Cov yam ntxwv thiab kev siv ntawm 4140 steel: lub zog, siab hardenability, zoo toughness, me me deformation thaum lub sij hawm quenching, siab creep kuj thiab ntev kub kub kuj. Nws yog siv los ua forgings uas yuav tsum tau muaj zog dua thiab loj dua quench seem tshaj 35CrMo steel, xws li loj locomotive traction gears, supercharger tsav gears, rear qag, txuas rods thiab caij nplooj ntoos hlav clips nrog hnyav loads, thiab kuj yuav siv tau rau sib sib zog nqus roj zoo drilling yeeb nkab pob qij txha thiab khaws cia cov cuab yeej hauv qab no 2000 m. Nws tuaj yeem siv los ua bolts, screws, studs, ceev thiab lwm yam fasteners.
Vim nws zoo heev toughness, hnav tsis kam, cuam tshuam tsis kam thiab siab qaug zog, nws yog dav siv nyob rau hauv ntau industries.
