Alloy Steel flanges Alloy steel flanges are known for their high strength, durability, and corrosion resistance, which makes them a popular choice for various industries, including oil and gas, chemical, and petrochemical industries. At Bullion Pipes, we are a leading manufacturer and supplier of alloy steel flanges. Our flanges are made from the highest quality materials and are designed to meet the strictest industry standards.
Alloy steel flanges are mainly made up of chromium, molybdenum, and nickel composition along with other products. These flanges show excellent corrosion and oxidation resistance. They are widely used in water lines, oil, and gas, chemical plants, food production systems, etc.
Alloy steels are classified into two categories, high alloy steel and low alloy steels. While Low Alloy Steel Flanges contain about 0.05 – 0.25% of carbon along with up to 2.0% manganese. Low alloy steels contain trace quantities of alloyants such as niobium, nitrogen, vanadium, copper, nickel, chromium, titanium, calcium, molybdenum, rare earth elements, or zirconium. In order to strengthen the Chromium AS Flanges, its alloy has added elements i.e. Copper, titanium, vanadium, and niobium.
There are different face such as flat face, raised face and ring type joint flanges. The Alloy steel lap joint flange is a special type that it has a lap on it. The flanges are used in various industrial applications to hold the pipes together. There are different manufacturing types such as the Alloy Steel Forged Flanges, welded flanges, screwed flanges and threaded flanges. The different types are useful under different scenarios. The forged flanges are made from a single piece of raw material.
