Alloy Steel Pipe is used in applications which require moderate corrosion resistance properties with good durability and at an economical cost. … There are two classes of alloy steels - high alloys and low alloy steels.

About Low alloy piping materials are often called chrome moly materials because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Chromium increases the hardness and strength and only minimally reduces elasticity. Molybdenum improves tensile strength and especially heat resistance.

3.2. 1.2 Grades of steel used

Pipe grade and yield strength	Pipe wall thickness required (in.)	MAWP (psi)
Grade B (35,000 psi)	0.337	3774
Grade X-42 (42,000 psi)	0.237	3185
Grade X-46 (46,000 psi)	0.219	3219
Grade X-52 (52,000 psi)	0.188	3120

The two types of pipes produced through these technologies are longitudinal-submerged arc-welded (LSAW) and spiral-submerged arc-welded (SSAW) pipes. LSAW are made by bending and welding wide steel plates and most commonly used in oil and gas industry applications.
