Letlapa la GH4169
1. Tlhaloso:
GH4169 ke setsi se matlafalitsoeng sa pula se sirelelitsoeng ka mocheso o phahameng o nang le ts'ebetso e ntle e felletseng mochesong.
mefuta e fapaneng ea -253 650C malapeng.
Matla a ho kotuloa a ka tlase ho 650C a maemong a pele har'a li-alloys tse holofetseng tsa mocheso o phahameng, 'me a na le matla a ho hanyetsa mokhathala, ho hanyetsa mahlaseli,
khanyetso ea oxidation, corrosion resistance, hammoho le ts'ebetso e ntle ea ho sebetsa le ho sebetsa hantle.
