09crCusb (ND STEEL) tiv taus sulfuric acid tsawg kub corrosion tshuab (ND hlau, 09crCusb Hlau, 09crCusb Hlau, thiab lwm yam). Feem ntau hu ua 09 qws.
09crrcusb Nd steel yog hom tshiab ntawm cov hlau tiv taus sulfuric acid tsawg kub ntawm cov ntaub ntawv thiab xingcheng tshwj xeeb steel txij 1987 txog 1990
ND steel yog cov txheej txheem qis txheej txheem hlau. Piv nrog lwm cov hlau xws li cov hlau tsis tshua muaj carbon, corten thiab cr1a, nd steel muaj cov khoom zoo heev thiab cov khoom siv neeg kho tshuab.

Cov Khoom Siv
09crrcusb Seamless steel yeeb nkab siv tau nyob rau hauv kev tsim cov khoom lag luam uas cua sov, evapator thiab lwm yam khoom siv cua sov corrosion ntawm sulphur {}}}}} muaj cov roj flue.
Nws yog tus cwj pwm los ntawm kev tsis kam mus rau tsawg kub sulfuric acid did de liab point hauv qab no 200 degree.
Cov lag luam nqe ntawm cov sulfuric acid lwg point Resistant Cov Hluav Taws Xob Kub Li txog 9000
Thaum nws siv nyob rau hauv leej faj - nws muaj qhov nruab nrab, nws yog qhov tsis muaj tsawg dua li ntawm cov hlau uas tsis muaj zog, thiab tus nqi corrosion yog 3.481mg / cm2. H (34.81g / m2. H) hauv sulfuric acid daws ntawm 70℃thiab 50%.
Lub corrosion tsis kam ntawm nd steel (09crCusb) yog ntau tshaj 3 zaug uas 321 stainless hlau thiab 7 zaug ntawm 20G. Nws tuaj yeem pom tias ND steel yog thawj cov khoom xaiv rau kev sim tshuaj chemilique rau ib puag ncig ntawm sulphur {}}}}}}}}}}}}}}}}} muaj nruab nrab.
