Duplex Steel Valve Supplier in Australia

Australian Valve is a famous Duplex Steel Valve Supplier in Australia.Duplex steel valves are industrial valves made from a type of stainless steel known as duplex stainless steel. It is known by its dual-phase microstructure, consisting of both austenite and ferrite phases. This combination provides several advantages, including high corrosion resistance, good mechanical properties, and excellent toughness. It is a corrosion-resistant alloy that combines the desirable properties of both austenitic and ferritic stainless steels. These valves are used in a variety of industries where corrosion resistance, strength, and durability are essential. These offer superior resistance to various types of corrosion, including pitting and crevice corrosion, stress corrosion cracking, and general corrosion caused by chloride-containing environments. These have a high tensile strength and can withstand high pressures and temperatures. These can operate effectively over a wide temperature range, from cryogenic temperatures to elevated temperatures, depending on the specific alloy composition.
