seamless steel raj rau anti-acid tsawg
kub dew point corrosion
ND steel yog ib qho tshiab-style low alloy structural steel. Piv nrog rau lwm cov hlau, xws li cov pa roj carbon tsawg, Corten, CR1A, ND steel muaj kev tiv thaiv zoo heev thiab cov khoom siv kho tshuab. Cov txiaj ntsig tau pom tias nyob rau hauv aqueous tov ntawm vitriol, hydrochloric acid thiab sodium chloride, corrosion kuj ntawm ND steel yog siab dua carbon steel. Qhov tseem ceeb tshaj plaws yog tias nws muaj peev xwm tiv thaiv acid dew point corrosion. Los ntawm sab hauv tsev mus rau 500 ℃, cov cuab yeej cuab tam ntawm ND steel yog siab dua cov pa roj carbon steel thiab khov kho, cov cuab yeej vuam zoo heev. ND steel feem ntau yog siv los tsim cov khoom lag luam, cov khoom siv hluav taws xob thiab cov cua kub cua sov. Los ntawm 1990s, ND steel yog dav siv nyob rau hauv kev lag luam ntawm petrifaction thiab hluav taws xob fais fab.
