304 stainless hlau precision steel raj yog qhov tseem ceeb heev, tshwj xeeb tshaj yog nyob rau hauv kev lag luam hluav taws xob, qhov twg nws tuaj yeem pom nyob txhua qhov chaw. Cov hlau tsis muaj steel tuaj yeem tau txais kev tuav pov hwm hauv kev lag luam hluav taws xob nrog nws ob qho txiaj ntsig kev nyab xeeb, kev nyiam huv, thiab kev tiv thaiv corrosion. Nov yog qee cov ntawv thov sawv cev.

Ua ntej tshaj plaws, qhov chaw uas tuaj rau hauv kev sib cuag nrog cov khoom noj. 304 stainless hlau precision steel raj yog sib npaug rau "faucet" raws li lub qhov hluav taws xob dej. Kev sib cuag ncaj qha nrog cov dej haus yog qhov tshwj xeeb ntawm kev nyab xeeb thiab kev nyiam huv ntawm cov khoom siv. 304 stainless hlau tau lees paub los ntawm lub xeev ua zaub mov-qib stainless hlau. Cov nag lossis daus ntawm cov hlau hnyav xws li arsenic, cadmium, lead, chromium, thiab nickel ua tau raws li cov qauv nruj. Yog xav paub ntxiv, thov mus saib "GB 4806.9-2016 National Food Safety Standard".

Cov yeeb nkab fittings siv cov txheej txheem polishing kom tshem tawm qhov siab tshaj ntawm cov yeeb nkab sab hauv phab ntsa. Cov yeeb nkab phab ntsa tuaj yeem ua polished rau hauv daim iav nyhuv, uas txhim kho cov xeb tiv thaiv thiab scaling tsis kam ntawm cov yeeb nkab steel hlau thiab tshem tawm cov roj kom ua tiav qhov kev huv huv uas xav tau los ntawm qib zaub mov, yog li nws tuaj yeem siv nrog kev ntseeg siab. Lub ductility ntawm 304 stainless hlau precision steel raj yog δ5 (%) ≥ 40, hardness ≤ 201HBW, ≤ 92HRB, ≤ 210HV; Nws tsis yooj yim rau kev tawg thaum khoov, thiab tuaj yeem khoov rau hauv txhua lub kaum ntse ntse, nrog kev ua haujlwm zoo heev, txo tus nqi seem, thiab txuag cov nqi.

Tsis tas li ntawd, nws yog siv los ua ib lub raj xa hluav taws xob hauv cov cua kub cua sov, uas tau nyob rau hauv qhov kub thiab txias ib puag ncig ntev, thiab muaj cov kev cai nruj ntawm kev tiv thaiv corrosion thiab kub tsis kam. 304 stainless hlau tuaj yeem tiv taus qhov kub thiab txias ntawm 800 degrees Celsius, thiab nws cov thermal conductivity (W·m-1·K-1): (100 ℃) 16.3, (500 ℃) 21.5, yog qhov kev xaiv zoo tshaj plaws rau cov dej kub kub hloov pauv. cov raj. 304 stainless hlau precision steel hlab yog kho nrog ci daws annealing, uas heats lub steel raj ntawm qhov kub thiab txias nws sai sai, dissolves cov carbides nyob rau hauv lub koom haum, txhim kho corrosion kuj ntawm lub raj, thiab ncua lub neej kev pab cuam ntawm tshav kub. cev pauv. Precision polishing yog siv los txhim kho qhov smoothness ntawm cov phab ntsa hauv lub raj, ua rau lub raj phab ntsa tiv taus corrosion thiab scaling, thiab txhim kho kev ua haujlwm kub; stainless hlau yog ib qho yooj yim los txiav thiab tuaj yeem ua rau nyias-walled raj. Ntxiv nrog rau kev txhim kho kev hloov hluav taws xob, nws tseem tuaj yeem txuag nqi, thiab kev ua haujlwm thiab kev lag luam sib koom ua ke.

Cov saum toj no yog daim ntawv thov ntawm 304 stainless hlau raj hauv kev lag luam hluav taws xob raws li kev sib cuag ncaj qha nrog cov zaub mov thiab raws li cov cua kub pauv cov raj. Tom qab kev soj ntsuam ntxaws ntxaws ntawm cov khoom siv thiab kev ua tau zoo, nws tau kawm tias 304 stainless hlau precision steel raj tuaj yeem siv rau hauv txoj kev no.
