S275J0 cov khoom sib npaug yog dab tsi?
S275J0 steel phaj / ntawv yog nyob rau hauv EN 10025 tus qauv, cov khoom naj npawb yog 1.0143. Cov qib sib npaug ntawm S275J0 steel yogDIN 17100 St 44-3 U, NFA 35-501 E 28-3, UNI 7070 Fe 430 C, BS 4360 43 C, UNE 36.080 AE 275 C, ASTM A 578 Gr. 70
Qhov txawv ntawm S275 JR thiab J0 yog dab tsi?
S275 J0 steel has a guarantee of resilience at 0°C> 27J, while s275JR steel has, when required, a guarantee of resilience at a temperature greater than 20°C> 27J.
Qhov txawv ntawm A36 thiab S275J0 yog dab tsi?
ASTM A36 muaj nruab nrab corrosion kuj vim nws cov ntsiab lus carbon tsawg. Txawm li cas los xij, nws tsis pom zoo siv rau hauv ib puag ncig marine, vim nws yuav tsum tau kho sai sai.S275JR, ntawm qhov tod tes, muaj kev tiv thaiv corrosion zoo dua vim nws cov ntsiab lus ntau dua manganese.
