What is BS EN 10210 S275JOH LSAW Steel Pipe

BS EN 10210 S275J0H is a hot-processed hollow structural steel profile manufactured according to BS EN 10210 standard, with various cross-sectional shapes such as round, square, rectangular and oval.

The characteristics of S275J0H material are that the minimum yield strength is 275 MPa when the thickness is not more than 16 mm; the minimum impact energy is at least 27 J at 0℃.

S275J0H is a carbon steel with a steel grade of 1.0149. It has good structural and processing properties. It is mainly used for building structures and can also be used for non-load-bearing components. On the basis of achieving low-cost advantages, it maintains the stability and durability of the structure.

Sepcification:

Wall thickness ≤120mm.

Circular: Outside diameters up to 2500 mm;

Square: Outside dimensions up to 800 mm x 800 mm;

Rectangular: Outside dimensions up to 750 mm x 500 mm;

Elliptical: Outside dimensions up to 500 mm x 250 mm.

Grade designations in BS EN 10210 are assigned in accordance with EN 10027-1 and steel numbers are assigned in accordance with EN 10027-2.

a FN = Rimming steel not permitted;

b It is permissible to exceed the specified values provided that for each increase of 0.001 % N the P, max. content is also reduced by 0.005 %. The N content of the cast analysis, however, shall not be more than 0.012 %;

c The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0.020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document.
