BL Flat Face Blind Flange 24 Inch ANSI B16.5/B16.47 Alloy Steel Wear Resistant

ASTM A182 F1 F5 F9 F11 F12 F22 F91 ANSI B16.5/B16.47 BL Alloy Steel Blind Flange

Alloy steel is a type of steel alloyed with several elements such as molybdenum, manganese, nickel, chromium, vanadium, silicon, and boron. According to the different added elements and appropriate processing techniques, alloy steel can obtain special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties. Those have less than 5% alloy elements is are categorized as low alloy steel, these have alloy elements ranging from 5%-10% are categorized as minimum alloy steel, those have more than 10% alloy elements are categorized as high alloy steel.

Flanges made of alloy steel are widely used in water lines, oil, and gas, chemical plants, food production systems, etc. where high corrosion resistance, high temperature resistance and high pressure resistance are required.
