JIS-SUM 12
| C(%) | Mn(%) | P(%) | S(%) |
|---|---|---|---|
| 0.08-0.13 | 0.6-0.9 | Tsawg dua lossis sib npaug rau 0.04 | 0.08-0.13 |
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm JIS SUM12 steel yog nws cov tshuaj muaj pes tsawg leeg. Nws muaj ib qho kev sib xyaw ua ke ntawm cov ntsiab lus xws li carbon, manganese, sulfur, thiab phosphorus. Cov ntsiab lus carbon muab cov hlau nws lub zog thiab hardness, thaum manganese txhim khu nws toughness thiab hardenability. Sulfur thiab phosphorus yog tam sim no nyob rau hauv cov nqi tswj los txhim kho machinability.
Hais txog cov khoom siv kho tshuab, JIS SUM12 steel muaj lub zog tensile siab thiab lub zog tawm los. Qhov no ua rau nws haum rau cov ntawv thov uas yuav tsum muaj lub zog thiab kav ntev. Cov hlau kuj muaj qhov zoo ductility, cia nws deformed yam tsis muaj cracking yooj yim.
Lub machinability ntawm JIS SUM12 steel yog ib qho ntawm nws qhov zoo. Nws tuaj yeem ua tau yooj yim machined siv ntau yam cuab yeej thiab cov txheej txheem, txo cov sij hawm tsim khoom thiab cov nqi. Lub xub ntiag ntawm leej faj nyob rau hauv cov hlau cov ntaub ntawv manganese sulfide inclusions, uas ua raws li chip breakers thaum lub sij hawm machining, ua rau nws yooj yim rau txiav thiab zoo li.
JIS SUM12 steel yog muaj nyob rau hauv ntau hom xws li tuav, xov hlau, thiab ntawv. Qhov no tso cai rau kev hloov pauv hauv kev tsim thiab tsim khoom, ua rau cov engineers thiab cov tuam ntxhab xaiv cov ntawv tsim nyog tshaj plaws rau lawv cov kev siv tshwj xeeb.
Cov hlau no feem ntau siv rau hauv kev tsim khoom ntawm ntau yam xws li cov ntsia hlau, bolts, ceev, thiab cov ncej. Nws kuj yog siv nyob rau hauv kev lag luam automotive rau qhov chaw xws li lub zog thiab cov khoom sib kis. Tsis tas li ntawd, JIS SUM12 steel tuaj yeem pom nyob rau hauv kev tsim kho kev lag luam rau kev siv xws li fasteners thiab cov khoom siv.
Qhov zoo ntawm JIS SUM12 steel yog xyuas los ntawm kev tswj xyuas nruj. Cov neeg tsim khoom ua raws li JIS (Japanese Industrial Standards) specifications los xyuas kom meej tias cov hlau ua tau raws li qhov yuav tsum tau muaj tshuaj lom neeg muaj pes tsawg leeg, txhua yam khoom, thiab qhov ntev ntev.
Nyob rau hauv xaus, JIS SUM12 steel yog ib tug txhim khu kev qha thiab ntau yam khoom nrog zoo heev machinability thiab txhua yam khoom. Nws qhov tshwj xeeb ua ke ntawm cov yam ntxwv ua rau nws muaj kev xaiv nrov rau ntau yam kev siv hauv kev lag luam sib txawv. Txawm hais tias nws yog rau precision machining lossis cov khoom siv, JIS SUM12 steel muaj kev ua tau zoo thiab zoo.
