310s stainless hlau yog ib tug corrosion zoo-resistant ausustenitic stainless hlau alloy uas yog siv nyob rau hauv ntau qhov siab thiab corrosive ib puag ncig. Nws yog qhov kev xaiv zoo rau kev siv hauv petrochemical, tshuaj lom neeg, thiab kev ua kom sov, thiab lwm yam kev siv hluav taws xob kom kub. Ib tug 310s stainless hlau phaj yog lub tiaj tiaj, nyias daim ntawv ua los ntawm cov xaim tshwj xeeb no.
3.253ma (s30815) Phaj Stainless Hlau Phaj
Cov yam ntxwv: 253ma yog cua sov-resistant antustenitic stainless hlau tsim rau cov ntawv thov lub zog loj thiab zoo corrosion tsis kam. Nws cov kev ua haujlwm kub ntau yog 850-1100 ℃.
253Ma yog hom tshwj xeeb ntawm stainless hlau alloy uas yog tsim rau kev siv kub-kub. Nws muaj kev tiv thaiv zoo heev rau oxidation, sulfidation, thiab carburization ntawm ntug kub. Qhov no ua rau nws haum rau siv nyob rau hauv ntau yam kev lag luam, suav nrog cov uas cuam tshuam nrog cua sov thiab xeb, xws li cov petrochemical, thiab cov tshuab hluav taws xob, thiab cov tshuab hluav taws xob.253MA cov ntawv yog nyias, tiaj tus ntawm cov khoom ua los ntawm cov alloy no. Lawv siv nyob rau hauv ntau cov ntawv thov uas ua ke ntawm kev sib xyaw ua ke kub ua rau thiab corrosion tsis yog qhov tseem ceeb. Cov ntawv txheeb tau tuaj yeem txiav thiab tsim ua cov duab sib txawv kom tau raws li qhov xav tau ntawm ib qho haujlwm.
253mA cov ntawv, phiaj tshuaj tshuaj muaj pes tsawg
| Teem nqi | C | Cr | Mn | Si | P | S | N | Ce | Fe | Ni |
| 253ma | 0.05 - 0.10 | 20.0-22.0 | 0.80 max | 1.40-2.00 | 0.040 max | 0.030 max | 0.14-0.20 | 0.03-0.08 | Seem | 10.0-12.0 |
253A Cov Khoom Siv Phaj Cov Phaj
| Lub zog tensile | Tawm Zog (0.2% offset) | Elongation (hauv 2 hauv.) |
| PSI: 87,000 | PSI 45000 | 40% |
253ma phaj corrosion tsis kam thiab siv lub ntsiab kev siv:
1.Corrosion Kuj: 253MA tau ua tsis tau zoo, high-high-high-forrosion tsis kam, thiab zoo kawg li-kub tshuab zog muaj zog. Nws yog ua tau zoo nyob rau hauv kub ntau ntawm 850 txog 1100 ° C.
2.Temperatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatatature ntau, 253ma yog qhov zoo tshaj rau kev siv nyob rau hauv qhov kub thiab txias ntawm 850 txog 1100 ° C. Ntawm qhov kub ntawm 600 thiab 850 ° C, kev hloov pauv kev hloov pauv, ua rau txo qhov cuam tshuam nyuaj ntawm chav tsev.
3.Qhaechhanical lub zog: no alloy surpass dog dig stainless hlau, xws li 304 thiab 310s, hais txog lub zog luv tensile lub zog ntawm ntau qhov kub ntawm 20%.
4. DiCemical Composition: 253ma nta cov tshuaj lom neeg sib xyaw uas muaj kev sib xyaw ua ke nws qhov kev ua tau zoo hauv qhov kub ntawm 850-1100 ° C. Nws ua rau muaj kev ua haujlwm siab heev, nrog kev kub siab txog li 1150 ° C. Nws tseem muaj cov ntxig zoo dua thiab nkag mus rau hauv lub zog.
5.Corrosion Kuj: Ntxiv rau nws cov peev xwm siab kub, 253ma qhia tau zoo heev rau high-flower corrosion thiab txhuam corrosion thiab txhuam corrosion hauv feem ntau gaseous.
6.Qhov: Nws muaj lub zog muaj zog thiab lub zog tensile ntawm cov chaw kub.
7. Txheeb xyuas thiab Veldability: 253Ma yog paub txog nws cov kev muaj txiaj ntsig zoo, weldability, thiab machinility.
