Technical Excellence & Customization 

While JIS G3441 covers a range of alloy steel grades (including SCr, SCM, and SNCM series), Tenjan’s expertise lies in tailoring materials to meet specific operational needs. Our custom alloy formulation capabilities allow us to produce tubes with optimized chemical compositions, ensuring enhanced mechanical properties such as higher tensile strength, improved wear resistance, and superior fatigue performance. Whether you require chromium-molybdenum steels for high-temperature applications or nickel-chromium alloys for impact-resistant components, we provide tailored solutions that align with JIS G3441’s stringent requirements.

Key Advantages of Tenjan’s Manufacturing Process 

Precision Cold-Drawing /cold rolling Technology: 

•Achieves tight dimensional tolerances (e.g., outer diameter ±0.1 mm, wall thickness ±10%) and exceptional surface smoothness (Ra ≤ 3.2 μm).

•Enhances grain structure uniformity and mechanical strength through controlled strain hardening.

Superior Material Performance: 

•High yield strength (≥355 MPa) and tensile strength (≥450–980 MPa, depending on grade) for load-bearing components.

•Excellent toughness and fatigue resistance, ideal for dynamic or high-stress applications.

Flexible Heat Treatment Options: 

•Tubes supplied in normalized, annealed, or quenched-and-tempered states to meet specific hardness and ductility requirements.

Quality Assurance & Compliance 

Every batch of Tenjan’s JIS G3441 tubes undergoes rigorous testing to ensure compliance with international standards:

•Chemical Analysis: Verification of alloy elements (Cr, Mo, Ni, etc.) and impurity control (P, S ≤ 0.030%).

•Mechanical Testing: Tensile, hardness, and impact tests to validate performance under simulated operational conditions.

•Non-Destructive Inspection: Ultrasonic or eddy current testing to detect internal or surface defects.

•Certification: Mill test certificates (ISO 9001-compliant) providing full traceability from raw material to finished product.
