en 10025 k2 / en 10025 j2?
hello all
i came across this standard material bs en 10025. i know the "2" which follows j or k signifies the impact temperature(-20 deg c). what does the j or k signify?
check out our whitepaper library.
the principal mechanical property designations are as follows
jr - longitudinal charpy v notch impacts 27j @ room temp
jo - longitudinal charpy v notch impacts 27j @ 0°c
j2 - longitudinal charpy v notch impacts 27j @ -20°c
k2 - longitudinal charpy v notch impacts 27j @ -40°c
g1 - rimming steel
g2 - rimming steel not permitted
g3 - normalised or normalised rolled
g4 - supply condition at manufacturers discretion
m - thermomechanically rolled
l - low temperature impacts @ -50°c
w - weather resistant grades
c - cold forming grade
p - piling grade
