Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

A335 P22 Chromium Pipe contains chromium in its composition to provide high corrosion resistance. There are other elements in the material composition of P22 steel pipe. Molybdenum is a common addition in all A335 grades. Manganese, phosphorus, silicon and carbon are added according to different grades.

High alloyed types of steel are favored in the plumbing industry for use in extreme conditions, be it hot or cold, or subjected to rough service. This is because a combination of chemistry and proper heat treatment can result in a strong and flexible pipe that can withstand blows. Alloy pipes are often favored by the oil and gas and power generation industries due to their toughness.

ASTM A333 is a standard specification for seamless and welded carbon and alloy steel pipes for low temperature service or other applications requiring notch toughness. This standard covers several grades of ferritic steels: Grade, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11. Metals-Piping offers welding processes by seamless or no filler metal added in the welding operation, but Grade 4 shall be manufactured by seamless processes only. Pipes should be free of welding repairs, either by radiographic or ultrasonic testing.
