The chromium and molybdenum alloy metal in Alloy Steel A335 GR. P91 Pipes are well-known for their exceptional strength and temperature resistance. It has improved creep strength, making it ferritic with increased creep strength (CSEF). This alloy is normalized at 1050 degrees Celsius, then air-cooled to 200 degrees Celsius before being tempered at 760 degrees Celsius.

Alloy Steel P91 stands for its composition being 9% chromium and 1% molybdenum along with the addition of vanadium. The chromium present in this grade helps to increase temperature strength and oxidation resistance. The molybdenum increases the elasticity, resistance to wear and high temperature creep strength. This grade is virtually irreplaceable in resisting oxidation at elevated temperatures.

The molybdenum present in this alloy helps increase resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Molybdenum is also most effective for these pipes with increased high temperature creep resistance along with that, it also enhances the corrosion resistance of steel and resists pitting. P91 allows a wall thickness reduction by at least a 2:1 ratio. A wall that is thinner creates lighter hanger loads, less welding time and uses less filler metal.

These pipes go through several tests to ensure that they are safe to use, of good quality and durable. These pipes are popular in multiple industries like oil services, gas processing equipment, power generation industry, pressure boilers, petrochemical industry and other works which require high-temperature applications.
