Nyob rau hauv cov txheej txheem ntawm Japanese steel cov ntaub ntawv (JIS series), dav dav qauv txheej txheem qib ob muaj nyob ntawm peb ntu:
Thawj ntu qhia cov khoom siv, xws li s (hlau) rau cov hlau thiab f (ferum) rau hlau.
Qhov thib ob ntu sawv cev sib txawv ntawm cov qauv sib txawv, hom, lossis siv, t (raj) rau cov raj, v rau cov nqaj hlau / hlau, c rau kev lom zem, thiab f rau kev lom zem.
Qhov thib peb feem siv cov lej los taw qhia tus lej steel lossis tus lej tsawg lossis cov nqi qis dua ntawm qhov muaj zog. Qee qib kawm kuj suav nrog cov lus tom hav zoov zoo li A, B, lossis C tom qab tus lej los txhais cov qib sib txawv, hom, lossis tuab.
Piv txwv li: SS400-
Thawj s sawv rau hlau,
Qhov s sawv rau "qauv,"
400 qhia txog qhov qis qis qis qis tensile lub zog ntawm 400 MPA,
Zuag qhia tag nrho, nws txhais tau ib qho dav dav qauv hlau nrog lub zog tensile ntawm 400 MPA.
Tom qab tus qauv tseem ceeb ntawm qib (thawj zaug, thiab thib peb ntu), kev kho cov qauv tsim, thiab kho kom sov yuav tau ntxiv raws li xav tau.
- Tus kab mob spc: Sawv cev txias -}} Cov nplooj ntawv hlau steel thiab strips rau kev siv dav dav, sib npaug rau Suav qib Q195-215a. Tus thib peb tsab ntawv c yog lo lus luv rau mob khaub thuas. Thaum kev sim tshuaj Tensile yuav tsum muaj, ntxiv t nyob rau qhov kawg ntawm qib, ua rau nws spcct.
- SPCD: Sawv cev txias - Cov nplooj ntawv hlau steel thiab strips rau Suav qib 08Ar (13237) High {Zoo carbon qauv qauv hlau.
- Spce: Sawv cev txias -} Cov nplooj ntawv hlau steel thiab strips rau Suav qib 08al (5213) tob {}} daim hlau. Thaum tsis - kev laus}}}}}}}}}}}}}} yuav tsum muaj, ntxiv n thaum kawg ntawm qib, ua rau spcen.
