Seamless steel tube chaw tsim tshuaj paus yuav qhia luv luv txog kev faib thiab kev ua haujlwm ntawm carbon steel raj.

1. General carbon steel raj

Feem ntau, steel nrog cov ntsiab lus carbon ntawm ≤0.25% yog hu ua low-carbon steel.Cov qauv annealed ntawm cov pa roj carbon tsawg yog ferrite thiab ib qho me me ntawm pearlite.Nws muaj zog tsawg thiab hardness, zoo plasticity thiab toughness, thiab yog ib qho yooj yim mus kos, stamp, extrude, Forging thiab vuam, uas 20Cr steel yog dav siv.Cov hlau muaj lub zog tshwj xeeb.Tom qab quenching thiab tempering ntawm qhov kub thiab txias, cov hlau no muaj cov cuab yeej zoo txhua yam, qhov kub tsis tshua muaj kev cuam tshuam zoo, thiab kub siab brittleness tsis pom tseeb.

Kev siv:Nyob rau hauv kev lag luam machinery manufacturing, nws yog tsim rau ua welded structural qhov chaw thiab qhov chaw uas tsis muaj kev nyuaj siab tom qab forging, kub stamping thiab machining.Nyob rau hauv chav turbine thiab boiler manufacturing industries, nws yog feem ntau yog siv rau cov kav dej, flanges, thiab lwm yam uas ua hauj lwm nyob rau hauv uas tsis yog-corrosive xov xwm.Headers thiab ntau yam fasteners;kuj tsim nyog rau kev tsim cov khoom me me thiab nruab nrab carburizing thiab carbonitriding qhov chaw hauv tsheb, tsheb laij teb thiab kev tsim khoom siv dav siv, xws li cov khau khiab tes, lub tog raj kheej, thiab gearbox ceev diav rawg ntawm lub tsheb, kis tau tus mob passive zog thiab camshafts ntawm tsheb laij teb, ncua kev sib npaug shafts, sab hauv thiab sab nrauv bushings ntawm balancers, thiab lwm yam.;nyob rau hauv hnyav thiab nruab nrab machinery manufacturing, xws li forged los yog nias khi rods, shackles, levers, tes tsho, fixtures, thiab lwm yam.

2. Tsawg carbon steel raj
Tsawg-carbon steel: Tsawg-carbon steel nrog cov ntsiab lus carbon ntau tshaj 0.15% yog siv rau shafts, bushings, sprockets, thiab ib co yas pwm uas yuav tsum tau siab hardness thiab zoo hnav tsis kam ntawm qhov chaw tom qab carburizing thiab quenching thiab low-temperature tempering.Cheebtsam.Tom qab carburizing thiab quenching thiab low-temperature tempering, cov hlau tsis muaj carbon steel muaj cov qauv ntawm high-carbon martensite nyob rau saum npoo thiab qis-carbon martensite nyob rau hauv nruab nrab, thiaj li yuav xyuas kom meej tias cov nto muaj siab hardness thiab siab hnav tsis kam thaum. qhov chaw muaj siab heev hardness.Zoo zog thiab toughness.Nws yog tsim rau ua tes nres khau, lever shafts, gearbox ceev diav rawg, kis tau tus mob passive zog, camshafts ntawm tsheb laij teb, ncua kev kawm ntawv balancer shafts, sab hauv thiab sab bushes ntawm balancers, tes tsho, fixtures thiab lwm yam.

3. Nruab nrab carbon steel raj
Medium-carbon steel: carbon hlau nrog cov ntsiab lus carbon ntawm 0.25% txog 0.60%.30, 35, 40, 45, 50, 55 thiab lwm qib yog rau nruab nrab-carbon steel.Vim tias cov ntsiab lus pearlite hauv cov hlau nce, nws lub zog thiab hardness siab dua ua ntej.Hardness tuaj yeem nce ntxiv tom qab quenching.Ntawm lawv, 45 steel yog qhov zoo tshaj plaws.45 steel yog lub zog siab nruab nrab-carbon quenched thiab tempered steel, uas muaj qee yam plasticity thiab toughness, thiab kev ua haujlwm zoo.Nws tuaj yeem tau txais cov khoom zoo txhua yam los ntawm quenching thiab tempering kho, tab sis nws cov hardenability tsis zoo.Nws yog siv los tsim cov khoom nrog lub zog siab thiab nruab nrab toughness.Nws feem ntau yog siv nyob rau hauv quenched thiab tempered los yog normalized xeev.Txhawm rau ua kom cov hlau muaj qhov tsim nyog toughness thiab tshem tawm nws qhov kev ntxhov siab, cov hlau yuav tsum tau quenched thiab ces tempered rau hauv sorbite.
