S355JR yog cov hlau tsis tshua muaj siab muaj zog steel qauv (European tus qauv EN10025).
Tus naj npawb 355 yog hais txog lub zog tawm los ntawm 355MPa.
JR qhia tias tsis muaj cov cai tshwj xeeb rau kev ua kom txias, thiab lwm yam.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm S355JR (% los ntawm qhov hnyav) suav nrog cov hauv qab no:
- Cov pa roj carbon (C): 0.24%
- Silicon (Si): 0.55%
- Manganese (Mn): 1.60%
- Phosphorus (P): 0.035%
- Sulfur (S): 0.035%
- Nitrogen (N): 0.012%
- Copper (Cu): 0.55%
- Chromium (Cr): 0.30%
- Nickel (Ni): 0.30%
- Molybdenum (Mo): 0.10%
Nco tseg:
Rau cov ntsiab lus carbon (C) thiab nominal thickness (t), C los ntawm kev pom zoo thaum seem nrog nominal thickness> 100 hli.
Rau cov khoom ntev, cov ntsiab lus P thiab S tuaj yeem yog 0.005% siab dua.
Yog hais tias cov tshuaj muaj pes tsawg leeg qhia tag nrho cov txhuas (Al) cov ntsiab lus tsawg dua los yog sib npaug rau {{{0}}}.020% los yog acid-soluble Al Less dua los yog sib npaug rau 0.015%, los yog txaus lwm yam nitrogen-binding cov ntsiab lus tam sim no, N siab tshaj plaws tsis siv. Hauv qhov no, cov ntsiab lus nitrogen-binding yuav tsum tau hais hauv daim ntawv tshuaj xyuas
