Materials and Characteristics:

- Material: S355J2H is a low-alloy high-strength steel with good mechanical and welding properties.

- Characteristics: With high yield strength (minimum yield strength is 355MPa) and tensile strength, it is suitable for structural parts that can withstand large loads. Its chemical composition and mechanical properties meet the EN10219 standard.

Impact performance: The requirement is -20℃ impact work above 27J, with good plasticity and impact toughness.

Production process:

- Production process: Cold bending welding process is usually used to ensure the uniformity and strength of the steel.

- Coating: The common coating is black tube (uncoated), which is suitable for general structural purposes.

Inspection method: including spectral analysis, ultrasonic flaw detection, eddy current flaw detection, etc., to ensure that the product is defect-free.
