S355J2H Square Pipe,S355J2H hollow sections,S355J2H

 

S355J2H Square Pipe,S355J2H hollow sections, S355J2H Factory

Adopt standard: S355J2H steel EN10210-1

 

The number of this European Standard(EN 10210)

The symbol S is structural steel, 275 for the minimum yield strength in thickness not greater than 16mm.

The Symbol J and number 0 or 2 mean for the qualities with specified impact properties at 0℃and -20℃respectively.

The capital letter H indicates hollow sections.

1)The deoxidation methods are designated as follows:

FF-Full killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0.020% total Al, or 0.015% soluble Al).

2)QS-quality steel.

3)It is permissible to exceed the specified values provided that for each increase of 0.001%N the P max content will be reduced by 0.005%,the N content of the ladle analysis ,however,shall not be more than 0.012%

4)The max. 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 Inspection Document.
