BÖHLER L303 is a corrosion and heat resistant nickel alloy in the form of bars, forging and forging stock. The alloy’s high-temperature strength is derived from its solid solution strengthening elements of molybdenum, cobalt, and chromium, and its age-hardening elements, aluminum and titanium. Its strength and stability ranges are higher than those typically available for Alloy 718. It is widely used typically for rotating parts, such as compressor and gas turbine blades, disks, hubs, shafts bolts and spacers requiring high strength up to 1500°F (816°C) and oxidation resistance up to 1750°F (954°C) but usage is not limited to such applications.

BÖHLER L625 is a non-magnetizable corrosion and heat resistant nickel alloy in the form of bars, forgings and semi-finished products up to max 254 mm diameter/ cross-section and oxidation resistant up to 1093°C.

High duty parts and components for gas turbines, aerospace engines, high-speed airframe parts such as disks, buckets, spacers and high temperature bolts and fasteners. Compared to standard alloy 718 AMS limits, Cb in L718HCb is adjusted in the upper range of the standard limits in order to enhance mechanical properties. L718HCb is typically used for high temperature bolting and fasteners.

BÖHLER LHX is a corrosion and heat resistant nickel alloy in the form of bars, forging and forging stock. Resistant to oxidation up to 2200°F (1204°C) and high strength above 1500°F (816°C). It is widely used typically for parts, in engines especially for combustion chambers, after burners and exhaust components but usage is not limited to such applications.

BÖHLER N695 is a Chromium alloyed stainless steel with high hardness, wear resistance and good corrosion resistance in the hardened and tempered condition. this grade is typically used for parts requiring hardness up to 58 HRC and resistance to wear, corrosion, and oxidation, e.g. balls, rollers, needles and rings for corrosion resistant bearings, but usage is not limited to such applications.

BÖHLER N695SA is a high-grade, vacuum remelted chromium stainless steel of aerospace quality, offering high hardness, wear resistance, and good corrosion resistance in the quenched and tempered condition. Compared to air-melted quality, this steel exhibits improved rolling contact fatigue properties and is typically used for components requiring hardness up to 58 HRC and resistance to wear, corrosion, and oxidation—such as balls, rollers, needles, and rings for corrosion-resistant bearings—although its use is not limited to these applications.

BÖHLER R100 ia a a premium aircraft-quality, vacuum-arc-remelted low-alloy steel in the form of bars, forgings and forging stock. The grade is used typically for parts requiring through hardening properties, usually with hardness of approximately 60 HRC in section thicknesses 0.50 inch (12.7 mm) and under. E.g. bearing rings and rolling elements, bearing balls and races.

BÖHLER R250 is a a premium aircraft-quality, double vacuum-melted low-alloy steel in the form of bars, forgings and forging stock. The grade is used typically for parts such as bearings operating under heavy loads and high speeds at moderate temperatures up to 600° F. E.g. bearings and rolling elements, bearing balls and races.

BÖHLER R350 is a premium aircraft-quality, double vacuum-melted low-alloy steel in the form of bars, forgings and forging stock. The grade is used typically for critical carburized parts such as bearings operating under heavy loads and high speeds at moderate temperatures. E.g. bearings and rolling elements, bearing balls and races.

Components featuring elevated high-temperature strength for use in thermal engines and power plants, such as turbine blades, turbine discs, screws, bolts, pins and shafts.

BÖHLER V358 in the British Standard Aerospace Series is a 3% Cr-Mo-V nitriding steel offering a tensile strength of 1,320-1,470 MPa, combined with excellent hardenability for high core strength and develops a hard wear resistant case after surface treatment. The alloy is produced by vacuum arc remelting. (VAR) Typical applications are gear shafts and crankshafts with maximum diameter of 70mm for the aircraft industry and automtovie components.

BÖHLER V361 is a 3% Cr-Mo-V nitriding low-alloy steel of premium aircraft-quality, low-alloy steel offering a tensile strength of up to over 1350MPa in the form of bars, forgings, and forging stock. Due to the optimized production route via VIM-melting and VAR-remelting, the steel offers high impact strength and fatigue limit. It may be nitrided in the heat treated condition to obtain a wear resistant surface. It is used typically for nitrided parts such as bearings, operating under heavy loads and high speeds at moderate temperatures, and requiring highest surface hardness, high core toughness, and less distortion than parts made from case hardening steel, but usage is not limited to such applications.

Highly stressed components for the aircraft and rocket industries. Constructional and tool steel for hot and cold working tools used for long-time service at temperatures up to approx. 450°C (840°F).
