K500 yog dab tsi?
Nqe lus piav qhia:
Alloy K -500, feem ntau hu ua "K-Monel", yog ib qho nag lossis daus-tawv-tooj liab. Nws muaj corrosion tsis zoo ib yam li alloy 400 nrog ntxiv dag zog thiab hardness. Qhov sib ntxiv ntawm txhuas thiab titanium rau tus menyuam npib tsib xee-tooj liab tso cai rau kev kho cua sov tom ntej kom txhim kho cov khoom siv neeg kho cua. Alloy k {6}}}}}} Tseem muaj cov khoom sib nqus tsawg thiab muaj zog uas tsis muaj zog tshaj qhov kub thiab txias.
Kev Lag Luam thiab Kev Siv
Alloy K -500 Puas nquag siv hauv cov tub rog, tshuaj lom neeg, roj thiab cov ntaub ntawv, kev lag luam khoom noj, thiab kev lag luam hluav taws xob. End uses for Alloy K-500 include fasteners, springs, chains, pump and valve components, drill collars, scrapers, scrapers, agitator shafts, impellers, sensors, electrical components, and other highly corrosive applications where strength and hardness are important.
Corrosion Kuj:
Cov corrosion tsis kam ntawm k -500 alloy yog zoo li ntawm alloy-{}}}}}}} Alloy. Lub hydrogen sulfide ua rau k {4 4}}} alllo heev pab tau nyob rau hauv ib puag ncig ib puag ncig, ua rau nws zoo tagnrho rau cov ntawv thov kev ua haujlwm. Qhov qis dua corrosion hauv dej hiav txwv ua rau k -500} Alloy alloy qhov kev xaiv zoo rau kev lag luam marine. Pitting yuav tshwm sim rau cov neeg tsis huv lossis cov zaub mov tsis tshua muaj dej hiav txwv, tab sis cov pitting tus nqi yuav kawg thaum pib intrusually.
Fabrication thiab kev kho cua sov:
K {{{{{0}}}} alloy tuaj yeem siv tau siv cov qauv kev lag luam. Kub ua hauj lwm ntawm k -500}} Alloy allloy yuav tsum tau ua nyob rau ntawm 1600 degree yuav tsum coj mus ua kev saib xyuas kom tsis txhob ntev ntev. Tom qab kev ua haujlwm kub, cov khoom yuav tsum tau ua kom dej quenched los ntawm qhov kub tsis tsawg K -500 alloy yog qhov yooj yim tshaj plaws rau tshuab hauv anealed mob. Yog li ntawd, kev coj ua zoo tshaj plaws yog tshuab loj hlob, hnub nyoog tawv, thiab tom qab ntawd lub tshuab kom loj. Shrinkage yuav tshwm sim thaum laus, thiab 0.0002 nti / nti ntawm loj yuav tsum tau txiav txim siab ua ntej kev laus.
Vuam K -500} almoy yog qhov zoo tshaj plaws ua tiav los ntawm roj tungsten arc vuam (gtaw). Tus muab tub lim hlau Aws A5.14 eNMICU -7 yog feem ntau siv rau kev sib koom tes. Welds ua nrog cov tub muab ua tsav hlau no yuav tsis muaj lub zog ntawm niam txiv hlau vim tias nws tsis tuaj yeem yog hnub nyoog tawv. Rau Welds qhov twg lub zog yog xav tau, Aws 5.14 eNKIFecr {{6} Siv tub lim hlau.
Lub alloy yuav tsum tau daws anealed ua ntej kev laus kom yaj microstration micros tsim rau thaum dhau los ua. Yog tias cov khoom siv tau kub ua haujlwm, qhov kub siab yuav tsum tau 1800 degree F. Yog tias cov khoom txias yuav tsum tau txo qis kev loj hlob dhau kev loj hlob. Quenching hauv dej tam sim ntawd tom qab kev daws analing kev zam txhua yam naghaum ntawm cov hnub nyoog-hardening los ua ke. Cov khoom siab tshaj plaws yog tau los ntawm cov hnub nyoog Annealening (mos) F thiab 11 teev F thiab cov neeg txias kom txog thaum muaj 900 tus neeg txias.
