1. Brief introduction:

   Alloy 25-6HN is a super-austenic stainless steel contain 6% Mo with N to enhangxe properties.

   It owns thermal stability and resistance to stress corrossion cracking due to higher Nickel content compared to stainless steel.

   It has significantly improved strength and corrossion resistance in most environments over conventional austenitic stainless steels.

   Mainly used in heat exchangers for chemical processing and marine applications and desalination systems, flue gas desulfurizationn equipment for coal-fired power plants and reaction vessels for pharmaceutical production.
