Lub caij nplooj ntoos hlav steel EN45
EN45 yog manganese caij nplooj ntoos hlav hlau. Qhov ntawd yog hais tias, nws yog cov hlau uas muaj cov ntsiab lus ntawm cov pa roj carbon ntau, cov kab ntawm manganese uas cuam tshuam rau cov hlau cov khoom, thiab feem ntau yog siv rau cov springs (xws li cov ncua kev kawm ntawv ntawm cov tsheb qub). Nws yog tsim rau roj hardening thiab tempering. Thaum siv rau hauv cov roj hardened thiab tempered mob EN45 muaj cov yam ntxwv zoo caij nplooj ntoos hlav. EN45 feem ntau yog siv rau hauv kev lag luam tsheb rau kev tsim thiab kho cov nplooj springs.
Caij nplooj ntoos hlav steel EN47
EN47 yog tsim rau roj hardening thiab tempering. Thaum siv nyob rau hauv cov roj hardened thiab tempered mob EN47 caij nplooj ntoos hlav steel sib txuas cov yam ntxwv caij nplooj ntoos hlav nrog zoo hnav thiab puas kuj. Thaum hardened EN47 muaj zoo heev toughness thiab poob siab kuj uas ua rau nws ib tug haum alloy caij nplooj ntoos hlav steel rau qhov chaw raug kev nyuaj siab, poob siab, thiab kev co.EN47 yog siv dav hauv kev lag luam tsheb thiab hauv ntau daim ntawv thov engineering. Haum rau cov ntawv thov uas xav tau lub zog tensile siab thiab toughness. Cov ntawv thov xws li crankshafts, steering knuckles, gears, spindles, thiab twj.
