St37 Hlau Khoom

Cov khoom ntawm St37 steel yog raws li nram no:

St37 steel yog cov hlau tsis muaj cov pa roj carbon tsawg uas paub txog nws txoj kev siv ntau yam thiab ntau yam kev siv. Nyob rau hauv cov nqe lus ntawm mechanical zog, nws muaj zog nruab nrab thiab zoo ductility. Qhov no tso cai rau nws kom yooj yim zoo li tus thiab tsim rau hauv ntau yam qauv thiab cov khoom.

Lub zog tensile ntawm St37 steel feem ntau yog nyob rau hauv thaj tsam ntawm 370-490 MPa, muab lub zog txaus rau ntau daim ntawv thov engineering. Nws lub zog tawm los yog nyob ib ncig ntawm 235 MPa, qhia txog qhov kev ntxhov siab uas cov khoom pib deform plastically.

St37 steel kuj pom zoo weldability. Nws tuaj yeem koom nrog siv ntau yam txheej txheem vuam, ua rau nws tsim nyog rau kev tsim thiab kev tsim kho. Cov welds muaj zog thiab txhim khu kev qha, ua kom muaj kev ncaj ncees ntawm cov qauv.

Nyob rau hauv cov nqe lus ntawm corrosion kuj, St37 steel yog kuj raug rau xeb thaum raug rau ya raws thiab oxygen. Txawm li cas los xij, kev kho kom zoo xws li pleev xim lossis galvanizing tuaj yeem txhim kho nws cov kev tiv thaiv corrosion.

Lub ductility ntawm St37 steel ua rau nws nqus tau lub zog hauv kev ntxhov siab yam tsis muaj kev tawg yooj yim. Cov cuab yeej no yog qhov tseem ceeb hauv cov ntawv thov uas cov khoom yuav raug cuam tshuam los yog dynamic loading.

Lwm tus yam ntxwv tseem ceeb ntawm St37 steel yog nws muaj nyob rau hauv cov ntaub ntawv sib txawv, nrog rau cov nplooj ntawv, daim hlau, tuav, thiab cov raj. Qhov no tso cai rau kev hloov pauv hauv kev tsim thiab kev tsim kho.

Zuag qhia tag nrho, St37 steel kev sib xyaw ua ke ntawm lub zog nruab nrab, zoo ductility, weldability, thiab muaj nyob rau hauv ntau hom ua rau nws muaj kev xaiv nrov hauv ntau qhov kev lag luam, suav nrog kev tsim kho, kev tsim khoom, thiab tsheb. Txawm li cas los xij, nws qhov kev tiv thaiv corrosion yuav tsum muaj kev tiv thaiv tsim nyog los xyuas kom meej lub sijhawm ntev.
