Stainless steel 1.4529, X1NiCrMoCuN25-20-7, Alloy 926, UNS N08926 resistant to intergranular corrosion
Incoloy 926 NAS255NM (UNS N08926 equivalent) is a high corrosion resistant stainless steel with high contents of chromium and molybdenum, and provides excellent corrosion resistance under severe environments such as high temperature seawater and flue gas desulfurization plants.
1.4529 grade is high alloyed stainless steel with an austenitic structure, which can be classified as nickel alloys (according to American standards).
Delivered in the supersaturated state exhibits resistance to intercrystalline, pitting, and stress corrosion, salt, sea water, chloride, sulfuric acid, phosphoric acid and other aggressive chemicals in high concentrations in liquid and gaseous form.
Materials of 1.4529 grade, except high chemical resistance, can work at elevated temperatures while maintaining adequate mechanical properties.
ASTM A276 UNS N08926 is a material grade specification for cold-finished or hot-finished bars in N08926 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes.

UNS N08926 Stud Bolt is widely used in chemical reactors, tanks, valves, pumps, and heat exchangers due to its resistance to acidic environments, particularly sulfuric acid and phosphoric acid.
Due to its excellent resistance to chloride-induced corrosion, N08926 stud bolts are commonly used in marine applications like offshore oil rigs, seawater systems, and shipbuilding.
N08926 stud bolt is used in desulfurization systems, gas turbines, and boilers, especially in environments subject to high temperatures and acidic condensates.
