, bent or molded?
Hot work 1000–1200 °C with prompt solution anneal and water quench; cold forming needs 2× the force of 316L, generous bend radii and allowance for high springback.

What surface finishes work on S32562?
Pickle and passivate (HNO₃/HF) after any hot work or welding to restore the passive film; electropolishing or mechanical polishing gives good surfaces — no anodizing.

S32562 — frequently asked
What is S32562 used for?
S32562 is typically used for sulfuric acid handling equipment, chemical process piping, flue gas desulfurization scrubbers and seawater equipment. In short: super duplex for reducing acids; 620 MPa yield strength; low machinability, 300 °C limit.
What is the yield strength of S32562?
S32562 has a typical yield strength of 620 MPa (89.9 ksi) and a tensile strength of 860 MPa (125 ksi) — stronger than 88% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is S32562 easy to machine?
Not especially — machinability is rated poor (25/100, worse than 88% of stainless steel grades). Treat as a low-machinability super duplex: rigid setups, positive-rake coated carbide, 60–90 m/min surface speed, heavy feeds to cut under the work-hardened layer and copious coolant.
Can S32562 be welded?
Yes — weldability is rated good (60/100). GTAW/GMAW/SMAW with 25Cr super duplex (or Cu-bearing matching) filler, interpass ≤150 °C, heat input roughly 0.5–1.5 kJ/mm and Ar+N₂ backing to keep ferrite 35–55% and avoid intermetallics.
What surface finishes work on S32562?
Pickle and passivate (HNO₃/HF) after any hot work or welding to restore the passive film; electropolishing or mechanical polishing gives good surfaces — no anodizing.
Can S32562 be formed, bent or molded?
Hot work 1000–1200 °C with prompt solution anneal and water quench; cold forming needs 2× the force of 316L, generous bend radii and allowance for high springback.
What is the maximum service temperature of S32562?
S32562 is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between S32562-SA and S32562 CR-2B?
SA is the default condition — standard supply condition for plate, forgings, bar and tube — balanced 50/50 ferrite/austenite with full corrosion resistance. CR-2B: thin sheet ≤6 mm for tank linings and cladding; slightly higher strength and better surface than hot-rolled plate. Yield strength is 620 MPa in SA versus 650 MPa in CR-2B.
How much does S32562 cost?
S32562 is a high-cost stainless steel ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
