A286 is an age-hardenable iron base superalloy for applications requiring high strength from -320°F up to 1000°F long time, 1300-1500°F short time. Oxidation resistance is high for continuous service to 1500°F, intermittent to 1800°F. Aqueous corrosion resistance is comparable to 316L stainless. A286 is used for reasonably low cost when moderate strength and oxidation resistance are required at temperatures greater than suitable for stainless steels. Applications for A-286 are, Jet engine components, high temperature fastners, springs, non-magnetic cryogenic equipment and gas turbines.

Alloy 4140 is an oil-hardening steel of relatively high hardenability. Its chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. C4140 responds well to heat-treatment and is comparatively easily machined in the heat-treated condition. With a combination of such highly desirable properties as good strength and wear resistance, excellent toughness, coupled with good ductility, and the ability to resist stress at elevated temperatures. Typical applications for 4140 alloy steel include shafts, gears, bolts, couplings, spindles, tool holders, sprockets, hydraulic machinery shafts, oil industry drill collars,kelly bars, tools joints.
