Stainless hlau khoom

Q1: Lub luag haujlwm ntawm molybdenum hauv 316 stainless hlau yog dab tsi?

A1: Molybdenum tuaj yeem txhim kho lub peev xwm passivation ntawm stainless hlau, ua rau cov yeeb yaj kiab oxide nto ruaj khov thiab ntom. Nws tuaj yeem tiv thaiv corrosion ntawm chloride ions, uas yog vim li cas 316 stainless hlau muaj corrosion kuj zoo heev nyob rau hauv dej ntsev thiab acidic ib puag ncig.

Q2: Dab tsi yog daim ntawv thov kev lag luam ntawm 316 stainless hlau?

A2: Nws yog dav siv hauv cov khoom siv hauv hiav txwv (xws li cov nkoj hull qhov chaw, cov kav dej hiav txwv), cov khoom siv tshuaj (reactors, tank tank), kev ua zaub mov (tshwj xeeb tshaj yog siab - zaub mov ntsev), cov khoom siv kho mob, thiab kev kho kom zoo nkauj ntawm ntug dej hiav txwv.

Q3: Dab tsi yog qhov corrosion kuj ntawm 316 stainless hlau piv rau 304?

A3: 316 stainless hlau muaj qhov zoo corrosion kuj zoo dua li 304, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride ions. Piv txwv li, hauv dej hiav txwv, 304 tuaj yeem corrode tom qab siv sijhawm ntev -, thaum 316 tuaj yeem tswj tau qhov ua tau zoo. Nws kuj muaj qhov ua tau zoo dua rau sulfuric acid, phosphoric acid, thiab lwm yam acids.

Q4: Dab tsi yog cov cuab yeej cuab tam ntawm 316 stainless hlau?

A4: Lub zog tensile ntawm 316 stainless hlau yog 515-720 MPa, lub zog tawm los yog ≥205 MPa, thiab elongation yog ≥40%. Nws muaj qhov zoo toughness thiab ductility, tuaj yeem ua tiav los ntawm stamping, dabtsi yog khoov, vuam, thiab lwm yam txheej txheem, thiab tsim nyog rau kev tsim cov khoom lag luam.

Q5: Puas yog 316 stainless hlau haum rau siab -kev siv kub?

A5: Yog lawm, 316 stainless hlau tuaj yeem siv tsis tu ncua ntawm qhov kub txog li 870 ° C, uas zoo ib yam li 304. Tab sis nyob rau hauv siab - kub thiab siab - ib puag ncig corrosion, 316 qhov kev ua tau zoo dua qub. Txawm li cas los xij, nws yuav tsum zam kom tsis txhob siv nws hauv qhov chaw txo qis tshaj 600 ° C rau lub sijhawm ntev.
