Stainless Hlau Phaj

Alloy 904L stainless hlau phaj nyob rau hauv thicknesses los ntawm 3 \ / 16 "los ntawm 2". Alloy 904L (tsis yog n08904) yog Superaustenitic Stainless hlau tsim rau corrosion thiab pitting yeem nyob rau hauv ntau cov txheej txheem ib puag ncig.

304 \ / 304L Stainless Hlau Phaj yog ib qho ntawm feem ntau ntau yam thiab dav siv cov qib tsis zoo. Vim nws cov ntsiab lus roj teeb qis dua thiab qib siab chromium muaj pes tsawg leeg, cov chav kawm qib no yog qhov zoo tshaj plaws hauv nws lub zog, corrosion tsis kam, thiab muaj peev xwm.

Thaum cov ntsiab lus chromium ntawm alloy yog qis dua tsawg kawg yog 12%, piv txwv li hauv Aerospace kev lag luam, lo lus "corrosion resistant steel" yog siv. Stainless tus hlau los hauv cov qib sib txawv thiab cov npoo ua tiav, nyob ntawm seb nws siv qhov twg.

Stainless hlau yog ib qho hlau alloy muaj tsawg kawg yog 10.5% chromium. Chromium ua cov txheej txheej nyias ntawm oxide nyob rau saum npoo ntawm cov hlau, hu ua "passivation txheej".

Stainless hlau kuj muaj ntau yam ntawm carbon, silicon thiab manganese. Lwm cov ntsiab lus, xws li npib tsib xee thiab molybdenum, tuaj yeem ntxiv rau impart lwm cov khoom muaj txiaj ntsig xws li kev ua kom haum thiab ua kom haum corrosion.

Qeb 304L tau siv dav hauv kev tsim kev lag luam thiab txhua hom qauv vuam tuaj yeem siv tau rau 304L phaj thiab 304l yeeb nkab. Tus "l" nyob rau hauv 304L sawv rau "cov ntsiab lus muaj peev xwm ntawm cov pa roj teeb" thiab qhia tau cov ntsiab lus ntawm cov roj carbon ntau kawg ntawm 0.035%. Tus "H" nyob rau hauv 304h sawv rau "cov ntsiab lus carbon siab", uas txhais tau tias cov ntsiab lus carbon tsis yog qis dua 0.04% thiab tsis ntau tshaj 0.10%.

SS 304, SS 304L, SS 316 thiab SS 316 thiab ss 316L stainless cov ntawv yog qhov nrov tshaj plaws thiab kev lag luam stainless hom studes. Stainless hlau 304 \ / 304l phaj thiab hlau tsis muaj roj av nrog rau cov chaw ua haujlwm zoo li cov tub rog ua haujlwm zoo li cov tub rog thiab kev lag luam.

304 Stainless Hlau Phaj muaj qhov kev tsim nyog zoo heev thiab tuaj yeem yooj yim welded los ntawm txhua txoj kev. 304 \ / 304L ob daim ntawv pov thawj.

304 Stainless Phaj yuav dhau los ua kev sib nqus me ntsis thaum ua haujlwm thiab tsis yog cua sov kho tau.
