Dab tsi yog qhov sib xws thiab sib txawv ntawm 16mn alloy hlau yeeb nkab thiab Q345B cov yeeb nkab steel?
Cov tshuaj lom neeg muaj kuab lom ntawm 16mn thiab Q345b yog zoo sib xws, puas yog qhov kev tswj hwm lub teb chaws tshiab, yog li muaj kev sib luag tshiab ({}}℃cuam tshuam lub zog loj dua los yog sib npaug 34J) {. hauv cov ntawv thov tswv yim zoo li cas los ntawm ob qho tib si vuam.
Yuav ua li cas kev ua tau zoo ntawm 16mn alloy Steel Yeeb Sib Xws Nrog 20 # Cov Yeeb Nkab Hlau?
20# steel pipe has a slightly higher carbon content (0.17%-0.24%), but lacks the strengthening effect of manganese, so its strength is lower than 16Mn (yield strength 245MPa vs 345MPa). 20# steel has better plasticity and weldability, and is suitable for cold processing (such as elbows and tees), while 16Mn is more suitable for pressure-bearing parts. In terms of cost, 20# steel pipe is 5%-10% cheaper, but the wall thickness needs to be increased under the same load. For low temperature environments (>{{0-20 degree), kev ua haujlwm ntawm ob yog zoo sib xws, tab sis 16mn yog zoo dua hauv qab {}℃.
Dab tsi yog qhov sib txawv ntawm daim ntawv thov cov xwm txheej ntawm 16mn alloy steel yeeb nkab thiab cov yeeb nkab steel hlau (304)?
304 stainless hlau muaj far superor corrosion tsis kam rau 16mn thiab yog qhov tsim nyog rau cov khoom siv huv si thiab cov tshuaj muaj zog rau lub zog kom huv (304. 16mn tsuas txwv rau hauv qab 450 degree.}}}}} {{15} {. Cov pipelines tuaj yeem siv 16mn stainless hlau lined pipes .
Kev sib piv ntawm cov kev ua tau kub siab ntawm 16mn alloy steel yeeb nkab thiab 15clo alloy steel yeeb nkab
15CrMo contains chromium (0.8%-1.2%) and molybdenum (0.4%-0.6%), and its high temperature strength (strength at 500℃>2 npaug ntawm 16mn) thiab oxidation tiv taus zoo dua 16mn, yog li ntawd nws yog qhov nyuaj { 30% {{{10% siab dua li ntawm 16mn, yog li nws tsuas yog siv nyob rau hauv qhov tseem ceeb thiab kev kub siab.
Dab tsi yog qhov zoo ntawm 16mn alloy steel yeeb nkab hauv cov nqe lus ntawm kev ua tau zoo?
Tus nqi-ua tau zoo ntawm 16mn alloy steel yeeb nkab yog 30% siab dua Q235, thaum tus nqi tsuas yog nce los ntawm 10%-15%; ② Qhov kev siv vuam yog paub tab thiab kev tsim kho yooj yim; Nws tuaj yeem hloov kho qee cov ntawv thov steel hlau thiab ua tau raws li cov cai tshuaj tiv thaiv corrosion los ntawm kev kho mob saum npoo; ④ Cov khoom lag luam muaj peev xwm txaus thiab kev xa khoom yog luv; Tus nqi rov ua dua tshiab yog qhov siab, thiab cov qauv ua haujlwm siab dua li cov roj ntsha tsis zoo, 16mn tseem yog qhov kev xaiv thiab kev xaiv tswv yim {}
