S355 na Q355 byombi byerekana ibyuma byubatswe, ariko biva mubipimo bitandukanye kandi bifite itandukaniro mubisobanuro byabo nibisabwa.
S355 Icyuma
Bisanzwe: EN 10025-2 (Iburayi)
Icyiciro: S355
Ibisobanuro: S355 nimbaraga-ndende, ibyuma-byubatswe byubatswe hamwe nimbaraga ntoya ya 355 MPa. Bikunze gukoreshwa mubwubatsi nuburyo bukoreshwa muburyo bwiza bwo gusudira no gukora neza.
Ibyiciro rusange:
S355JR: Ibyuma rusange byubatswe bifite ingufu nkeya zingana na 355 MPa ningufu za 27J mubushyuhe bwicyumba.
S355J0: Ingufu ntoya ya 27J kuri 0 ° C.
S355J2: Ingufu ntoya ya 27J kuri -20 ° C.
Q355 Icyuma
Igipimo: GB / T 1591 (Igishinwa)
Icyiciro: Q355
Ibisobanuro: Q355 nicyuma gikomeye cyubaka ibyuma bifite ingufu nkeya zingana na 355 MPa, bisa na S355. "Q" bisobanura "Qu" (ingingo yumusaruro), naho "355" bivuga imbaraga nke zumusaruro muri MPa.
Ibyiciro rusange:
Q355B: Ingufu ntoya ya 27J kuri 20 ° C.
Q355C: Ingufu ntoya ya 27J kuri 0 ° C.
Q355D: Ingufu ntoya ya 27J kuri -20 ° C.
