Steels U9A // C85W - piav qhia

Hlau nrog cov ntsiab lus carbon me ntsis siab dua qhov taw tes eutectoid. Nws yog qib steel nrog cov ntsiab lus qis tshaj plaws ntawm tag nrho cov cuab yeej steel siv rau machining. Txawm hais tias nws muaj qhov nyuaj zoo ib yam li cov hlau uas muaj cov ntsiab lus carbon ntau dua, nws muaj qhov ua kom tsis zoo thiab ua kom tsis zoo. N9E muaj kev tiv thaiv ntau dua rau kev cuam tshuam thiab poob siab dua N9, yog li nws raug pom zoo kom siv N9E steel rau cov ntawv thov uas xav tau zoo dua.

Daim ntawv thov

Qhov no alloy yog dav siv rau: Chisels Punches Cutters Ntoo cov cuab yeej ntsia hlau kais

Mechanical thiab lub cev muaj zog

Hardness yog tus yam ntxwv tseem ceeb tshaj plaws hauv qhov no.

Txias

N9 txawv ntawm N9E hauv nws lub peev xwm hardening, zoo li U9 thiab U9A. U9 thiab N9 yog cov hlau sib sib zog nqus, thiab U9A thiab N9E yog cov hlau tawv tawv. Nyob rau hauv cov ntaub ntawv no, nto-hardening steels muaj kev cuam tshuam ntau dua li lawv sib sib zog nqus-hardening counterparts.
