Icwecwe leGH4169
1. Ingcaciso:
I-GH4169 yimvula eyomeleziweyo isiseko esikhuselweyo kubushushu obuphezulu kunye nokusebenza kakuhle okubanzi kwiqondo lobushushu.
uluhlu lwe -253 650C ngaphakathi.
Amandla esivuno angaphantsi kwe-650C aqala phakathi kwe-alloys enobushushu obuphezulu, kwaye anokumelana nokudinwa, ukuxhathisa kwimitha,
ukuxhathisa kwi-oxidation, ukumelana nomhlwa, kunye nokusetyenzwa kakuhle kunye nokusebenza kwewelding.
2. Ibakala elilinganayo:
Inconel 718, UNS NO7718 (USA), NCI9FeNb (France), W. Nr. 2.4668 (eJamani)
