The S275JR EN 10025 Steel Hot Finished Square Pipe is a low carbon grade structural steel. This grade of high tensile strength structural S275JR RHS and Hot Finished Circular Hollow Section steel is one that could be readily welded to other weldable steel grades as well.

S275JR钢板为一般碳素结构钢，此类钢与我国GB/T700和GB/T1591所列钢号相近似，也为工程与结构钢用碳素结构钢和低合金结构钢，通常不经热处理交货。

This page is mainly introduced the S275JR Datasheet, including chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc.

For typical Circular Hollow Sections (CHS) the geometric properties of the cross-section are defined in the following standards: The geometric properties that fully define the cross-section are: external diameter D and wall thickness t. The notation is defined in EN1993-1-1 §1.7 which is reproduced in the figure above.
