Abstract: Methods of forming low alloy steels and steels produced by such methods are provided. Various alloy additions and elements, as well as heating and tempering times and method steps are provided herein. Methods and materials of the present disclosure provide for enhanced fatigue at high hardness as compared with more brittle conventional steels.

Abstract: A railroad rail produced by rolling a substantially round bloom, together with a process and system for manufacturing the same. The round bloom may be produced by continuous casting methods. The bloom is initially rolled into a substantially rectangular shape and then into a rail. The rolling process may be continuous and in-line to allow for the production of very long seamless rails.

Abstract: A superior unitary one quarter mile long railroad rail and system and method for manufacturing the same. The method of manufacture is characterized by the use of a continuous rolling process and the in-line controlled cooling of the rail. The system produces very long rails without any weld seams.

Abstract: A superior unitary one quarter mile long railroad rail and system and method for manufacturing the same. The method of manufacture is characterized by the use of a continuous rolling process and the in-line controlled cooling of the rail. The long railroad rail is rolled in a single direction with a plurality of in-line rolling stations.

Abstract: A unitary one-quarter mile long railroad rail which is free of weld seams. The rail is produced via a process including continuous rolling and asymmetric cooling.

Abstract: A steel product having a combination of high strength and formability (as measured by percent tensile uniform elongation) is produced by austenitizing a steel consisting essentially of from 0.04 to 0.17% carbon, 0.8 to 2.0% manganese, up to 1.0% silicon, up to 0.12% vanadium, up to 0.1% columbium, up to an effective amount of titanium to form titanium carbonitrides, 0.001 to 0.025% nitrogen, balance essentially iron and then cooling at a rate of no more than about 70.degree. F/sec. to about 850.degree. F and at a rate of more than about 10.degree. F/sec. to transform the freshly formed austenite to a microstructure of from 10 to 35% by volume of martensite and/or lower bainite (MLB), balance essentially proeutectoid ferrite. Slower cooling rates may be employed to obtain the desired microstructure if a restricted chemical composition is used. The heat-treated steel product is characterized by an ultimate tensile strength of 80,000 p.s.i. minimum and a uniform elongation of 16% minimum.
