S355K2+N High Strength Low Alloy HSLA Steel
S355K2+N siab zog steel ntawv yog cov khoom siv hlau uas muaj nyob hauv European tus qauv EN 10025-2. S355K2+N qis alloy steel ntawv muaj cov khoom siv zoo thiab ua haujlwm ntev thiab tsim nyog rau ntau yam kev tsim vaj tsev thiab kev tsim kho.
S355K2+N siab tensile steel phaj qhov twg S sawv cev rau cov qauv hlau, 355 yog lub zog tawm los ntawm cov hlau phaj, thiab K2 sawv cev rau qhov kev ua tau zoo ntawm cov hlau phaj, uas yog, thaum lub phaj hlau cuam tshuam ntawm { {4}} degrees, qhov cuam tshuam lub zog tsis tsawg dua 40J. N txhais tau hais tias kev xa khoom ntawm cov hlau phaj yog normalizing.
S355K2+N siab zog steel phaj tuaj yeem siv los tsim: drilling rigs, hluav taws xob shovels, hluav taws xob log pob tseg tsheb, mining tsheb, excavators, loaders, bulldozers, ntau yam cranes, thee mine hydraulic txhawb nqa thiab lwm yam machinery rau mining thiab ntau yam engineering kev tsim kho. Cov khoom siv thiab lwm yam khoom siv.
