Q460E high-strength steel phaj yog cov khoom tseem ceeb uas tau siv dav hauv kev tsim kho, choj, nkoj, tsheb thiab lwm yam, thiab nws cov khoom siv zoo heev thiab kev ua haujlwm tau txais kev saib xyuas dav.
Cov tshuaj muaj pes tsawg leeg ntawm Q460E siab zog steel phaj yog tsim los ntawm hlau, carbon, manganese, phosphorus, sulfur thiab lwm yam khoom. Ntawm lawv, hlau yog lub ntsiab ntawm cov hlau, carbon yog lub ntsiab tseem ceeb uas cuam tshuam rau cov khoom siv thiab kev ua haujlwm ntawm cov hlau. Manganese, phosphorus, sulfur thiab lwm yam khoom muaj qee yam cuam tshuam rau cov khoom siv kho tshuab thiab kev ua haujlwm ntawm cov hlau.
