SUS304H Stainless Hlau: Tshuaj muaj pes tsawg leeg, muaj zog
Tso lus
SUS304H Stainless hlau yog dab tsi?
SUS304H yog qib austenitic stainless hlau, qhov tseem ceeb yog siab -carbon version ntawm tus qauv 304 stainless hlau. Qhov "H" qhia txog cov ntsiab lus ntawm cov pa roj carbon ntau dua (0.04-0.10% C), uas txhim kho lub zog, tshwj xeeb tshaj yog nkag mus thiab tawm lub zog ntawm qhov kub siab (txog li 1500℃F / 815℃). Nws yog qhov tsim nyog rau kev siv kub kub xws li boilers, kub exchangers, thiab petrochemical ua khoom siv.
H yog dab tsi hauv 304H?
Qhov "H" hauv 304H sawv cev rau "High" cov ntsiab lus carbon . 304H yuav tsum tsis pub tsawg dua 0.04 feem pua carbon, los yog ntau tshaj 0.10 feem pua. Cov pa roj carbon ntau dua ntawm 304H nce nws lub zog, yog li ASTM tensile thiab tawm lub zog ntawm 304H yog ntau dua 304L.

Cov tshuaj muaj pes tsawg leeg ntawm SS 304H yog dab tsi?
304H stainless hlau yog austenitic hlau nrog cov ntsiab lus tseem ceeb: 18-20% Chromium (Cr), 8-10.5% Nickel (Ni), thiab cov ntsiab lus carbon ntau dua ntawm 0.04-0.10% (piv rau 304/304L), uas boosts nws high-temperature zog thiab creep resistance.

Dab tsi yog cov khoom ntawm 304H cov khoom?
Alloy 304/304H muaj kev tiv thaiv corrosion zoo ib yam li 304/304L. Nws tiv taus atmospheric corrosion, nrog rau, me ntsis oxidizing thiab txo qhov chaw. Txawm li cas los xij, vim nws cov ntsiab lus carbon siab, Alloy 304/304H raug rau carbide nag lossis daus hauv tshav kub cuam tshuam ntawm welds.
Dab tsi yog qhov ntsuas kub ntawm 304H stainless hlau?
Dual certified 304/304H yog siv los ua cov khoom siv ntawm kev tsim kho mus txog 1500℃F. Kev ntsuas me ntsis pib ntawm 1200℃F. 304/304H ua tau raws li 0.04% cov ntsiab lus carbon tsawg thiab muaj cov nplej loj ntawm ASTM 7 lossis coarser.
Lub zog ntawm SUS304H stainless hlau yog dab tsi?
SUS304H stainless hlau muaj lub zog zoo, feem ntau nrog qhov tsawg kawg nkaus tensile lub zog ntawm Greater los yog sib npaug rau 515 MPa (75 ksi) thiab qhov tsawg kawg nkaus yield zog (0.2% offset) ntawm ntau dua los yog sib npaug rau 205 MPa (30 ksi), nrog rau ntau dua los yog sib npaug rau 40% elongation, 7} cov ntaub ntawv zoo xws li boiler tswj kev yooj thiab stability nyob rau hauv tshav kub.
Kev siv ntawm SUS 304H Stainless Hlau
304H stainless hlau feem ntau pom muaj nyob rau hauv cov roj refining, roj thiab tshuaj lom neeg kev lag luam thiab yog siv nyob rau hauv industrial boilers, siab hlab ntsha, tshav kub exchangers, pipelines thiab condensers. Cov khoom siv kuj tseem siv thoob plaws hauv kev lag luam tsim hluav taws xob.
Qhov txawv ntawm 304L thiab 304H Stainless hlau yog dab tsi?
Qhov sib txawv tseem ceeb ntawm 304 stainless hlau thiab 304H stainless hlau nyob hauv lawv cov ntsiab lus carbon . 304H yog siab - carbon version ntawm tus qauv 304 stainless hlau (nrog cov ntsiab lus carbon ntawm 0.04-0.10%), thaum tus qauv 304 muaj cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.08%. Yog li ntawd, 304H muaj superior kub-kub lub zog thiab creep kuj (xws li, siv nyob rau hauv lub tshav kub exchangers thiab boilers), thaum tus qauv 304 muab zoo corrosion kuj thiab formability, ua rau nws haum rau txhua txhua hnub khoom (xws li, cookware, dab dej).
