201 Stainless hlau
Cov ntsiab lus tooj liab: J4>J1>J3>J2>J5.
Cov ntsiab lus carbon: J5>J2>J3>J1>J4.
Hardness: J5, J2> J3> J1> J4.
Qhov kev txiav txim ntawm tus nqi ntawm siab mus rau qis yog: J4> J1> J3> J2, J5.
J1 (Mid Copper): Cov ntsiab lus carbon yog siab dua J4 thiab cov ntsiab lus tooj liab qis dua J4. Nws cov kev ua tau zoo yog tsawg dua J4. Nws yog qhov tsim nyog rau cov duab kos duab sib sib zog nqus thiab cov khoom sib sib zog nqus, xws li cov khoom siv kho kom zoo nkauj, cov khoom siv tu cev, dab dej, cov khoom siv raj, thiab lwm yam.
J2, J5: Cov raj zoo nkauj: Cov raj zoo nkauj yooj yim tseem zoo, vim tias qhov tawv tawv yog siab (ob qho tib si saum 96 °) thiab polishing zoo nkauj dua, tab sis lub raj square lossis lub raj nkhaus (90 °) yog qhov ua rau tawg.
Nyob rau hauv cov nqe lus ntawm lub tiaj tus phaj: vim lub siab hardness, lub board nto yog zoo nkauj, thiab kev kho deg xws li
frosting, polishing thiab plating yog txais. Tab sis qhov teeb meem loj tshaj plaws yog qhov teeb meem khoov, khoov tau yooj yim tawg, thiab qhov zawj yog yooj yim tawg. Txo extensibility.
J3 (Low Copper): Tsim nyog rau cov hniav zoo nkauj. Kev ua haujlwm yooj yim tuaj yeem ua tiav ntawm lub vaj huam sib luag zoo nkauj, tab sis nws tsis tuaj yeem nrog qhov nyuaj me ntsis. Muaj cov lus tawm tswv yim tias lub phaj shearing yog khoov, thiab muaj lub puab seam tom qab tawg (dub titanium, xim phaj series, sanding phaj, tawg, folded nrog puab seam). Cov khoom siv hauv lub dab dej tau sim khoov, 90 degrees, tab sis nws yuav tsis txuas ntxiv.
J4 (High Copper): Nws yog qhov kawg ntawm J series. Nws yog tsim rau lub kaum sab xis me me ntawm cov khoom sib sib zog nqus kos duab. Feem ntau ntawm cov khoom uas xav tau kev sib sib zog nqus ntsev thiab tshuaj tsuag ntsev yuav xaiv nws. Piv txwv li, cov dab dej, cov khoom siv hauv chav ua noj, cov khoom siv hauv chav dej, lub raj mis dej, lub tshuab nqus tsev vacuum, qhov rooj hinges, shackles, thiab lwm yam.
