Re: [MW:12414] Impact test requirement for JO and JR grades in structural fabrication.

Impact test is mandatory for t>6mm, if the material is going for low temperature service.

2011/9/10 arvinda shan <arvindashan@gmail.com>

Dear Experts,

 

For crosshead installation in jetty project, the following materials (37mm) are used.

 

Road way            - S355JO

Crosshead           - S355JR & S275JR

Pipe track            - S355JR

 

As per European structural steel standard EN10025 , for JR grade, Longitudinal charpy V-notch impacts 27J @20 degrees and for JO grade, Longitudinal charpy V-notch impacts 27J @ 0 degrees.

 

We received materials mill certificates w/o impact test.

 

My question is whether impact is mandatory for above grades or any criteria of thickness as per EN10025? Please mention with reference codes.

 

Your valuable suggestions are appreciated.

 

Regards

 

arvinda
