What is 410S Annealed?
410S Annealed is 410S in the Annealed temper — standard stocked condition for plate, sheet, bar and tube; maximum weldability and formability, non-hardening. 410S Annealed has a yield strength of 265 MPa (38.4 ksi) and a tensile strength of 460 MPa (66.7 ksi) — weaker than 80% of stainless steel grades. Elongation at break is 30% and the elastic modulus is 200 GPa (29 Msi). 410S Annealed has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,480°C (2,696 °F).

Working with 410S Annealed
Is 410S easy to machine?
Machines like a soft 12Cr stainless (~60 % of 1212): use rigid setups, sharp positive-rake carbide, moderate speed with heavy flood coolant to avoid gumming and work-hardened skins.
Can 410S be welded?
Readily welded by GTAW/GMAW/SMAW with 309L or matching filler; 150–250 °C preheat plus 700–760 °C post-weld anneal is recommended on thick sections to restore HAZ ductility.
Can 410S be formed, bent or molded?
Cold forms and roll-bends adequately but with higher springback and less stretch than 304; allow generous bend radii and avoid severe deep drawing.
What surface finishes work on 410S?
Passivate or electropolish after pickling; takes a good bright polish but must be kept dry — no anodizing, and painting or plating is used for outdoor/chloride exposure.
410S chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

410S Annealed — frequently asked
What is 410S Annealed used for?
410S Annealed is typically used for welded petroleum equipment, industrial valves, refinery tower linings and trays, pressure-vessel cladding, heat exchanger baffles and supports and furnace parts and annealing boxes. In short: lower-carbon martensitic sheet.
What is the yield strength of 410S Annealed?
410S Annealed has a typical yield strength of 265 MPa (38.4 ksi) and a tensile strength of 460 MPa (66.7 ksi) — weaker than 80% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is 410S Annealed easy to machine?
Reasonably — machinability is rated fair (50/100, better than 90% of stainless steel grades). Machines like a soft 12Cr stainless (~60 % of 1212): use rigid setups, sharp positive-rake carbide, moderate speed with heavy flood coolant to avoid gumming and work-hardened skins.
Can 410S Annealed be welded?
Yes — weldability is rated very good (70/100). Readily welded by GTAW/GMAW/SMAW with 309L or matching filler; 150–250 °C preheat plus 700–760 °C post-weld anneal is recommended on thick sections to restore HAZ ductility.
What surface finishes work on 410S Annealed?
Passivate or electropolish after pickling; takes a good bright polish but must be kept dry — no anodizing, and painting or plating is used for outdoor/chloride exposure.
Can 410S Annealed be formed, bent or molded?
Cold forms and roll-bends adequately but with higher springback and less stretch than 304; allow generous bend radii and avoid severe deep drawing.
What is the maximum service temperature of 410S Annealed?
410S Annealed is rated for continuous use to about 700°C (1,292 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 410S Annealed and 410S-BA?
Annealed is the default condition — standard stocked condition for plate, sheet, bar and tube; maximum weldability and formability, non-hardening. BA: use where a reflective as-annealed surface is needed without mechanical polishing. Yield strength is 265 MPa in Annealed versus 275 MPa in BA.
