Alloy Steel contains substantial quantities of elements other than carbon such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other commonly accepted elements such as manganese, sulfur, silicon, and phosphorous. Addition of such alloying elements is usually for the purpose to increase hardness, strength or chemical resistance.Pipes made of alloy steel have exceptional performance properties. These are generally developed for energy-related applications involving oil and gas drilling and are subjected to stresses in machine parts. Alloy Steel Tubes are also used in daily life, catering to the domestic, professional or industrial needs. In recent years, the demand for alloy steel tubing has been increasing along with the economic growth.

Type of Steel Pipes
Cold Drawn Steel Pipe
Hot Rolled Steel Pipe
Material & Manufacture
Pipe may be either hot finished or cold drawn with the finishing heat treatment noted below.
A / N+T
N+T / Q+T
Mechanical Tests Specified
Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test
For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested.
For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe.
Notes for Bend Test:
For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test.
Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser.
The bend test specimens shall be bent at room temperature through 180 without cracking on the outside of the bent portion.
