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 somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%. Most commonly, the phrase "Alloy Steel " refers to low-alloy steels.
Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). However, the term "Alloy Steel " is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead and zirconium.
The following is a range of improved properties in alloy steels (as compared to carbon steels): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and hot hardness. to achieve some of these improved properties the metal may require heat treating.

ASTM A691 / ASME SA691 Alloy Steel EFW Pipes
Carbon and Alloy Steel Pipe Electric Fusion Welded for High Pressure Service at High Temperatures
This specification covers steel pipe, electric-fusion-welded with filler metal added, fabricated from pressure-vessel quality plate of any of service analyses and strength levels and suitable for high-pressure service at moderate temperatures. Heat treatment may or may not be required to attain the desired properties or to comply with applicable code requirements. Supplementary requirements are provided for use when additional testing or examination is desired.
The specification nominally covers pipe 16 in. (405 mm) in outside diameter or larger with wall thicknesses up to 3 in. (75 mm), inclusive. Pipe having other dimensions may be furnished provided it complies with all other requirements of this specification.
Several grades and classes of pipe are provided. Grade designates the type of plate used.
class designates the type of heat treatment performed during manufacture of the pipe, whether the weld is radiographically examined, and whether the pipe has been pressure tested as listed
Savoy Piping Inc. stocks a full range of the following A691 / SA691 pipe grades.

A Requires quenching and tempering
B 9 CR steel is an air-hardenable steel, at times retaining down to near atmospheric temperature. Good practice is to allow the steel to cool to 15 F or Lower before subjecting the steel to a tempering treatment or post-weld heat treatment.
