[MW:5115] Re: INFORMATION

Dear Mr. Parvez,

Your supplier is correct. On this moment all European standards like
DIN & AFNOR become replaced by harmonized European Standards (EN).
For material St.52-3 there are two main specifications: EN 10210 (Hot
finished structural hollow sections of non-alloy and fine-grain
structural steels) and EN 10219 (cold formed welded structural hollow
sections of non-alloy and fine grain structural steels). In these
specifications St. 52.3 is called S355J0H or S355J2H. S = structural
steel; 355 = yield strength of the material; J0 / J2 is temperature of
required Chapry V impact test (J0 = 0°C and J2 = -20°C), H means
Hollow structure.

Best Regards,

Herman Pieper
