410 Grade Martensitic Stainless Steel Seamless Pipe for Automotive Parts Cold Drawn
410 Stainless Steel Seamless Pipe (Martensitic) for Automotive Parts
Material Overview
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.
Specifications
-
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
Main Features
-
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).
Our Advantages
-
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.
