What are ASTM A182 Gr F91 Alloy Steel Bars?

ASTM A182 Grade F91 Alloy Steel Bars are forged or rolled materials composed of chromium-molybdenum-vanadium steel. F91 is a member of the ferritic steel category intended to retain mechanical integrity in a prolonged exposure to high temperature. The bars adhere to the specifications of ASTM A182 that include forged or rolled alloy and stainless steel pipe flanges and fittings, valves, and parts to be used in high-temperature applications.

One of the key strengths of ASTM A182 Gr F91 Alloy Steel Bars is their superior creep resistance. This ensures that they do not suffer structural weakening even in high-temperature environments like thermal power facilities and refineries. They possess great tensile strength, resistance to corrosion and oxidation, and toughness, all of which are essential in cases where mechanical stress and resistance to oxidation are not negotiable. Their low thermal expansibility reduces dimensional changes during heating, thus enabling superior working in precision applications.
