A36 VS S235JR
Cov khoom sib txawv
American standard seamless steel yeeb nkab A36 yog ua los ntawm carbon structural steel, muaj qee yam khoom xws li vanadium, manganese, silicon, thiab tooj liab. Cov khoom siv no muaj qhov zoo weldability thiab manufacturability, thiab tuaj yeem siv los tsim ntau yam qauv engineering. European tus qauv seamless steel yeeb nkab S235JR, ntawm qhov tod tes, yog ua los ntawm kub- dov tsis yog- alloy structural steel, nrog carbon, silicon, manganese, sulfur, thiab phosphorus ua nws cov khoom tseem ceeb. Cov khoom siv no muaj cov ntsiab lus qis dua thiab cov yas zoo, thiab siv dav hauv kev tsim kho, kev tsim tsheb, thiab kev tsim tshuab.

Cov txheej txheem ntau lawm sib txawv
American tus qauv seamless steel yeeb nkab A36 yog tsim los siv lub txias - txheej txheem kos duab, qhov twg hlau yog rhuab mus rau ib tug tej yam kub thiab ces kos los ua ib tug seamless raj. Cov txheej txheem no muab cov khoom siv siab zog thiab corrosion kuj. European txheem seamless steel yeeb nkab S235JR, txawm li cas los xij, yog tsim los siv cov txheej txheem forging, qhov twg hlau molten yog rhuab mus rau qhov kub thiab txias thiab tom qab ntawd forged los ua ib lub raj seamless. Cov txheej txheem no muab cov khoom zoo plasticity thiab toughness.
Daim ntawv thov sib txawv
Vim nws lub zog siab thiab corrosion kuj, American standard seamless steel yeeb nkab A36 yog dav siv nyob rau hauv lub tsev, txuas hniav, shipbuilding, thiab machinery manufacturing. European txheem seamless steel yeeb nkab S235JR muaj zoo plasticity thiab toughness, ua rau nws tsim nyog rau kev tsim kho engineering, kho kom zoo nkauj, thiab kev lag luam. Xaiv cov khoom tsim nyog seamless steel yeeb nkab raws li kev siv tshwj xeeb thiab kev ua tau zoo tuaj yeem txhim kho qhov project zoo thiab kev pabcuam lub neej.
