09MnNiDR Pressure Vesse Steel Description

GB 3531 09MnNiDR Pressure Vesse Steel yog Manganese-Nickel alloy steel, centigrade tsab ntawv D yog siv rau qhov kub thiab txias, tsab ntawv R yog rau boiler thiab lub nkoj siab siv.Qhov ntsuas kub tsawg yuav tsum tau ua rau 09MnNiDR centigrade, qhov cuam tshuam tus nqi zog yuav tsum siab dua 34 J.

09 qhia tias cov ntsiab lus ntawm C yog kwv yees li 0,09%, Mn qhia tias cov ntsiab lus ntawm Mn yog li 1%, thiab Ni qhia tias muaj cov kab ntawm cov ntsiab lus alloying, feem ntau siab dua 0, 30 yog cov ntsiab lus alloying. Nws yuav tsum tau qhia. D txhais tau tias "tsawg kub" yog thawj tsab ntawv ntawm pinyin. R stands rau "container" thiab yog thawj tsab ntawv ntawm pinyin.

09MnNiDR steel yog ferrite + ib qho me me ntawm pearlite qis kub hlau. Vim nws cov ntsiab lus carbon tsawg, nws belongs rau qis- alloy structural steels thiab Mn thiab Ni yog nws cov alloys tseem ceeb. Mn feem ntau txhim kho lub zog ntawm cov hlau los ntawm cov khoom siv ntxiv dag zog, thaum Ni tuaj yeem txhim kho qhov kub tsis tshua muaj zog ntawm ferrite thiab muaj cov txiaj ntsig ntawm kev txo qhov kub thiab txias ntawm kev hloov pauv.

09MnNiDR Pressure Vesse Steel yog lub phaj tshwj xeeb rau cov hlab ntsha siab nrog qib siab zog. Nws muaj cov khoom zoo txhua yam thiab kev ua haujlwm zoo. Cov ntsiab lus ntawm phosphorus thiab sulfur yog me ntsis qis dua li cov hlau zoo tib yam. Ntxiv rau qhov siab dua tensile lub zog thiab elongation yuav tsum tau tshaj li cov hlau zoo tib yam, nws tseem yuav tsum tau ua kom muaj kev cuam tshuam toughness. Nws yog tam sim no feem ntau siv steel phaj hauv siab hlab ntsha hauv kuv lub teb chaws.

Mn feem ntau txhim kho lub zog ntawm cov hlau los ntawm kev daws teeb meem ntxiv dag zog, thaum Ni tuaj yeem txhim kho qhov qis -kub 09MnNiDR toughness ntawm ferrite, thiab muaj cov txiaj ntsig ntawm kev txo qis kev hloov pauv txias txias. Nws cov pa roj carbon sib npaug yog tsawg dua los yog sib npaug rau 0, 44, muaj qhov sib npaug me me, thiab tsis yooj yim rau cov kab mob khaub thuas. Lub weld muaj zoo plasticity thiab toughness, thiab feem ntau tsis tas yuav preheating. Thaum lub thickness ntawm lub phaj tshaj ib tug tej thickness, lub rigidity ntawm lub sib koom tes yog loj los yog cov pa roj carbon sib npaug yog siab, preheating yuav tsum tau txiav txim siab. Txawm li cas los xij, qhov ntsuas kub ua ntej yuav tsum tsis txhob siab dhau, txwv tsis pub cov nplej hauv tshav kub- thaj tsam cuam tshuam yuav loj hlob thiab oxides yuav los nag rau ntawm cov ciam teb. Yog li ntawd, lub vuam cua sov input thiab interlayer kub yuav tsum tau tswj thaum lub sij hawm vuam, thiab kev ntxhov siab kev kho cua sov yuav tsum tau nqa tawm tom qab vuam.
