12CrNi2 alloy structural seamless steel yeeb nkab yog ib yam ntawm cov qib siab carburized steel nrog cov khoom zoo txhua yam.
Cov tshuaj muaj pes tsawg leeg ntawm 12CrNi2 structural seamless steel yeeb nkab muaj xws li carbon, silicon, manganese, sulfur, phosphorus, chromium, nickel thiab tooj liab. Nws cov khoom muaj xws li tensile lub zog, yield zog, elongation, cheeb tsam shrinkage, cuam tshuam lub zog thiab cuam tshuam tus nqi toughness. tos. Cov kev kho cua sov tshwj xeeb rau cov yeeb nkab steel no yog quenching thiab tempering, qhov chaw quenching kub yog 860 degree rau thawj zaug thiab 780 degree rau zaum ob, dej-txias lossis roj-txias; tempering kub yog 200 degree, dej-txias los yog cua-txias.
12CrNi2 alloy structural seamless steel yeeb nkab yog tsuas yog siv los tsim cov khoom uas yuav tsum tau muaj zog dua thiab toughness, xws li lub zog, shafts, piston pins, thiab lwm yam.
