Qhov sib txawv ntawm 304 thiab 316 STAINLESS STEEL
Thaum xaiv ibstainless hlauuas yuav tsum tau tiv thaiv corrosive ib puag ncig,austenitic stainless hlaufeem ntau yog siv. Muaj cov khoom siv kho tshuab zoo heev, cov nyiaj npib tsib xee thiab chromium hauv austenitic stainless hlau kuj tseem ua rau muaj kev tiv thaiv corrosion zoo heev. Tsis tas li ntawd, ntau austenitic stainless hlau yog weldable thiab formable. Ob ntawm cov qib siv ntau dua ntawm austenitic stainless hlau yog qib304thiab316. Txhawm rau pab koj txiav txim siab qib twg yog rau koj qhov project, qhov blog no yuav tshuaj xyuas qhov sib txawv ntawm 304 thiab 316 stainless hlau.
304 Stainless hlau
Qib 304 stainless hlau feem ntau suav hais tias yog cov hlau tsis zoo tshaj plaws austenitic. Nws muaj cov ntsiab lus npib tsib xee siab uas feem ntau yog nruab nrab ntawm 8 thiab 10.5 feem pua ntawm qhov hnyav thiab qhov ntau ntawm chromium ntawm kwv yees li 18 mus rau 20 feem pua ntawm qhov hnyav. Lwm cov ntsiab lus tseem ceeb xws li manganese, silicon, thiab carbon. Cov seem ntawm cov tshuaj muaj pes tsawg leeg yog cov hlau.
Qhov siab ntawm chromium thiab npib tsib xee muab 304 stainless hlau zoo heev corrosion kuj. Kev siv ntau yam ntawm 304 stainless hlau suav nrog:
- Cov khoom siv xws li tub yees thiab tshuab ntxhua khaub ncaws
- Khoom noj khoom haus ua lag luam
- Fasteners
- Piping
- Kub exchangers
- Cov qauv hauv ib puag ncig uas yuav corrode tus qauv carbon steel.
316 Stainless hlau
Zoo ib yam li 304, Qib 316 stainless hlau muaj ntau cov chromium thiab npib tsib xee. 316 kuj muaj silicon, manganese, thiab carbon, nrog rau feem ntau ntawm cov muaj pes tsawg leeg yog hlau. Qhov sib txawv loj ntawm 304 thiab 316 stainless hlau yog cov tshuaj lom neeg muaj pes tsawg leeg, nrog 316 muaj qhov tseem ceeb ntawm molybdenum; Feem ntau 2 mus rau 3 feem pua ntawm qhov hnyav vs tsuas yog cov lej pom nyob rau hauv 304. Cov ntsiab lus molybdenum siab dua ua rau qib 316 muaj zog tiv thaiv corrosion.
316 stainless hlau feem ntau suav hais tias yog ib qho kev xaiv zoo tshaj plaws thaum xaiv ib qho austenitic stainless hlau rau kev siv dej hiav txwv. Lwm yam kev siv ntawm 316 stainless hlau suav nrog:
- Cov khoom siv tshuaj ua haujlwm thiab khaws cia.
- Cov cuab yeej siv hluav taws xob
- Cov khoom siv kho mob
- Marine ib puag ncig, tshwj xeeb tshaj yog cov uas muaj chlorides tam sim no
Yam Koj Yuav Tsum Siv: Qib 304 lossis Qib 316?
Nov yog qee qhov xwm txheej uas 304 stainless hlau yuav yog qhov kev xaiv zoo dua:
- Daim ntawv thov yuav tsum tau zoo heev formability. Cov ntsiab lus molybdenum siab dua hauv Qib 316 tuaj yeem muaj kev cuam tshuam tsis zoo rau kev tsim.
- Daim ntawv thov muaj kev txhawj xeeb txog tus nqi. Qib 304 feem ntau pheej yig dua qib 316.
Nov yog qee qhov xwm txheej uas 316 stainless hlau yuav yog qhov kev xaiv zoo dua:
- Ib puag ncig suav nrog ntau cov ntsiab lus corrosive.
- Cov khoom yuav muab tso rau hauv qab dej los yog raug dej tsis tu ncua.
- Hauv cov ntawv thov uas xav tau ntau zog thiab hardness.
