Warranty muag ntawm 30CrMo alloy steel yeeb nkab chaw tsim tshuaj paus
30CrMo alloy steel yeeb nkab muaj cov ntsiab lus carbon ntawm 0.26 ~ 0.34, silicon ntsiab lus ntawm 0.17 ~ 0.37, manganese cov ntsiab lus ntawm 0.40 ~ 0.70, molybdenum cov ntsiab lus ntawm 0.15 ~ 0.25, chromium ntsiab lus ntawm 0.80 ~ 1.10. Muaj ob qho tib si kev sib raug zoo thiab qhov sib txawv ntawm cov yeeb nkab alloy thiab seamless yeeb nkab, uas tsis tuaj yeem tsis meej pem. Alloy yeeb nkab yog txhais raws li cov yeeb nkab steel raws li cov khoom siv (xws li cov khoom siv). Raws li lub npe qhia, nws yog cov yeeb nkab ua los ntawm alloy; Seamless yeeb nkab yog txhais raws li cov txheej txheem ntawm cov yeeb nkab steel (seamless seam). Dab tsi yog qhov txawv ntawm cov yeeb nkab seamless yog seamless yeeb nkab, nrog rau ncaj seam welded yeeb nkab thiab kauv yeeb nkab. 35CrMo, 16-50mn, 27SiMn, 40Cr, Cr5Mo 12Cr1MoV 12Cr1MoVG 15CrMo 15CrMoG 15CrMoV 13CrMo44 T91 27SiMn 25CrMo 30CrMo 40CrMo9 35CrMo9 15CrMo9 p22.91 ua.

Qib steel, abbreviated li steel qib, yog lub npe ntawm txhua yam khoom steel. Nws yog ib hom lus uas tib neeg to taub steel. Hauv Suav teb, cov cim nruj feem ntau qhia los ntawm kev sib xyaw ntawm Suav Pinyin tsiaj ntawv, cov cim tshuaj lom neeg thiab cov lej Arabic.
Tom ntej no, peb yuav qhia lub ntsiab lus ntawm cov ntsiab lus thiab cov cim hauv cov hlau alloy
Ob tus lej thaum pib ntawm qib steel sawv cev rau cov ntsiab lus carbon ntawm cov hlau, qhia tias yog ob peb txhiab ntawm cov ntsiab lus nruab nrab carbon, xws li 40Cr.
Lub ntsiab alloying ntsiab nyob rau hauv steel, tshwj tsis yog rau ib tug neeg microalloyed ntsiab, feem ntau qhia nyob rau hauv ob peb feem pua. Thaum qhov nruab nrab alloy cov ntsiab lus tsawg dua 1.5%, hauv qib steel
Feem ntau, tsuas yog lub cim cim cim, tab sis cov ntsiab lus tsis raug cim. Txawm li cas los xij, yog tias nws yooj yim kom tsis meej pem hauv qhov xwm txheej tshwj xeeb, tus lej "1" kuj tuaj yeem raug cim tom qab lub cim cim,
Piv txwv li, rau cov qib steel "12CrMoV" thiab "12Cr1MoV", cov ntsiab lus chromium ntawm lub qub yog 0.4-0.6%, thiab cov tom kawg yog 0.9-1.2%, thiab lwm yam khoom yog tib yam.
Thaum cov ntsiab lus nruab nrab ntawm cov ntsiab lus alloy yog ≥ 1.5%, ≥ 2.5%, ≥ 3.5% ... Cov ntsiab lus yuav tsum tau qhia tom qab lub cim cim, uas tuaj yeem qhia tau tias yog 2 thiab 3 raws li.
hlau alloy
Alloy (2 daim)
Lwm yam piv txwv, 18Cr2Ni4WA.
Vanadium V, titanium Ti, aluminium Al, boron B, tsis tshua muaj ntiaj teb RE thiab lwm yam hlau alloy hauv cov hlau yog cov khoom siv microalloyed. Txawm hais tias cov ntsiab lus tsawg heev, lawv yuav tsum tseem nyob hauv qib steel
Mark. Piv txwv li, hauv 20mnvb steel, vanadium yog 0.07-0.12% thiab boron yog 0.001-0.005%.
Cov hlau zoo yuav tsum raug cim nrog "a" tom kawg ntawm qib steel kom paub qhov txawv ntawm cov hlau zoo.
Rau alloy structural steel rau lub hom phiaj tshwj xeeb, qib steel yog ua ntej los ntawm (los yog cov lus tom qab) los sawv cev rau lub cim ntawm lub hom phiaj ntawm cov hlau. Piv txwv li, 30CrMnSi steel rau riveting ntsia hlau,
Cov qib steel yog qhia raws li ml30crmnsi.
Rau cov kws tshaj lij uas tsis tshua muaj alloy siab zog steel, nws yuav tsum tau qhia thaum kawg ntawm qib steel. Piv txwv li, 16Mn steel, tshwj xeeb steel siv rau txuas hniav yog "16Mnq", chav
Qhov tshwj xeeb steel qib ntawm girder yog "16MnL", thiab cov qib tshwj xeeb steel ntawm lub nkoj siab yog "16MnR".
