Dab tsi yog SPA-H 1.8945 S355J0WP Siab zog huab cua steel phaj?
SPA H Steel, tseem hu ua weathering steel, yog siab -lub zog qis- alloy steel uas muaj kev tiv thaiv zoo rau atmospheric corrosion. Nws raug cais raws li qib qis- alloy structural steel, feem ntau alloyed nrog tooj liab, chromium, thiab npib tsib xee, uas ua rau nws cov khoom tshwj xeeb. Thawj cov ntsiab lus alloying hauv SPA H Steel txhim kho nws cov kav ntev thiab huab cua tsis kam, tso cai rau nws los tsim kev tiv thaiv patina thaum raug cov khoom. Qhov no patina tsim ib qho kev thaiv uas ua rau qeeb ntxiv corrosion, ua rau nws tsim tshwj xeeb rau kev siv sab nraum zoov.
SPA-H steel yog siab- zog, qis- alloyhuab cua steeluas ua raws li tus qauv kev lag luam JapaneseJIS G3125. Nws yog tsim los ua kom muaj zog tiv taus atmospheric corrosion los ntawm kev ua kom ruaj khov, tiv thaiv xeb -zoo li txheej ntawm nws qhov chaw thaum raug cov khoom. Cov cuab yeej no ua rau nws tsim nyog rau cov ntawv thov xws li kev tsim choj, kev tsheb ciav hlau, thiab cov thawv thauj khoom uas ntev - lub sijhawm ua haujlwm nyob rau sab nraum zoov yog qhov tseem ceeb.
SPA-H Corten steeldav siv nyob rau hauv huab cua preheater, economizer, railway carriage, ntim ntau lawm, choj tsev, kev tsim kho thiab hais txog.
