AISI 316L Stainless Hlau Gearbox Vaj Tsev los ntawm Kev Lag Luam Casting

Khoom Taw Qhia thiab Qhov Zoo

Raws li crystallization ntawm niaj hnub kev lag luam precision manufacturing technology, AISI 316Lstainless hlau peev castinggearbox vaj tse tsis tsuas yog qhia qhov tshwj xeeb ntxim nyiam ntawm AISI 316L stainless hlau, tab sis kuj ua tiav high-precision replication ntawm complex qauv los ntawm cov txheej txheem qub thiab zoo ntawmpeev casting. AISI 316L stainless hlau, raws li ib tug tswv cuab ntawm lubaustenitic stainless hlauseries, sawv tawm ntawm ntau cov ntaub ntawv stainless hlau rau nws zoo heev corrosion kuj, kub tsis kam thiab zoo mechanical zog. Tshwj xeeb tshaj yog tom qab qhov sib ntxiv ntawm molybdenum, nws lub peev xwm los tiv thaiv pitting, crevice corrosion thiab kev nyuaj siab corrosion cracking yog ho txhim khu kev qha, ua cov khoom no nyiam cov khoom nyob rau hauv ntau yam xws li tshuaj lom neeg kev lag luam, khoom noj khoom haus, thiab marine engineering.

Tshuaj muaj pes tsawg leeg thiab microstructure

Cov tshuaj muaj pes tsawg leeg ntawm AISI 316L stainless hlau yog zoo tswj kom ntseeg tau tias nws zoo heev lub cev thiab tshuaj. Cov ntsiab lus carbon tsawg (≤0.03%) zoo zam qhov teeb meem ntawm intergranular corrosion thaum lub sij hawm vuam thiab txhim kho tag nrho corrosion kuj ntawm cov khoom. Cov ntsiab lus siab ntawm chromium (16.5% -18.5%) thiab npib tsib xee (12% -15%) muab cov khoom zoo heev oxidation tsis kam thiab toughness, thaum 2% -3% molybdenum cov ntsiab lus tseem ceeb txhim kho nws cov corrosion kuj nyob rau hauv ib puag ncig chloride. Tsis tas li ntawd, qhov tsim nyog ntawm nitrogen (≤0.10%) ntxiv txhim khu lub zog thiab hardness ntawm cov khoom yam tsis tau txi nws lub toughness. Qhov no optimized tshuaj muaj pes tsawg leeg ua ke, ua ke nrog cov nplua thiab niaj hnub microstructure tsim thaum lub sij hawm lub peev casting txheej txheem, enables 316L gearbox vaj tse kom muaj kev ruaj ntseg zoo thiab durability nyob rau hauv complex kev nyuaj siab.

Mechanical zog thiab kev ua tau zoo

AISI 316L stainless hlau gearbox vaj tse kuj ua tau zoo nyob rau hauv cov nqe lus ntawm txhua yam khoom. Nws lub zog tensile feem ntau yog nyob nruab nrab ntawm 485-620 MPa, thiab nws lub zog tawm los yog nyob rau hauv thaj tsam ntawm 170-300 MPa, uas txhais tau hais tias txawm tias nyob rau hauv cov xwm txheej hnyav, lub vaj tse tuaj yeem tuav cov qauv kev ncaj ncees thiab tsis ua rau cov yas deformation lossis tawg. Nyob rau tib lub sijhawm, qhov elongation txog li 40% thiab qhov cuam tshuam zoo toughness ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub tsev thaum raug cuam tshuam los ntawm kev thauj khoom. Tsis tas li ntawd, AISI 316L stainless hlau kuj tseem muaj qhov kub thiab txias zoo heev thiab tuaj yeem tswj cov khoom siv kho tshuab ruaj khov nyob rau hauv qhov chaw txias heev, uas yog qhov tseem ceeb tshwj xeeb rau cov khoom siv uas yuav tsum tau ua haujlwm nyob rau hauv cov polar lossis dej hiav txwv tob.
