ASME SA 790 UNS S32750 Pipe Txheej txheem cej luam
Alloy 2507 (UNS S32750)yog ib qho super duplex stainless hlau nrog siab chromium, molybdenum, thiab nitrogen cov ntsiab lus uas muab kev tiv thaiv zoo heev rau pitting, crevice, thiab dav corrosion.ASME SA 790 UNS S32750kuj muaj kev tiv thaiv zoo heev rau chloride kev nyuaj siab corrosion cracking, siab thermal conductivity, thiab qis coefficient ntawm thermal expansion. Lub teeb yuag S32750 cov khoom siv feem ntau tuaj yeem siv los ua kom tiav tib lub zog tsim raws li cov hlau nplaum tuab tuab. Cov txiaj ntsig kev txuag tau qhov hnyav tuaj yeem txo tus nqi tag nrho ntawm kev tsim khoom.
ASTM A790 / A790M -22 Txuj
Standard Specification rau Seamless thiab Welded Ferritic / Austenitic Stainless hlau yeeb nkab
ASTM A790 / ASME SA 790 specification npog seamless thiab ncaj-seam welded ferritic / austenitic steel yeeb nkab rau corrosive kev pab cuam nrog tshwj xeeb tseem ceeb ntawm kev tiv thaiv kev nyuaj siab corrosion cracking.Super duplex 2507 yeeb nkabyuav tsum tau tsim los ntawm seamless los yog tsis siv neeg vuam txheej txheem uas tsis muaj muab tub lim hlau ntxiv nyob rau hauv vuam ua hauj lwm. Peb tus neeg muag khoom yuav ua qhov kev sim tensile, hardening test, flattening test, hydrostatic test thiab non-destructive hluav taws xob kuaj ntawm txhua batch ntawm kav.
ASME SA 790 UNS S32750 Cov txheej txheem tsim khoom
Kub txoj kev
UNS S32750 super duplex yuav tsum kub ua hauj lwm ntawm 1875 degree F thiab 2250 degree F. Kev daws annealing yuav tsum tau ua nyob rau ntawm qhov tsawg kawg nkaus kub ntawm 1925 degree F ua raws li los ntawm cua ceev ceev los yog dej quench.
Txias txoj kev
A790 S32750 yog qhov nyuaj rau kev sib sib zog nqus nqus, ncab txoj kev sib sau thiab cov txheej txheem zoo sib xws dua li austenitic stainless hlau. Thaum tsim kom muaj ntau tshaj 10% txias deformation, tshuaj annealing thiab quenching yog pom zoo.
Kev kho cua sov
Kev daws annealing yuav tsum tau ua nyob rau ntawm qhov kub ntawm qhov tsawg kawg nkaus ntawm 1925 degree F. Annealing yuav tsum tam sim ntawd ua raws li huab cua ceev los yog dej quench.
Vuam
ASTM S32750 muaj qhov zoo weldability thiab tuaj yeem koom nrog nws tus kheej lossis lwm yam khoom siv los ntawm hlau arc vuam (SMAW), roj tungsten arc vuam (GTAW), plasma arc vuam (PAW), flux cored arc vuam (FCW), lossis submerged arc vuam ( SAW).
