Tag nrho cov qib stainless hlau 304, 304L, thiab 304H yog tshuaj sib xyaw nrog cov khoom xws li chromium, phosphorus, silicon, manganese, carbon, sulfur, molybdenum, thiab nickel. Dhau li ntawm lwm yam chromium, molybdenum, thiab npib tsib xee yog cov tseem ceeb hauv kev sib xyaw ua ke. Yog li, nws nthuav tawm cov txiaj ntsig zoo heev nrog rau lub zog tensile, zoo kub tsis kam, thiab elongation ntau yam. Feem ntau, tag nrho peb qib yog elongated mus txog qhov siab tshaj plaws ntawm 40%. Tsis tas li ntawd, lawv muaj qhov siab tshaj plaws melting point ntawm 1400 degrees Celsius (los yog 2550 degrees Fahrenheit) tshwj tsis yog rau 304H. Qib 304H muaj qhov sib txawv ntawm 2550 txog 2590 degrees Fahrenheit.
SS 304 / 304L / 304H Cov Ntawv & Phajyog siv heev los ntawm cov ntawv thiab cov ntaub so ntswg industries, textile khoom chaw tsim tshuaj paus, condensers nyob rau hauv fossil roj thiab nuclear roj tiam chaw nres tsheb, thiab petrochemical ua khoom manufacturers. Txoj kev xav tom qab cov lus qhia tshwj xeeb ntawm cov ntawv qib thiab daim hlau no yog tswj hwm los ntawm ASTM A240 thiab ASME SA240 tus qauv.
Lawv tau siv dav hauv kev tsim cov khoom siv hluav taws xob thiab cov txheej txheem tshuaj lom neeg cov hlab ntsha, cov tankers, lossis cia. Lawv nyiam siv rau cov khoom siv conveyor vim tias lawv muaj cov khoom yooj yim thiab tus nqi zoo. Qib 304 yog qhov xav tau heev hauv kev ua zaub mov thiab tuav kev lag luam vim tias lawv muaj kev tiv thaiv corrosion nrog rau qhov kub thiab txias adapters. Cov nplooj ntawv thiab daim hlau no tau siv ntau yam hauv kev lag luam architectural thiab kev tsim kho rau nws cov kev kub siab thiab kev ntxhov siab absorbance zoo.
SS 304 / 304L / 304H Cov Ntawv & Phajkuj mus los ntawm kev xeem sib txawv xws li PMI kev xeem, IGC xeem, tshuaj ntsuam xyuas, tshuaj ntsuam xyuas tshuab, flattening test, flaring test, macro/micro test, fumigation test, positive material analysis, etc.
