Stainless Steel 410 Sheet
Stainless Steel 410 Sheets are a high-performance, martensitic stainless steel that offers excellent strength, durability, and moderate corrosion resistance. Known for its high hardness and ability to be heat-treated, 410 stainless steel sheets are ideal for applications requiring strength and resistance to wear. With its unique combination of toughness and hardness, this material is commonly used in various industries, from automotive and construction to aerospace and manufacturing. Available in a variety of thicknesses and dimensions, Stainless Steel 410 Sheets offer versatility for a wide range of industrial applications.
- Product Introduction
Stainless Steel 410 sheets are the martensitic warriors of the stainless family, blending exceptional hardness with moderate corrosion resistance. With 11.5–13.5% chromium and 0.15% carbon, these sheets achieve 40–45 HRC post-hardening-ideal for applications demanding wear resistance, thermal stability, and cost efficiency. From hydraulic valve components to coal-fired boiler baffles, 410 sheets thrive where ordinary carbon steel rusts and austenitic grades lack hardness.
Why 410 Outperforms Competing Grades
| Challenge | 410 Sheet | 304 | 420 |
|---|---|---|---|
| Hardness (HRC) | 40–45 (Heat-Treated) | 70–90 HB (Annealed) | 50–55 HRC |
| High-Temp Oxidation | Resists scaling up to 650°C | Fails above 870°C | Resists up to 760°C |
| Cost per Ton | $3.200 | $5.800 | $4.500 |

Fabrication Precision
Heat Treatment Protocol:
Annealing: Heat to 840–900°C, slow cool to 600°C (HB 200 max for machining)
Hardening: Oil quench from 980–1.040°C + temper at 150–370°C (adjust for toughness vs. hardness)
Welding Tips:
Preheat to 200–300°C for thick sections | Use ER410 filler for critical joints
Machining:
Employ high-speed steel (HSS) tools with sulfur-free lubricants | Avoid dwell to prevent work hardening
