410S Stainless Steel Plate – Superior Weldability & Ferritic Strength for Heavy Fabrication
Introduction
When refinery maintenance managers need a 410S stainless steel plate that can be welded without post-weld cracking, they don’t gamble on standard 410. They specify low-carbon 410S stainless steel plate because its restricted carbon 0.08 % max eliminates sensitization, preserves ductility and removes the costly post-weld anneal that 410 demands. For heat-exchanger shells, thermal oxidizer ducts and pressure-vessel shells, 410S stainless steel properties deliver ferritic scaling resistance up to 650 °C while costing 20–30 % less than 304L. Add excellent 410S stainless steel weldability, uniform 410S stainless steel magnetic response for easy lifting, and ready availability from top 410S stainless steel plate suppliers, and you get a fabrication-friendly solution that slashes shop time and total project cost. Whether you need a single 410S stainless steel sheet for a tube sheet or 200 tons of ferritic 410S stainless steel plate for a flare stack, this page gives you every technical detail, comparison and 410S stainless steel data sheet value you need—plus the fastest, most reliable 410S stainless steel plate price quotation on the planet.

410S stainless steel plate is the low-carbon version of grade 410. By holding carbon to 0.08 % maximum, the alloy avoids chromium carbide precipitation during welding, so thick sections retain full intergranular corrosion resistance and impact toughness. The balanced 410S stainless steel composition of 11.5–13.5 % Cr with Ni ≤0.60 % keeps the material fully ferritic from room temperature to melting, giving uniform thermal expansion and predictable 410S stainless steel weldability across large pressure-vessel shells. For fabricators who need scaling resistance, moderate corrosion resistance and freedom from costly post-weld heat treatment, low-carbon 410S stainless steel plate is the clear choice.

Welding & Fabrication Guide
{: alt="410S stainless steel data sheet infographic"}- Preheat: normally not required ≤25 mm; 100–150 °C for thicker 410S stainless steel plate in restrained joints.
- Inter-pass: keep ≤200 °C to avoid grain growth.
- Filler: AWS E/ER 309L for dissimilar joints; ER 410S or ER 308L for matching colour.
- Post-weld heat treatment: usually unnecessary; for maximum ductility stress-relieve at 650 °C, air cool.
- Why 410S is preferred over 410: 410S stainless steel weldability eliminates hard martensite formation, so thick shells cool without cracking and require no PWHT to regain toughness—saving days in shop schedule.
Major Applications
- Petrochemical refinery hydrocracker shells
- Thermal oxidizer reactor ducts
- Heat-exchanger tube sheets and baffles
- Pressure-vessel shells for sour service
- Furnace retorts and radiant tubes
- Automotive exhaust flex-pipe flanges
- Power plant coal chute liners
- Waste-to-energy boiler tube shields

FAQ Section
Q1: Why choose 410S over 410?
A1: 410S vs 410 stainless steel—410S contains only half the carbon, preventing martensite formation and weld cracking. You save the cost of post-weld heat treatment and gain as-welded ductility.
Q2: Is 410S stainless steel magnetic?
A2: Yes, it is fully ferritic 410S stainless steel plate, so it exhibits strong 410S stainless steel magnetic response ideal for lifting, separation and induction heating.
Q3: Can 410S be heat treated for higher hardness?
A3: No. Because carbon is restricted, 410S cannot be hardened by quench & temper; use 410 or 420 instead if higher hardness is required.
Q4: Maximum service temperature of 410S?
A4: 650 °C (1 200 °F) in continuous service; intermittent up to 815 °C for oxidation-resistant furnace parts.
Q5: Best welding method for 410S plate?
A5: GTAW (TIG) with ER 309L filler gives clean, ductile joints; for heavy low-carbon 410S stainless steel plate SAW with 309L flux wire is economical.
Q6: Does 410S rust?
A6: In mild corrosives (pH >4, chloride <200 ppm) 410S performs well; above that use 304L or 316L. Regular rinse prevents surface rust in marine atmospheres.
Q7: Difference in corrosion resistance 410S vs 410?
A7: Practically identical in the annealed state; however, after welding 410 suffers sensitized grain boundaries and may rust, whereas 410S stainless steel plate remains corrosion-resistant.
