	Aero 22 - Maintenance of High-Stregth Alloy Steel Components
		Although high-strength alloy steels are hard and resist dents, scratches, and nicks, stress concentrations caused by mechanical damage can dramatically reduce the service life of a component.
		Hydrogen embrittlement occurs when a high-strength alloy steel component absorbs hydrogen, which is not removed in a timely manner in accordance with the SOPM (e.g., embrittlement relief baking).
		High-strength alloy steel components should be stripped completely during overhaul (including removal of bushings and bearings in all structural components).

	Quenched and Tempered Low-Alloy Steel
		Alloy steels are defined as those steels that: (1) contain manganese, silicon or copper in quantities greater than the maximum limits (1.65% Mn, 0.60% Si, and 0.60% Cu) of carbon steel; or (2) that have specified ranges or minima for one or more other alloying additions.
		The austenite grain size of hot-rolled steels is determined by the recrystallization and grain growth of austenite during rolling.
		Like niobium and/or vanadium steels, titanium microalloyed steels are strengthened by mechanisms that involve a combination of grain refinement and precipitation strengthening; the combination depends on the amount of alloy additions and processing methods.

	Plain-carbon steel - Wikipedia, the free encyclopedia
		Plain-carbon steel is a metal alloy, a combination of two elements, iron and carbon, where other elements are present in quantities too small to affect the properties.
		Steels are often wrought by cold-working methods, which is the shaping of metal through deformation at a low equilibrium or metastable temperature.
		Quenching: Plain-carbon steel with at least 0.4 wt% C is heated to normalizing temperatures and then rapidly cooled (quenched) in water, brine, or oil to the critical temperature.

	Strengthening mechanisms in alloy steel
		Although alloying elements affect hardenability, they have a minor effect on hardness except to reduce it at high carbon levels by causing austenite to be retained.
		The fully austenitic steel is severely warm-worked above the lowest temperature at which martensite is produced during the straining.
		The amount of martensite is influenced by alloy composition and increased with deformation and lowering of the temperature.

	alloy steel - Toseeka Search Results
		Steel is sometimes described as a sea of electrons.
		A more recent definition is that steels are iron-based alloys that can be plastically formed (pounded, rolled, etc.).
		Even in the narrow range of concentrations that make up steel, mixtures of carbon and iron can form into a number of different structures, or allotropes, with very different properties; understanding these is essential to making quality steel.

	08/04/2000 - Alloy steel chain slings must not be loaded beyond working load limit.
		This is in response to your October 17, 1999, letter to the Occupational Safety and Health Administration (OSHA) in which you ask a question relating to the requirements of using alloy steel chains for material handling.
		Therefore, the standard mandates that only alloy steel chain be used, and that such chain meet the Table H-1 rated capacities.
		Therefore, steel alloy chain of less than Grade 80 can only be used if it meets the capacity requirements listed in 29 CFR 1926.251.

	HSLA steel - Wikipedia, the free encyclopedia
		HSLA steels are therefore also referred to as "microalloyed", as they are indeed alloyed in extremely small amounts by comparison to other main commercial alloy steels.
		These added elements are intended to alter the microstructure of plain-carbon steels, which is usually a ferrite-pearlite aggregate, to produce a very fine dispersion of alloy carbides in an almost pure ferrite.
		HSLA steels are also more resistant to rust then most carbon steels, due to their lack of pearlite - the fine layers of ferrite (almost pure iron) and cementite in pearlite.

	alloy vs. steel wheels - NissanForums.com
		Alloy wheels are much stronger than steel wheels, and much lighter.
		Alloys can be lighter than steel assuming that a lightweight alloy is used.
		Again, for typical use the alloy versus steel comparison really does not matter (steel wheels may have an advantage for competition in that they can be sliced and diced to make custom widths and offsets for serious competitors).
