Super austenitic hlau ASME SA213 · S31254.SMO254 yeeb nkab Duab tshwj xeeb

Cov hlau super austenitic ASME SA213 · S31254.SMO254 yeeb nkab

Kev Piav Qhia Luv:

254 SMO (UNS S31254) yog cov hlau stainless austenitic uas sib xws nrog lwm cov hlau stainless austenitic thiab tsim nrog cov chromium, molybdenum, thiab nitrogen ntau rau qhov siab tshaj plaws pitting thiab crevice corrosion tsis kam. Cov alloy no feem ntau yog chromium-molydenum-nickel alloy nrog nitrogen ib txwm ua ib qho ntxiv; qhov kwv yees sib xyaw yog: Cr 20% -22%, Mo 6% -7%, Ni 18% -20%, thiab nitrogen ua rau nws lub zog thiab corrosion tsis kam, tshwj xeeb tshaj yog nyob rau hauv chloride-bearing ib puag ncig xws li hauv dej hiav txwv, ua haujlwm hauv ntawv, pulp, thiab tshuaj lom neeg kev lag luam.
