ASTM A182 F22 UNS K21590 BLIND FLANGE ALLOY STEEL RF FACE B16.5

F22 is a material grade in ASTM A182, belonging to pearlite type heat strength steel, with good cold strain plasticity and machinability, and acceptable weldability. It is used for manufacturing main pipes with steam parameters up to 510 ℃, superheated pipes with pipe wall temperatures up to 540 ℃, and various elastic components that work at high temperatures.

Alloy Steel F22 Flanges certainly minimal use with hydrochloric acids. ASTM A182 Grade F22 Flanges performs much better than other austenitic stainless steel because of the much higher alloying of nickel as well as molybdenum. Thus, cheaper raw materials in Alloy Steel A182 Grade F22 WNRF Flanges, such as high – carbon ferrochromium, may be used in the initial melting operation. A182 F22 Alloy Steel Blind Flanges typically contains 11.5 percent to 18 percent of chromium and up to 1.2 percent carbon with nickel sometimes added. A182 F22 Steel Slip On Flanges are hardenable by heat treatment, have modest corrosion resistance. A182 Gr F22 Steel Flanges is an alloy that displays high resistance to corrosion, particularly against acidic environments.

Alloy steel flanges are divided into two categories: high alloy steel flanges and low alloy steel flanges.
Low alloy steel flanges are widely used in a wide range of industries due to their cost effectiveness. Low alloy steel flanges contain about 0.05 to 0.25% carbon and up to 2.0% manganese. Low alloy steels contain trace amounts of alloys such as niobium, nitrogen, vanadium, copper, nickel, chromium, titanium, calcium, molybdenum, rare earth elements, or zirconium.Low alloy steel flanges are widely used in military vehicles, construction equipment, ships, pipelines, pressure vessels, and oil drilling platforms.
High alloy steel flanges are widely used in various applications due to their structural components, automotive applications, chemical processing equipment, corrosion resistance, and excellent hardness. In order to strengthen chrome alloy flanges, elements such as copper, titanium, vanadium, and niobium are added to their alloys.

Advantages of Alloy Steel Flanges:

1. Corrosion resistance
2. Powerful components
3. High temperature and high efficiency
4. Heat dissipation performance
5. Durable
6. Tenacity
7. Lightweight
8. High tensile strength
