ST42 Carbon Steel Pipe: Technical Overview & Applications
Mechanical Properties
ST42 carbon steel pipe exhibits a minimum tensile strength of 420 MPa (42 kgf/mm²), meeting stringent performance criteria for industrial usage.
Standard Compliance
As a German standard seamless steel pipe, ST42 conforms to DIN 1629 specifications, governing material composition and manufacturing processes for general-purpose applications.
Key Characteristics
- Material Composition: Fabricated from non-alloy carbon structural steel (common grades: St37, St44, St52)
- Production Method: Hot-rolled or cold-drawn seamless manufacturing
- Primary Applications:
- Fluid transportation systems (water, oil, gas)
- Structural components in machinery and construction
- Low-to-medium pressure pipeline networks
Industrial Advantages
- Cost-Efficiency: Optimized balance of strength and affordability due to standardized carbon steel composition.
- Versatility: Suitable for welding, machining, and forming processes.
- Corrosion Management: Often paired with protective coatings (e.g., galvanization, epoxy) for enhanced durability in harsh environments.
Technical Specifications
- Dimensions: 6-600 mm OD, wall thickness 1.0-50 mm (customizable per EN 10220)
- Pressure Rating: PN10-PN40, adaptable to project-specific requirements
- Certifications: Available with 3.1B/3.2 material certificates and EN 10204 compliance
This material is predominantly utilized in European and global markets for infrastructure projects requiring reliable pressure integrity and structural stability.
