What This Product Is For
Grade 410 is the basic martensitic stainless steel, written as 1.4006 or X12Cr13 under EN and UNS S41000 under the UNS system. AISI 410 is heat treatable, and it is often supplied in the hardened but still machinable condition for applications that need high strength together with moderate heat and corrosion resistance. Chromium sits between 11.50 and 13.50 percent.
Key Benefits
- Heat treatable, so strength and hardness can be set to the part rather than to the stock
- Often supplied hardened but still machinable, which removes a separate treatment step
- High strength with moderate heat and corrosion resistance in one grade
- Round bar to 900 mm and square bar to 500 x 500 mm
- Three international designations quoted so export documentation matches the buyer standard
Who It Is For
- Valve and pump manufacturers needing a hardenable stainless
- Machine shops producing wear resistant components
- Fastener makers working with martensitic grades
- Buyers quoting EN 1.4006 or UNS S41000
Problems It Solves
- Austenitic grades that cannot be hardened for wear duty
- Extra lead time when bar has to be sent out for hardening before machining
- Cross reference confusion between 410, 1.4006, X12Cr13 and S41000
- Sourcing large diameter martensitic bar
Application Scenarios
- Valve components and seats needing hardness and wear resistance
- Shafts and pins in mildly corrosive service
- Fasteners that must be hardened after forming
- Machined parts where moderate corrosion resistance is enough

Materials
- 410 martensitic stainless steel
Manufacturing Process
- Hot rolling
- Cold drawing
- Hardening and tempering
- Machining
Quality Control
- Chromium confirmed within 11.50 to 13.50 percent
- Carbon checked within the 0.08 to 0.15 percent band
- Hardness recorded where the bar is supplied in the hardened condition
- Diameter and length measured before bundling
Customisation Options
- Round or square profile within the published size range
- Supplied annealed or in the hardened and machinable condition
- Length cut anywhere between 1000 mm and 12000 mm
Use Guide
- Order in the hardened and machinable condition when the finished part needs strength without a further treatment
- Expect moderate rather than high corrosion resistance, so avoid chloride service
- Machine before final hardening where a high hardness is required
- Quote 1.4006, X12Cr13 or S41000 for European and international documentation
How It Compares With the Alternatives
| 304 stainless bar | 410 can be hardened by heat treatment where 304 cannot, but 304 offers much better corrosion resistance |
|---|---|
| 301 stainless bar | 301 gains strength only by cold working, while 410 is hardenable by heat treatment |
| 420 stainless bar | 410 is the basic martensitic grade, with higher carbon martensitic grades used where more hardness is needed |
