Khoom Description

SS400 thiab SM490 yog ob feem ntau siv cov hlau hauv ntau qhov kev lag luam. Txawm hais tias ob qho tib si cov hlau no tau qhuas rau lawv tus kheej txoj hauv kev, lawv txawv ntawm ib leeg ntawm cov ntsiab lus, cov yam ntxwv thiab thaj chaw ntawm daim ntawv thov.

Ntawm qhov tod tes, SM490 steel yog lub zog siab, qis alloy steel. Nws muaj pes tsawg leeg muaj xws li npib tsib xee, chromium, thiab molybdenum, uas txhim kho nws lub zog zog. SM490 steel yog dav siv hauv kev tsim kho, choj tsev, thiab lwm yam kev siv hnyav uas yuav tsum tau muaj zog thiab kav ntev.

Ob hom hlau no muaj lawv qhov tshwj xeeb ntawm qhov zoo thiab kev siv. SS400 steel yog qhov zoo tagnrho rau kev siv cov qauv thiab vuam, thaum SM490 steel yog nyiam rau cov haujlwm hnyav uas muaj zog thiab ua haujlwm ntev yog qhov tseem ceeb. Nws yog ib qho tsim nyog sau cia tias ob hom hlau muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv taus ib puag ncig hnyav, ua rau lawv muaj kev ntseeg siab rau ntau qhov kev lag luam.

H seem steel yog ib hom tshiab ntawm kev lag luam tsim steel.Cov qauv ntawm H-beam steel yog kev lag luam thiab tsim nyog, thiab cov cuab yeej siv tau zoo. Thaum dov, qhov txuas ntxiv ntawm txhua lub ntsiab lus ntawm ntu yog sib xws, thiab kev ntxhov siab sab hauv me me. Piv nrog rau cov hlau I-beam zoo tib yam, nws muaj qhov zoo ntawm qhov loj me me, lub teeb yuag, thiab txuag cov hlau, uas tuaj yeem txo cov qauv ntawm lub tsev los ntawm 30-40%. sab ceg yog lub kaum sab xis, ua ke rau hauv cov khoom, tuaj yeem txuag vuam, riveting kev ua haujlwm ntawm 25% feem ntau yog siv rau hauv cov tsev loj (xws li cov chaw tsim khoom, cov tsev siab siab, thiab lwm yam) yuav tsum tau muaj peev xwm loj thiab zoo seem stability, xws li zoo li choj, nkoj, nqa thiab tsheb thauj mus los machinery, cov khoom siv hauv paus, kev txhawb nqa, lub hauv paus pawg, thiab lwm yam.
