Cov cuab yeej cuab tam rau St 37-2 steel phaj
hlau phajKhoom Taw Qhia
Raws li cov khoom siv carbon steel, ST 37-2 muaj lub zog zoo thiab tawv. Nws lub zog tawm los feem ntau yog nyob nruab nrab ntawm 340-470MPa, thiab nws lub zog tensile nyob nruab nrab ntawm 450-600MPa, uas ua rau nws ua tau zoo thaum raug hnyav thiab cuam tshuam. Tib lub sijhawm, ST37-2 steel kuj muaj cov yas zoo thiab tawv, thiab tuaj yeem tiv taus tawg thiab deformation rau qee yam. Tsis tas li ntawd, nws cov kev ua haujlwm vuam thiab kev ua haujlwm txias ua haujlwm kuj zoo heev, ua rau nws yooj yim rau kev ua thiab cov duab thaum lub sijhawm tsim khoom.
Hais txog cov khoom siv tshuaj, ST37-2 steel yog tsim los ntawm carbon, silicon, manganese, phosphorus, sulfur thiab lwm yam khoom. Ntawm lawv, cov pa roj carbon monoxide yog ib qho tseem ceeb cuam tshuam rau kev ua haujlwm ntawm cov hlau. Cov ntsiab lus carbon ntawm ST37-2 steel yog nruab nrab, uas tsis tsuas yog ua kom lub zog ntawm cov hlau, tab sis kuj zam qhov nce ntawm brittleness tshwm sim los ntawm ntau cov ntsiab lus carbon. Silicon thiab manganese, raws li cov ntsiab lus alloying, tuaj yeem txhim kho lub zog thiab tawv ntawm cov hlau. Raws li impurity ntsiab, phosphorus thiab sulfur yog nruj me ntsis tswj nyob rau hauv ib tug tej yam ntau yam los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm cov hlau. ST37-2 steel feem ntau yog siv rau riveting, bolting, thiab vuam lub hom phiaj. Cov qauv hlau xws li ST37-2 yog siv rau hauv ntau daim ntawv thov, sib txuas cov khoom siv vuam zoo nrog lav lub zog. Muaj ntau qib, thiab kev siv suav nrog kev tsim vaj tsev thiab kev lag luam. High-strength low-alloy tau hloov ntau yam steels (xws li tsheb) qhov twg qhov hnyav txo yog ib qho tseem ceeb tab sis tseem muaj guaranteed lub zog. Siv nyob rau hauv kev tsim kho, underground engineering.
