UNS S44700 Stainless Hlau Phaj

S44700 yog lub siab purity ferritic stainless hlau. Vim yog cov ntsiab lus ntawm chromium thiab molybdenum siab, thiab cov ntsiab lus carbon thiab nitrogen raug txo kom tsawg, qhov kev tiv thaiv corrosion ntawm UNS S44700 stainless hlau phaj yog txhim kho, tshwj xeeb tshaj yog cov kev nyuaj siab corrosion thiab pitting kuj, thiab nws muaj ib tug mos magnetic nyhuv. , tab sis qhov kub hloov pauv hloov qis dua thiab qhov toughness tau zoo dua. Qhov kev tiv thaiv corrosion yog sib npaug ntawm cov npib tsib xee ntshiab, thiab nws muaj qhov zoo toughness, ua formability thiab weldability.

Hlau (Fe): sib npaug.

Chromium (Cr): 25.0%-28.0%. Chromium yog qhov tseem ceeb rau kev tiv thaiv corrosion ntawm stainless hlau. Nws tuaj yeem tsim cov yeeb yaj kiab tiv thaiv chromium oxide ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom chromium oxide tiv thaiv zaj duab xis rau saum npoo kom tiv thaiv cov pa oxygen thiab lwm yam khoom siv corrosive los ntawm kev ntxiv corroding hlau.

Nickel (Ni): Cov ntsiab lus siab tshaj plaws yog 1.50%.

Molybdenum (Mo): Cov ntsiab lus yog 3.5-4.2%. Qhov sib ntxiv ntawm molybdenum tuaj yeem txhim kho corrosion kuj ntawm UNS S44700 stainless hlau daim hlau hauv qee qhov chaw tshwj xeeb, xws li hauv ib puag ncig uas muaj chloride ions.

Manganese (Mn): Cov ntsiab lus siab tshaj plaws yog 1.00%.

Silicon (Si): Cov ntsiab lus siab tshaj plaws yog 1.00%.

Phosphorus (P): Cov ntsiab lus siab tshaj plaws yog 0.040%.

Sulfur (S): Cov ntsiab lus siab tshaj plaws yog 0.030%.

Cov pa roj carbon (C): Cov ntsiab lus siab tshaj plaws yog 0.15%. Cov ntsiab lus qis dua yuav pab txhim kho qhov kev ua tau zoo ntawm kev sib txuas thiab kev sib txuas ntawm kev sib txhuam ntawm UNS S44700 stainless hlau daim hlau.

Tsis tas li ntawd, nws muaj cov lej ntawm lwm cov alloying ntsiab lus, xws li txhuas (Al) thiab titanium (Ti), uas pab ntxiv txhim kho cov khoom ntawm stainless hlau, xws li corrosion kuj thiab kub ua hauj.

Qhov ceev yog li 7.64g / cm³.

Tsis muaj cov ntaub ntawv meej meej ntawm qhov chaw melting.
