Accreditation Administration System:
EN10025_2 S355JR kind of Low alloy structual steel plate which is intended for manufacture the plants of
factory ,the common constructure and construction machinery and equipment.Usually this grade would be
signed as S355JR+N or S355JR N,it means these plates shall be need Normalized delivery condition,it is
requested from customers.
Ultrasonic Test shall be carried out according to EN10025_1.For the impacting test,it indicates by JR,J0,J2
and K2.
JR means at room temperature with minimum impact energy 27 J;
J0 means at 0 centidegree temperature with minimum impact energy 27 J;
J2 means at -20 centidegree temperature with minimum impact energy 27 J;
K2 means at -40 centidegree temperature with minimum impact energy 40 J.
Now we give you the analysis of these grades as belows:
