Koj puas paub txog seamless boiler raj 20G thiab SA-210C (25MnG)?

20G yog qib steel teev nyob rau hauv GB / T5310 (cov qhab nia txawv teb chaws: st45.8 hauv lub teb chaws Yelemees, STB42 hauv Nyiv, SA106B hauv Tebchaws Meskas), thiab yog cov hlau feem ntau siv rau boiler steel kav. Nws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab yog tib yam li cov ntawm 20 daim hlau. Cov hlau no muaj qee qhov chaw sov thiab nruab nrab kub siab zog, qis carbon cov ntsiab lus, zoo plasticity thiab toughness, thiab zoo txias thiab kub sib sau thiab vuam kev ua tau zoo. qhov ntsuas kub qis, cov khoom siv nyiaj txiag, thiab cov phab ntsa dej txias; Piv txwv li, cov kav dej me me yog siv los ua cov kav dej cua sov nrog cov phab ntsa kub ntawm ≤ 500 ℃, nrog rau cov kav dej txias ntawm phab ntsa thiab cov kav dej economizer. Vim lub graphitization tshwm sim los ntawm kev ua haujlwm ntev ntawm cov pa roj carbon steel siab tshaj 450 ℃, nws yog qhov zoo tshaj plaws los txwv qhov kev ua haujlwm ntev tshaj plaws ntawm cov kav dej raws li cov cua kub hauv qab 450 ℃. Cov hlau no tuaj yeem ua tau raws li cov kev xav tau ntawm superheaters thiab cov kav dej hauv qhov ntsuas kub ntawm lub zog, thiab muaj kev tiv thaiv oxidation zoo, zoo plasticity, toughness, vuam kev ua tau zoo thiab lwm yam kev ua haujlwm txias thiab kub, ua rau nws siv dav.

SA-210C (25MnG) yog qib steel hauv ASME SA-210 tus qauv. Nws yog ib txoj kab me me carbon manganese steel yeeb nkab siv hauv boilers thiab superheaters, thiab pearlescent hom high-strength steel. Cov txheej txheem ntau lawm ntawm cov hlau no yog qhov yooj yim, thiab nws cov kev ua haujlwm txias thiab kub yog qhov zoo. Hloov 20G nrog nws tuaj yeem txo qhov tuab ntawm cov phab ntsa nyias, txo cov khoom siv, thiab tseem txhim kho cov cua sov hloov ntawm boilers.

Nws qhov chaw siv thiab qhov kub thiab txias yog qhov zoo ib yam li 20G, feem ntau yog siv rau cov phab ntsa dej txias, cov khoom lag luam, cov cua kub tsis tshua muaj hluav taws xob thiab lwm yam khoom siv nrog kev ua haujlwm kub hauv qab 500 ℃.

Shandong Kungang Hlau Technology Co., Ltd. mas tsim steel yeeb nkab khoom. 20G thiab SA-210C feem ntau siv seamless cov ntaub ntawv nyob rau hauv warehouses, thiab tshwj xeeb specifications yuav ua tau raws li cov neeg muas zaub. Cov khoom yog ua los ntawm cov hlau zoo, thiab tag nrho cov ntsuas lub cev thiab tshuaj ua tau raws li lub teb chaws tus qauv. Cov khoom yog nrov nyob rau hauv domestic thiab txawv teb chaws. Peb tos ntsoov rau koj qhov kev sib tham!
