201 Stainless Hlau
Cov ntsiab lus tooj liab: J4> J1> J3> J2> J5.
Cov ntsiab lus carbon: J5> J2> J3> J1> J4.
Hardness kev npaj: J5, J2> J3> J1> J4.
Qhov kev txiav txim ntawm cov nqi los ntawm qhov siab rau qis yog: J4> J3> J3> J2, J5.
J1 (Mid tooj liab): Cov pa roj carbon: siab dua me ntsis J4 thiab cov ntsiab lus tooj liab yog qis dua J4. Nws kev ua tau zoo yog tsawg dua tshaj li. Nws yog qhov haum rau cov duab ntiav thiab sib sib zog nqus cov khoom lag luam, xws li cov khoom dai, huv si, khoom raj, khoom raj, khoom raj.
J2, J5: Cov leeg dai kom zoo nkauj yog tseem zoo nkauj yog qhov siab dua (tab sis lub raj loj) lossis cov raj nkhaus (90 °) yog luag mus rau bursting.
Nyob rau hauv cov nqe lus ntawm tiaj tiaj phaj: Vim tias lub siab tawv, Pawg Thawj Coj Zoo nkauj, thiab kev kho deg xws li
Frosting, polishing thiab plating yog siv tau. Tab sis qhov teeb meem loj tshaj plaws yog qhov teeb meem khoov, cov khoov yog yooj yim tawg, thiab qhov zawj yog qhov yooj yim tawg. Tsis zoo.
J3 (Tsawg tooj tooj): haum rau kev dai cov hlua. Kev ua tau yooj yim tuaj yeem ua tiav ntawm lub vaj huam sib luag zoo nkauj, tab sis nws tsis muaj peev xwm nrog kev nyuaj me ntsis. Muaj cov lus qhia tias cov ntaub qhwv ntsej muag yog khoov, thiab muaj lub ntsej muag sab hauv tom qab tawg (pob zeb phaj sab hauv, tawg, folded tawm nrog sab hauv). Cov khoom siv tog tau raug sim los khoov, 90 degrees, tab sis nws yuav tsis txuas ntxiv.
J4 (HIGHPER): Nws yog qhov siab dua ntawm J koob. Nws yog qhov haum rau cov hom me me ntawm cov khoom sib sib sib zog nqus. Feem ntau ntawm cov khoom lag luam uas yuav tsum muaj ntsev tob thiab ntsev kuaj tshuaj yuav xaiv nws. Piv txwv, tog, cov tais diav chav ua noj, cov khoom da dej, cov dej hluav taws xob, lub tshuab nqus tsev, rooj zaum, thiab lwm yam.
