25MnG High Pressure Boiler Steel Yeeb Nkab
25MnG high-pressure boiler steel yeeb nkabyog seamless steel yeeb nkab siv rau cua sov nto yeeb nkab ntawm high-pressure boilers. Nws tus qauv siv yog GB/T5310-2017. Cov yeeb nkab steel no tsuas yog siv los tsim cov cua kub ntawm cov kav dej kub siab nrog kev ua haujlwm siab tshaj 9.8Mpa thiab ua haujlwm kub ntawm 450 degree thiab 650 degree, xws li headers, superheaters, reheaters, economizers, dej phab ntsa, thiab lwm yam. Tsis tas li ntawd, nws tseem tuaj yeem siv rau cov kav dej hauv kev lag luam petrochemical, thiab lwm yam.
Txij li thaum 25MnG boiler steel kav ua haujlwm nyob rau hauv qhov kub thiab txias, nws yog ib qho tsim nyog los xyuas kom meej tias cov kav hlau steel muaj lub zog ruaj khov, siab oxidation tsis kam, thiab kev ruaj ntseg zoo thaum lub sijhawm tsim khoom. Cov kav hlau hlau feem ntau yog xa mus rau hauv lub xeev kho cua sov, thiab muaj qee qhov yuav tsum tau ua rau microstructure, grain loj, decarburization txheej, thiab lwm yam ntawm cov yeeb nkab steel tiav.
Cov khoom siv thiab kev siv kub ntawm 25MnG Seamless boiler yeeb nkab yog qhov pib zoo ib yam li cov 20G. Nws yog tsuas yog siv rau cov phab ntsa dej-txias, economizers, low-temperature superheaters thiab lwm yam khoom uas muaj kev khiav hauj lwm kub hauv qab 500 degree. Yog li ntawd, nws muaj ntau daim ntawv thov kev cia siab hauv kev tsim cov boilers thiab superheaters.
