ALLOY 254 STAINLESS zitsulo

Aloyi 254 SMO ndi yokwera kwambiri, molybdenum ndi nitrogen alloyed super austenitic chitsulo chosapanga dzimbiri chokhala ndi mpweya wochepa. Imawonetsa kukana kwamphamvu kwa pitting, kuwonongeka kwa corrosion stress, komanso kutopa kwa dzimbiri yunifolomu. Aloyi 254 SMO ndi yamphamvu kwambiri kuposa magiredi wamba austenitic, ndi mphamvu pafupifupi kuwirikiza kawiri zitsulo zosapanga dzimbiri 300. Amadziwikanso ndi ductility mkulu ndi mphamvu mphamvu. Ndi kuchuluka kwa chromium, molybdenum, ndi nayitrogeni, Aloyi 254 SMO imagwiritsidwa ntchito pafupipafupi m'malo okhala ndi ma chloride ambiri, monga madzi amchere, madzi a m'nyanja, zomera za mphero za bleach, ndi mitsinje ina ya chloride. M'zinthu zina zapezeka kuti ndizotsika mtengo zolowa m'malo mwa nickel ndi titaniyamu.

254 SMO imagwiritsidwa ntchito pazotsatira izi:

1) Zida zogwiritsira ntchito madzi a m'nyanja, monga, kuziziritsa madzi a m'nyanja, mapaipi amadzi ozizira, machitidwe a madzi a ballast, machitidwe ozimitsa moto etc.

2) Machubu a Hydraulic ndi zida

3) Zipangizo mu zamkati bleaching zomera

4) Zigawo mu machitidwe oyeretsa gasi

5) Matanki ndi mapaipi amankhwala okhala ndi halide yapamwamba
