410 is a basic martensitic stainless steel (≈12% Cr class) designed for applications that need higher strength, wear resistance, and moderate corrosion resistance compared with carbon steels. It is commonly supplied annealed or quenched & tempered to reach targeted hardness/strength levels for machined automotive components.
Product type: Martensitic stainless steel seamless pipe / tube
Typical supply condition: Annealed / Quenched & Tempered (as required)
Typical size range (customizable):
OD: 6–219 mm (or per drawing)
WT: 1–30 mm (or per drawing)
Length: fixed or random (commonly up to 6 m / 12 m)
End type: Plain / Beveled / Threaded (optional)
Surface: Pickled, polished, bright annealed, or as specified
Inspection/Documentation (optional): EN 10204 3.1 MTC, dimensional report, PMI, NDT
Heat-treatable strength: Can be hardened and tempered for demanding mechanical loads.
Wear resistance: Suitable for parts facing friction/abrasion (shafts, bushings, sleeves).
Moderate corrosion resistance: Performs well in mild atmospheres/fresh water; best when hardened and finished smooth.
Magnetic (ferromagnetic): Typical of straight-chromium martensitic grades.
Temperature capability (application-dependent): Often referenced with scaling resistance around ~650°C (typical guidance varies by condition and environment).
Chemistry & traceability you can audit
Each heat can be supplied with MTC (EN 10204 3.1) and full heat/lot traceability.
Optional PMI verification to confirm grade identity before machining or assembly.
Dimensional precision for machining yield
Automotive buyers often prioritize OD/WT consistency, straightness, and ovality to reduce scrap and improve CNC efficiency.
We support tight dimensional control with 100% dimensional checks (and reporting when requested).
Heat-treatment control & joining guidance
Martensitic stainless steels are performance-sensitive: hardness/strength must match the application, and welding requires correct procedures.
We can supply to targeted conditions (annealed or Q&T) and provide guidance such as preheating and post-weld heat treatment practices for 410 to reduce cracking risk.

A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock,
it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
