13CrMo4-5 ND Alloy Steel Seamless Yeeb Nkab
09CrCuSb (ND) seamless steel raj rau sulfuric acid kuj, tsis tshua muaj dej dew point thiab corrosion
ND steel yog ib hom tshiab ntawm cov hlau tsis tshua muaj hlau, piv nrog rau lwm cov hlau, xws li cov hlau tsis tshua muaj carbon steel, Corten, CRIA, ND steel muaj qhov zoo ntawm corrosion kuj zoo heev thiab txhua yam khoom.Cov txiaj ntsig kev sim tau pom tias qhov kev tiv thaiv corrosion ntawm ND steel hauv aqueous daws zoo li sulfuric acid, hydrochloric acid thiab sodium chloride yog siab dua carbon steel.Qhov tseem ceeb tshaj plaws yog lub peev xwm ntawm sulfuric acid dew pointcorrosion kuj;Cov cuab yeej cuab tam yog siab dua thiab ruaj khov dua cov pa roj carbon steel los ntawm chav tsev kub txog 500 C, thiab qhov kev ua haujlwm vuam yog zoo.ND steel ib txwm siv rau kev tsim khoom lag luam, cov khoom siv hluav taws xob, cov cua sov ua ntej, txij li xyoo 1990, ND steel tau siv dav hauv kev lag luam ntawm kev lag luam thiab hluav taws xob.

T11 T12 T22 T91 T92 Alloy Steel Seamless Yeeb Nkab
Khoom nthuav qhia:
Alloy seamless steel yeeb nkab yog ib hom seamless steel yeeb nkab, nws qhov kev ua tau zoo dua li cov yeeb nkab seamless steel, vim tias cov yeeb nkab steel zoo li no muaj Cr piv.
Ntau, nws qhov kub thiab txias tsis kam, tsis kub tsis kam, kev ua haujlwm corrosion tsis zoo piv rau lwm yam seamless steel yeeb nkab, yog li cov yeeb nkab alloy hauv cov roj, tshuaj lom neeg kev lag luam, hluav taws xob, boiler thiab lwm yam lag luam tau dav siv.
Alloy seamless steel yeeb nkab muaj cov khoom xws li silicon, manganese, chromium, npib tsib xee, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, txhuas, tooj liab, boron, tsis tshua muaj ntiaj teb thiab lwm yam.

A106B A210A1 A210C / Carbon Steel Seamless yeeb nkab
Khoom nthuav qhia:
Boiler yeeb nkab yog ib hom seamless yeeb nkab.Txoj kev tsim khoom yog tib yam li cov yeeb nkab seamless, tab sis muaj cov kev cai nruj rau cov hom hlau siv los tsim cov yeeb nkab steel.
Cov khoom siv hluav taws xob ntawm cov yeeb nkab boiler yog qhov ntsuas tseem ceeb los xyuas kom meej qhov kev pabcuam zaum kawg (cov khoom siv tshuab) ntawm cov hlau, uas nyob ntawm cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov ntawm cov hlau.Nyob rau hauv cov txheej txheem steel yeeb nkab, raws li kev siv sib txawv, qhov kev ua tau zoo tensile (lub zog tensile, yield zog los yog yield point, elongation), nrog rau hardness thiab toughness indicators, as well as high and low temperature kev ua tau zoo los ntawm cov neeg siv.
Nyob rau hauv cov txheej txheem ntawm seamless steel yeeb nkab rau boiler, kev kho cua sov yog cov txheej txheem tseem ceeb.Kev kho cua sov muaj qhov cuam tshuam tseem ceeb rau qhov zoo ntawm sab hauv thiab qhov chaw zoo ntawm seamless steel yeeb nkab, uas yog qhov tseem ceeb tshwj xeeb rau kev tsim cov hlau alloy seamless steel yeeb nkab.
Peb lub tuam txhab txais kev kho cua sov uas tsis yog oxidation, kev tsim cov kav hlau steel nrog lub koom haum metallographic ruaj khov thiab zoo sab hauv thiab sab nrauv zoo, siv eddy tam sim no thiab ultrasonic tsis siv neeg qhov tsis pom kev, cov yeeb nkab steel ib los ntawm ib qho rau eddy tam sim no qhov teeb meem nrhiav pom thiab ultrasonic flaw detection.Nrog ultrasonic thickness ntsuas thiab oblique qhov tsis pom kev ua haujlwm, nws tuaj yeem kuaj xyuas cov txheej txheem tsis xws luag hauv cov yeeb nkab steel.
