Kev piav qhia
Stainless hlau 317L yog qib molybdenum uas muaj cov pa roj carbon tsawg, nrog rau kev ntxiv ntawm chromium, npib tsib xee, thiab molybdenum. Qhov no muaj kev tiv thaiv corrosion zoo dua thiab muaj zog tiv thaiv cov tshuaj tua kab mob los ntawm acetic, tartaric, formic, citric, thiab sulfuric acids. 317L raj / kav dej muab kev nkag siab dua, thiab ua rau muaj kev hnov mob thaum welded, vim muaj cov ntsiab lus carbon tsawg. Ntxiv cov txiaj ntsig muaj xws li kev ntxhov siab rau kev tawg tsis kam, thiab lub zog tensile ntawm qhov kub siab. Qib 317l steel kav yog tsis sib nqus nyob rau hauv cov mob annealed. Txawm li cas los xij, tom qab vuam me ntsis hlau nplaum yuav raug pom.
317L STAINLESS STEEL PIPE PROPERTIES
317L stainless hlau raj xa los ntawm Arch City Steel & Alloy muaj cov khoom nram qab no:
Corrosion Resistance:
- Exhibits tshwj xeeb corrosion kuj nyob rau hauv ntau qhov chaw, tshwj xeeb tshaj yog nyob rau hauv acidic chloride ib puag ncig thiab ntau yam tshuaj.
- Zoo heev corrosion kuj nyob rau hauv daim ntawv thov qhov twg yam tsawg kawg nkaus paug yuav tsum tau
- 317L stainless hlau raj / yeeb nkab uas muaj cov ntsiab lus carbon tsawg muaj kev ua haujlwm zoo rau intergranular corrosion
- Lub siab nyiam ntawm cov hlau rau hauv qhov av thaum sib cuag nrog chlorides, bromides, phosphorus acids, thiab iodides yog suppressed.
Thaum tshav kub kub Resistance:
- Zoo heev tiv thaiv oxidation vim chromium-nickel-molybdenum cov ntsiab lus.
- Tso tawm qhov ntsuas qis ntawm qhov ntsuas kub txog 1600-1650 ° F (871-899 ° C), hauv cov huab cua zoo tib yam.
Welding yam ntxwv:
- Tsuas yog oxyacetylene welding, ntse welded los ntawm tag nrho cov fusion thiab kuj txoj kev.
- Filler hlau nrog npib tsib xee-puag thiab txaus chromium thiab molybdenum cov ntsiab lus yuav tsum tau siv los vuam hom 317L steel. Qhov no pab txhim kho corrosion kuj ntawm welded khoom. AWS E317L/ER317L los yog austenitic, tsawg carbon muab tub lim hlau uas muaj molybdenum cov ntsiab lus siab dua qib 317L kuj siv tau.
Machineability:
- Ua haujlwm ntawm qhov nrawm nrawm nrog cov khoom noj tas li yuav pab txo qis qhov nyiam ntawm qib 317L cov kav dej kom tawv.
- Qib 317L stainless hlau kav yog tawv dua 304 stainless thiab raug rau ntev thiab stringy nti thaum machined. Yog li ntawd, kev siv cov chip breakers yog pom zoo.
Daim ntawv thov:
Qib 317L stainless hlau raj feem ntau yog siv los tuav dej cawv, kua qaub dyestuffs, bleaching solutions, acetylating thiab nitrating mixtures, thiab lwm yam.
- Chemical thiab petrochemical ua khoom siv
- Cov ntaub ntawv thiab pulp tuav cov khoom siv
- Cov khoom siv ua zaub mov
- Condensers nyob rau hauv nuclear thiab fossil powered chaw nres tsheb
- Cov khoom siv textile
