Lub "317L" nyob rau hauv 317l Sainless Steel Pipe Tubing yog hais txog ib qho ultra- qis carbon austenitic stainless hlau, cov tub ntxhais alloying cov ntsiab lus ntawm 18% Chromium (Cr), 12% Nickel (Ni), thiab 2.5% Molybdenum (Mo). Tsim raws li lub hauv paus ntawm 304/304L, qhov sib ntxiv ntawm molybdenum (Mo) ua rau nws muaj zog tiv thaiv corrosion los ntawm halides -tshwj xeeb yog cov tshuaj chloride ions (Cl⁻)- thiab tshwj xeeb yog txhim kho nws cov kev tiv thaiv rau pitting thiab crevice corrosion. Lub npe "L" txhais tau hais tias "tsawg carbon" (nrog cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.03%), yog li tiv thaiv kev cuam tshuam intergranular uas tuaj yeem tshwm sim tom qab vuam.
Lub siab salinity ntawm marine ib puag ncig ua rau muaj kev cuam tshuam loj heev rau cov khoom siv; Tsis tas li ntawd, dej hiav txwv yog nplua nuj nyob rau hauv chloride ions. 317L zoo tiv thaiv ob qho tib si dav dav thiab hauv cheeb tsam corrosion hauv dej hiav txwv, ua tau zoo tshaj 316L hauv qhov no thiab ua kom pom qhov zoo sib xws hauv qhov tob - hiav txwv lossis siab - nrawm seawater ib puag ncig.

Cov qhab nia xaiv tau
- Rau cov dej hiav txwv me me, TP316L yog qhov kev xaiv tsim nyog; nws yog 15-20% tsis tshua kim tshaj 317L, thaum muab piv rau vuam thiab ua cov yam ntxwv.
- Yog tias yuav tsum muaj qib sib npaug ntawm kev tiv thaiv corrosion, 2304 duplex stainless hlau yog ib qho kev xaiv; nws phim qhov corrosion kuj ntawm 317L thaum khav theeb muaj zog ntau dua -ntau dua ob npaug ntawm 317L.
- Txhawm rau hais txog qhov chaw nyob hauv dej hiav txwv huab cua -xws li cov uas tau ntsib nyob rau hauv qhov sib sib zog nqus - hiav txwv roj thiab roj platforms lossis hauv dej hiav txwv nrog cov tshuaj chloride ion ntau ntau-2507 super duplex stainless hlau yog pom zoo rau nws cov corrosion kuj zoo dua.
thaj chaw siv
317l Sainless Steel Yeeb Nkab Tubing feem ntau yog siv rau hauv thaj chaw xws li dej hiav txwv txias, desalination, thiab offshore platforms. Cov ntawv thov tshwj xeeb suav nrog:
- Hauv cov dej txias hauv dej hiav txwv, lawv feem ntau yog siv rau cov khoom siv hluav taws xob sib hloov, condensers, thiab cov kav dej txias uas raug rau cov dej hiav txwv tsis tu ncua.
- Ntawm ntug dej hiav txwv roj thiab roj platforms, lawv tau ua haujlwm rau cov kab hydraulic, cov cuab yeej siv, cov kab tshuaj txhaj tshuaj, thiab cov ntawv siv zoo sib xws.
- Hauv cov nroj tsuag desalination, lawv tau siv nyob rau hauv thim rov qab osmosis systems, evaporators, thiab brine kho pipelines.

FAQ
Q: Vim li cas thiaj xaiv 317L tsis yog 316L rau kev siv dej hiav txwv?
A: Vim tias 317L muaj cov ntsiab lus molybdenum ntau dua, thiab 317L stainless hlau muaj kev tiv thaiv zoo dua rau intergranular corrosion thiab kev ntxhov siab corrosion tawg dua li 316L stainless hlau.
Q: Puas yog cov yeeb nkab puas siv tshuaj annealing?
A: Tag nrho peb cov raj yog tsim los nrog kev daws teeb meem ntawm 1050 ~ 1150℃thiab txias txias, kom ntseeg tau zoo heev tiv thaiv intergranular corrosion, ua raws li qhov yuav tsum tau ua ntawm ASTM A213.
Q: Koj puas tuaj yeem txiav kuv qhov ntev?
A: Yog. Peb txhawb txiav rau txhua qhov ntev. Cov kav me me - txoj kab uas hla tuaj yeem txiav nrog qhov siab ntawm ± 0.050.1mm, ua rau lub ntsej muag tiaj tus, burr-dawb, thiab deformation-dawb.
