ASTM A312 UNS S30815 Stainless Hlau Tube yog dab tsi?
ASTM A312 UNS S30815 (253MA®) stainless hlau raj yog lub siab -kub alloy paub txog nws cov oxidation zoo heev thiab creep tsis kam, ua rau nws yog ib qho zoo tagnrho lwm txoj rau ntau kim npib tsib xee-raws li alloys. Nws ua tiav cov khoom no los ntawm kev tswj xyuas qhov sib ntxiv ntawm silicon, nitrogen, thiab cerium, uas tsim cov txheej txheem oxide ruaj khov thiab txhim khu lub zog ntawm qhov kub txog li 1150 degree. Cov ntawv thov ib txwm muaj xws li qhov kub siab - kub thiab corrosive ib puag ncig xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom siv petrochemical.
Daim ntawv thov
253 MA S30815 stainless hlau tubing yog feem ntau siv nyob rau hauv ntau yam khoom uas yuav tsum tau muaj zog ntawm high kub, xws li tshav kub exchangers, kilns, chimney dampers, thiab qhov cub Cheebtsam.
