Tsis tas li ntawd, qhov kawg lub zog ntawm 1.4401 qib stainless hlau yog ntau dua li ntawm 304 qib stainless hlau. Peb lub tuam txhab 1.4401 zoo stainless hlau cov khoom muaj nyob rau hauv rods, hexagons, lamashapes thiab squares nyob rau hauv ntau yam thicknesses, cov ntaub ntawv npe yog raws li nram no. Qib 316 stainless hlau tseem hu ua 1.4401 qib stainless hlau.

Siv thaj chaw:

1.4401 zoo stainless hlau khoom, dav siv vim nws zoo. Piv txwv li, stainless hlau yog pom zoo rau siv nyob rau hauv tso tsheb hlau luam thiab cia tso tsheb hlau luam rau corrosive kua nyob rau hauv chav kawm ntawv 316 (1.4401), tshuaj thiab petrochemical kev lag luam, chav boilers, cov xim kev lag luam, zaub mov factories thiab mining.

Txheej txheem cej luam ntawm cov yam ntxwv zoo:

1.4401 stainless hlau Raws li EN tus qauv 1.4401 zoo stainless hlau.

Stainless hlau qib 1.4401 tseem hu ua X5CrNiMo17-12-2 raws li EN cov qauv.

1.4401 thiab 316L stainless hlau zoo stainless hlau 304 zoo stainless hlau muaj cov qib siv dav tshaj plaws ntawm stainless hlau.

Qhov zoo no yog qib stainless hlau.

Cov qib stainless hlau no ua tau zoo thiab weld zoo.

Stainless hlau ntawm qhov zoo no yuav tsis nyiam cov hlau nplaum thiab tiv taus corrosion heev.

1. Cov corrosion kuj ntawm 4401 qib stainless hlau yog zoo dua li ntawm 304 qib stainless hlau.

Kev tsim cov txheej txheem txhaj tshuaj molding

Kev txhaj tshuaj molding yog thawj zaug siv hauv yas molding. Thaum ntxov li xyoo 1862, Alexander Parkes hauv tebchaws Askiv tau thov kev txhaj tshuaj molding los tsim cov combs, kaus mom thiab lwm yam khoom. Cov khoom tseem ceeb ntawm Baishi yas yog nitrocellulose (NC) ntxiv rau ib qho me me ntawm lwm cov tshuaj, ua rau nws cov yas thiab qee yam ntawm lub cev. Xyoo 1869, lub tshuab luam ntawv Askiv, Hytt, tau txhim kho Persian yas thiab ua celluloid, tab sis tseem yog nitrocellulose. Xyoo 1878, nws tau txhaj tshuaj celluloid rau hauv ntau kab noj hniav los npaj cov khoom. Cov pwm no twb muaj lub ntsiab khiav, khiav thiab khawb. Xyoo 1879, Grey tau tsim lub ntiaj teb thawj cov ntsia hlau extruder hauv tebchaws Askiv, thiab ib puag ncig tib lub sijhawm, ntau lwm tus kuj tau tsim ntau yam qauv. Vim tias celluloid yog cov nplaim taws heev, nws tsis haum rau kev txhaj tshuaj molding. Kev txhaj tshuaj molding thev naus laus zis tau tsim kho ntxiv mus txog xyoo 1919 thaum Eichengrumn tau qhia txog cellulose acid (CA) raws li kev txhaj tshuaj molding raw khoom. Xyoo 1920, kev txhaj tshuaj molding tau dhau los ua cov txheej txheem kev lag luam, uas tuaj yeem ua cov thermoplastic polymers rau hauv cov khoom nrog cov duab nyuaj. Lub feeder yog lub plawv ntawm lub tshuab txhaj tshuaj molding. Nyob rau hauv 1932, Hans Gastrovl ntawm lub teb chaws Yelemees tsim lub feeder nrog ib tug shunt shuttle, uas ua rau kom lub cua sov cheeb tsam ntawm lub polymer thiab kov yeej qhov tsis zoo ntawm thermal conductivity tsis zoo thiab tsis sib xws ntawm plastics. Ib feem ntawm qhov ntim ntawm cov khoom raug txo, thiab qhov kev tiv thaiv yog nce, uas ua rau nws nyuaj rau cov yaj mus txhaj rau hauv kab noj hniav. Xyoo 1930, American Celluloid Company tau tsim cov ntsia hlau yaj txhaj tshuaj molding. Xyoo 1940, lub tuam txhab German BASF tau tsim cov ntsia hlau ncaj qha txhaj molding txoj kev. Xyoo 1970s yog lub sijhawm tseem ceeb ntawm kev hloov pauv hauv kev txhim kho tag nrho cov kev lag luam yas, uas ua rau muaj kev loj hlob zoo ntawm kev txhaj tshuaj molding.
