Overview
MP35N is a precipitation-hardenable nickel-cobalt-chromium-molybdenum alloy renowned for its exceptional strength, hardness, and outstanding corrosion resistance, particularly at elevated temperatures. This alloy combines ultra-high tensile strength, toughness, and ductility, while offering superior resistance to fatigue and stress corrosion cracking. It performs exceptionally well in harsh environments such as hydrogen sulfide, saltwater, chloride solutions, and seawater.
As a non-magnetic material, MP35N achieves ultra-high tensile strength through work hardening and aging processes. Its remarkable durability and versatility make it an ideal choice for demanding applications, including medical devices, dental products, electrical components, springs, and instrument parts in medical fields.
