P460NL1 steel phaj yog ib hom uas tsis tshua muaj alloy high-strength steel qauv, cov khoom tseem ceeb muaj xws li carbon, silicon, manganese, phosphorus, sulfur, nitrogen thiab lwm yam khoom. Ntawm lawv, cov pa roj carbon yog ib qho tseem ceeb tshaj plaws hauv cov hlau, uas tuaj yeem ua rau lub zog thiab tawv tawv ntawm cov hlau, tab sis tib lub sijhawm yuav txo cov plasticity thiab toughness ntawm hlau. Silicon thiab manganese yog ib qho tseem ceeb alloying ntsiab nyob rau hauv steel, lawv muaj peev xwm refine lub koom haum qauv ntawm steel, txhim kho lub zog thiab hardness ntawm hlau. Phosphorus thiab sulfur yog cov teeb meem hauv cov hlau, lawv ua rau cov brittleness thiab txo cov tawv tawv ntawm cov hlau. Nitrogen yog ib yam khoom uas muaj cov tshuaj ntxiv dag zog thiab kev laus zog, uas tuaj yeem ua rau kom muaj zog thiab tawv tawv ntawm cov hlau.
P460NL1 steel phaj muaj cov cuab yeej zoo heev, nws lub zog tensile, lub zog tawm los, elongation thiab cuam tshuam toughness siab. Ntawm chav tsev kub, lub zog tensile ntawm P460NL1 steel phaj feem ntau yog nruab nrab ntawm 400-650MPa, lub zog tawm los yog feem ntau ntawm 270-400MPa, qhov elongation feem ntau yog nyob nruab nrab ntawm 18%-25%, thiab feem ntau toughness yog nyob nruab nrab ntawm 80-100J/cm². Thaum qhov kub thiab txias, cov khoom siv kho tshuab ntawm P460NL1 steel phaj yuav raug cuam tshuam rau qee qhov, tab sis tseem muaj peev xwm tswj tau qib siab.
P460NL1 steel phaj yog dav siv hauv kev tsim kho, choj, nkoj, tsheb thiab lwm yam. Hauv kev tsim kho, P460NL1 steel phaj tuaj yeem siv los tsim cov qauv thiab cov khoom ntawm cov tsev siab, txuas hniav, arenas thiab lwm lub tsev loj; nyob rau hauv lub tshav pob ntawm cov nkoj, P460NL1 steel phaj tuaj yeem siv los tsim cov nkoj nkoj, cabins, decks thiab lwm yam khoom siv; Hauv kev lag luam tsheb, P460NL1 steel phaj tuaj yeem siv los tsim tsheb chassis, thav duab, lub cev tsheb thiab lwm yam khoom siv. Tsis tas li ntawd, P460NL1 steel phaj tuaj yeem siv los tsim ntau lub nkoj siab, boilers, pipelines thiab lwm yam khoom tshwj xeeb.
