Chitsulo chosapanga dzimbiri
Short Description:
Stainless steels generally contain between 10-20%chromium as the main alloying element and are valued for high corrosionresistance. With over 11% chromium, steel is about 200 times moreresistant to corrosion than mild steel. These steels can be divided into three groups based on their crystalline structure: Austenitic: Austenitic steels are non-magnetic and non heat-treatable, andgenerally contain 18% chromium, 8% nickel and less than 0.8% carbon. Austenitic steels form the largest porti...

Steels zosapanga generally contain between 10-20%
chromium as the main alloying element and are valued for high corrosion
resistance. With over 11% chromium, steel is about 200 times more
resistant to corrosion than mild steel. These steels can be divided into
three groups based on their crystalline structure:
-
Austenitic :
steels Austenitic si a maginito ndipo sanali kutentha n'ngochiritsika, ndi
zambiri zili ndi 18% chromium, 8% faifi tambala ndi zosakwana 0,8% mpweya. Steels Austenitic
kupanga gawo lalikulu kwambiri padziko lonse msika zosapanga dzimbiri ndipo
kawirikawiri amagwiritsidwa ntchito zida processing chakudya, ziwiya khitchini ndi piping. -
Ferritic : steels Ferritic muli kufufuza ndalama ya faifi tambala, 12-17% chromium, zosakwana 0.1% mpweya, pamodzi ndi zinthu zina alloying, monga molybdenum, zotayidwa kapena titaniyamu. Izi steels maginito sangathe anaumitsa ndi kutentha mankhwala, koma mukhoza kulimbikitsidwa ndi ntchito ozizira.

Martensitic :
Martensitic steels muli 11-17% chromium, zosakwana 0.4% faifi tambala ndipo
mpaka 1.2% mpweya. Steels izi maginito ndi kutentha n'ngochiritsika ntchito
mipeni, kudula zipangizo, komanso zida mano ndiponso opaleshoni.
