Product Introduction

S275JR Welded Pipe Description

S275JR is a European low alloy high-strength structural steel, belonging to the EN 10025-2 standard grade. The material is widely used in various engineering structures and equipment manufacturing, such as bridges, buildings, ships, vehicles, heavy machinery and so on. Due to its excellent mechanical properties and welding properties, S275JR performs well in a variety of complex environments and is able to withstand heavy loads and strong impacts.

Advantages

‌Excellent welding performance‌

Low carbon content and controllable sulfur and phosphorus content (P≤0.035%, S≤0.035%) greatly reduce the risk of hot cracking and support conventional welding without preheating‌.

‌Wide processing adaptability‌

High plasticity (elongation ≥21%) facilitates cold bending and stamping, suitable for complex structure processing‌.

‌Balance of economy and strength‌

The strength is significantly higher than that of ordinary carbon steel (such as Q235), and the unit cost is lower than that of special alloy steel, with outstanding cost performance‌.

‌Optimized weather resistance‌

The copper content is ≤0.55%, and the trace elements of chromium/nickel are used to improve the ability to resist atmospheric corrosion‌.

Applications

Buildings and Infrastructure

‌Steel Structure Frame‌:
The beam-column support system of industrial plants and storage and logistics centers uses its bending resistance to carry roof loads.

Energy and Transportation Equipment

‌Wind Power Foundation Components‌:
Tower connectors and base brackets meet the fatigue resistance requirements under long-term wind vibration loads (fatigue strength ≥ 200MPa).
‌Vehicle Chassis and Shelves‌:
Light truck structural parts and logistics transportation equipment frames to adapt to dynamic load impact.

Industrial Equipment

‌Mechanical Protective Covers and Brackets‌:
Protective structures for food processing lines and automation equipment, taking into account both strength and welding convenience.
‌Low-pressure Storage Tanks‌:
Non-high-risk liquid storage tanks are more economical than special steels for pressure vessels.
