Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov qib steel no suav nrog cov pa roj carbon (c), si), mn), phosphorus (s), leej faj (n). Ntawm no yog ib lub ntsiab lus ntawm lawv qhov tseem ceeb:

Carbon (c): Ua kom muaj zog zog thiab hardness tab sis tuaj yeem txo kev du.
Silicon (si): AIDS hauv DEIGHIDATION thiab tuaj yeem txhim kho lub zog.
Manganese (mn): Txhim kho lub zog thiab hardness.
Phosphorus (p)thiabSulphur (s): Feem ntau tsis xav tau raws li lawv tuaj yeem txo cov qauv sib zog thiab tawv, tab sis lawv cov ntsiab lus txwv tsis pub tsawg hauv cov qib steel.
Nitrogen (n): Tuaj yeem txhim kho lub zog tab sis raug tswj kom tsis txhob muaj embrittlement.
Cov nqi ntawm cov khoom siv alloy xws li Vanadium (V), tendanium (ti), thiab niobium (NB) kuj tseem tuaj yeem ua kom muaj cov qoob loo thiab txhim kho kev ua hlau.

Qhov sib txawv ntawm cov steel qib j 0 h, j2h, jrh, NH, thiab NLH

Q: 1.What yog j {1}} h?

A:This designation indicates that the steel has been tested for impact toughness at {{0}} degree and must meet a minimum impact energy requirement of 27 Joules. Tus "J0" qhia meej qhov ntsuas kub ntawm qhov kev ntsuas qhov kev cuam tshuam tau ua, thiab "H" qhia tias nws yog ntu Hollow.

Q: 2.Qhov yog J2h yog dab tsi?

A: Zoo ib yam li J 0 h, tab sis "J2" Degree thiab yuav tsum tau ua raws li qhov cuam tshuam tsawg kawg ntawm 27 Joules. Qhov no ua rau J2H hlau ntau haum rau siv nyob rau hauv ib puag ncig qhov chaw uas cov khoom yuav tuaj yeem ua nkig.

Q: 3.Qhov yog jrh?

A: Tus "JR" qhia tias cov hlau tau hais txog cov khoom siv ntawm chav tsev ntawm chav sov, muaj kev cuam tshuam tsawg kawg nkaus ntawm 27 joules. Qhov no feem ntau yog siv rau cov qib steel uas tsis tas yuav kuaj ntawm qis dua qhov kub.

Q: 4.Qhov dab tsi NH?

A: Tus "N" nyob rau hauv no cov qauv qhia tau qhia tias cov hlau yog qhov qub los yog dov, uas ua rau cov hlau uas tau nplua. Tus txheej txheem no txhim kho cov hlau txoj kev nruj, tshwj xeeb tshaj yog thaum muaj qhov kub qis dua. Tus "H" dua qhia tias nws yog cov stollow seem, thiab cov hlau yuav tsum tau ua kom muaj kev cuam tshuam tsawg kawg ntawm 40 joules} degree .q: 4. Dab tsi yog NH?

Q: 5.What yog NLH?

A: Zoo ib yam li NH, tab sis nrog "L" qhia tias cov hlau tau sim rau kev cuam tshuam nyuaj ntawm {}} degree thiab yuav tsum tau ua kom muaj kev cuam tshuam tsawg kawg ntawm 27 joules. Qhov no ua rau NLH steel haum rau ib puag ncig txias heev.

Qhov sib txawv ntawm cov qib steel no nyob rau hauv cov kub tshwj xeeb uas lawv tau kuaj rau tej yam kev cuam tshuam thiab lawv cov kev xav tau ntau yam tsawg kawg nkaus. J {{{{0} h thiab j2h yog tsim los siv nyob rau hauv 0 degree}} mus rau chav siv kub. NH thiab NLH yog cov hlau nplej zoo nrog kev txhim kho nruj, ntsuas ntawm -20}}}}} degree raws li, ua rau kev siv nyob rau hauv huab cua ntuj.
