09MnNiDR: belongs rau steel daim hlau rau cov hlab ntsha uas tsis tshua muaj siab.
"D" yog thawj tsab ntawv qis Pinyin thiab "R" yog thawj tsab ntawv ntawm Rong Pinyin.
09MnNiDR tus txheej txheem: normalizing lossis normalizing + tempering, quenching + tempering - 70 degree qis kub cuam tshuam.
09MnNiDR steel phaj siv: siv roj av thiab tshuaj siv tshuaj deethanizer towers, CO2 nqus yees, nruab nrab siab flash evaporation yees, coolers, deethanizer towers, reabsorption yees, compressor casings, propane cryogenic cia tso tsheb hlau luam, thiab lwm yam. Petrochemical khoom, chaw nres tsheb fais fab, boilers thiab lwm yam kev lag luam. Nws yog siv los ua cov khoom siv thiab cov khoom siv xws li reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum cylinders, high-pressure water pipes in hydropower stations, turbine volutes, thiab lwm yam.
Cov teeb meem tsis zoo rau kev siv xws li tawg, npuas, folds thiab inclusions tsis raug tso cai rau saum npoo ntawm cov hlau phaj. Yuav tsum tsis txhob delamination ntawm steel phaj.
