Automotive Mechanical SCM430 Alloy Precision Steel Pipe Cold Drawn Seamless Steel Pipe

Automotive Precision Seamless Alloy Steel Pipe (SCM415 / SCM420 / SCM430 / SCM435 / SCM440)

Material

This product is a precision seamless mechanical steel pipe manufactured from JIS SCM-series chromium–molybdenum (Cr-Mo) alloy steels. These steels are widely used for automotive and high-load mechanical parts because they combine high strength, good hardenability, fatigue resistance, and stable machining performance. Chemical composition requirements for SCM415/420/430/435/440 are defined in JIS G4053.

Specifications

Product type: Precision mechanical seamless steel pipe / tube (hot-finished and/or cold-finished)
Typical OD range: 6–323.8 mm (0.25"–12 3/4")
Typical wall thickness: 1–50 mm (as required by design)
Length: 3–12 m random; fixed length on request
Manufacturing process: hot piercing → hot rolling → cold drawing/cold finishing (optional) → heat treatment (optional) → straightening → NDT/inspection
Supply condition (optional): Annealed / Normalized / Stress-relieved / Quenched & tempered (per requirement)

Key Features

Seamless structure for reliable pressure and fatigue performance
Excellent heat-treat response (carburizing / quenching & tempering / induction hardening depending on grade)
High strength-to-weight ratio for lightweight automotive design
Good machinability for precision turning, drilling, honing, and threading
Stable quality suitable for mass-production components

Our Advantages

“Can you hold tight tolerances for automated assembly?”
We offer cold-finished options with controlled OD/ID consistency, straightness, and surface quality, enabling stable fit-up for bushings, shafts, sleeves, and welded sub-assemblies.
“Can you deliver the exact heat-treatment condition I need?”
We can supply multiple delivery conditions commonly used for mechanical tubes (e.g., hot-finished/cold-finished and normalized/annealed/stress-relieved), and align the condition to your target machining or performance requirements.
“How do you ensure compliance and traceability for automotive programs?”
We provide heat/lot traceability, inspection documentation (e.g., chemical analysis, dimensional reports), and optional NDT (UT/ET) to support consistent qualification and repeatable supply.
