    The primary use of high-strength aluminum alloys is in aircraft construction; the airframe of modern aircraft is approximately 80 percent aluminum by weight (Marceau, ). Traditionally, the structural aluminum alloys in aircraft have been in damage-critical areas and in strength-critical areas (Starke and Staley, ). maraging steels, and titanium. Paul M. Novotny* and Gernant E. Maurer* Carpenter Technology Corp., Wyomissing, Pennsylvania T he range of ultra-high-strength steels with good toughness has expanded in recent years to allow more alloy choices. In ad-dition to maraging steels, another family of ultra-high strength steels that possess out-.

    Aircraft Quality - is the most commonly specified quality for general aerospace uses. Special Aircraft Quality - places minimum values on ductility in the transverse direction. Premium Aircraft Quality - The ultimate quality that can currently be obtained in production amounts and is usually applied to the most critical parts and components. Ultra-high-strength steels have been in use for only a few years since grades with a tensile strength of over N/mm² are, for the most part, not yet available in a constant quality. Categories include the following: Dual phase (DP) steels Dual phase steels belong, like TRIP steels and complex phase steels, to the multi-phase steel category.

Welding is an important process in the fabrication of parts. beams and panels are additional uses of these steels. The choice of a specific high-strength steel depends on a number of application requirements including thickness reduction, corrosion resist-ance, formability, and weldability. For many applications, the most impor-tant factor in the steel selection process is the favorable strength-to-weight.

The ultrahigh-strength steels used in aerospace applications are primarily alloys developed 25 or more years ago, which would seem to illustrate the conservatism of alloy : Warren M. Garrison. The ultrahigh-strength steels used in aerospace applications are primarily alloys developed 25 or more years ago, which would seem to illustrate the conservatism of alloy producers.

However, the now widespread use of AF, which was developed in the mids, suggests that new alloys will be adopted for aerospace applications if their mechanical properties are markedly Cited by: XD15NW ferrous alloys. Pyrowear is a high strength stainless steel designed for gear application.

Aermet is an ultra high strength steel which has potentials for gear application. C61 and C64 are secondary hardening grade gear steels, products of QuesTek’s Computational Design, Development and Application of HighPerformance Gear.

high strength and ultra high strength steels with up to MPa tensile strength. These steel grades are suitable for cold forming of structural and safety-related automotive components. The high strength level gives potential for considerable weight reduction and a cost-effective way to produce energy efficient Size: KB.

Dr Tapas Kumar Roy is a Principal Scientist in the Research and Development (R&D) Division of Tata Steel Limited in Jamshedpur, India. He holds M. Tech and PhD degrees from the Indian Institute of Technology Kanpur, India.

Dr Roy has been associated with Tata Steel for over 20 years and during this period he has worked in various functions like Scientific Services, Long Product Technology. The Ni-Co-Mo family of steel has been designed with idea to develop high proof stress with optimum toughness for various strength levels.

In contrast to conventional ultra- high strength alloy steels in which carbon martensite is necessary for the development of high strength, 18 Ni maraging steel have a very low carbon content and their high File Size: KB. High Strength Steel Grades: High Strength Steels(HSS) are defined as steels with yield strength from MPa.

Ultra High Strength Steels(UHSS) reach yield strength above MPa. The high strength steels grades include interstitial free(IF), brake hardenable(BH), carbon -Mn(C Mn), dual phase(DP), complex phase(CP), martensitic steel(MP.

steel industry can offer their customers a large variety of high strength and ultra high strength steel grades which fit best to the respective appropriate application [e.g. 1, 2]. Figure 1 gives an overview of the high and ultra high strength hot rolled steel grades for direct processing produced atFile Size: 1MB.

• High carbon steels: Thanks to the high carbon content of % to %, this type of steel enjoys very high hardness after heat treatment. But it has very less application in aircraft industry, except for flat and coil springs. Mechanical and technological properties of ultra high strength Optim steels • 3.

Cold formability Flanging in a brake press to relatively small inside bend radii is possible, but due to the very high strength of the material the equipment must be capable of handling suf-ficiently high loads and the tooling must be of high qual-ity. These steels are used largely in the aircraft industry for ultra-high-strength structural applications.

They have carbon in the low to medium range and possess good fracture toughness at high-strength levels. In addition, they are air hardened, which reduces the distortion that is encountered with more drastic quenching methods.

CarTech Custom stainless is a premium melted, martensitic, age hardenable alloy capable of ksi ( MPa) UTS when aged at ºF (H condition) – which is 20% higher strength than possible with traditional stainless steels and is currently covered by the.

Conventional low- to high-strength steels include mild, interstitial-free, bake-hardenable, and high-strength low-alloy steels. They have simpler structures and have been widely used for many years.

At the beginning of the s, ultra high-strength steels of the TSMPa grade and higher were studied. The Hot Forming process allows for the formation of shapes that cannot be cold stamped with Ultra High Strength steels. The unique properties of this material combine both complexity and strength – and components made with press-hardened steel can accomplish in one piece what would usually require heavier, thicker parts that are welded together.

High-strength low-alloy steels (HSLA steels) High-strength low-alloy steels are proprietary steels manufactured to SAE or ASTM with carbon max. %, manganese max. % and such other alloying elements as will give the minimum yield point prescribed for various thicknesses ranging between 12 and 60 mm.
