S275NL Low Alloy High Strength Steel

 

 

 

 

 

 

 

S275NL is a low - alloy high - strength structural steel under the European standard EN 10025 - 31. It has excellent mechanical properties, low - temperature toughness, and weldability, and is widely used in construction, bridges, offshore engineering, energy, and mechanical manufacturing1. Here is a detailed introduction:

 

Processing and Welding Properties1

S275NL is easy to weld and process. After welding, the joint performance is good, and it is suitable for manufacturing complex structural parts. Its good processing properties include cutting, bending, drilling, etc., which are convenient to meet the diverse engineering requirements.

Application Areas1

Construction and Bridges : It is used for high - rise building frames, load - bearing components, bridge girders, and piers.

Offshore Engineering : It is suitable for offshore platforms and near - shore structures to resist wave, tidal, and ice loads.

Energy Field : It is used for oil and gas pipelines, storage tanks, and liquefied natural gas (LNG) storage tanks.

Mechanical Manufacturing : It is used for key components of heavy - duty equipment such as cranes, steam turbines, and excavators.

Low - Temperature Environment : It is suitable for structural parts in extremely cold conditions, such as low - temperature storage facilities.

Differences from Other Steels1

Compared with other steels in the S275 series (such as S275JR, S275J0, S275J2, S275N), the main difference of S275NL is that it has higher impact toughness requirements, especially in low - temperature environments. The specific impact temperature requirements are as follows: S275JR is at normal temperature; S275J0 is at 0 °C; S275J2 and S275N are at - 20 °C; S275NL is at - 50 °C.
