00Cr12Ni8Cu2TiNb (Custom 455) chemical composition

？

Custom 455 stainless steel is a versatile, high-strength alloy that has been used in a variety of applications. It is composed of 19.5 – 20.5% chromium, 12.0 – 13.0% nickel, 2.00 - 2.50% copper, 0.50 – 0.80% niobium, and 0.10 – 0.30% titanium. With its blend of elements, it is able to achieve superior corrosion, heat, and wear resistance qualities that are not found in other alloys.

Custom 455 is a martensitic alloy, and can consequently be quenched, aged, heat treated, and cold worked. It is machinable and work hardens, and cutting speeds can be conducted at around 20% to 30% slower than carbon steels. As it contains nickel, it is much more resistant to oxidation at high temperatures, and can be exposure to temperatures around 1000°F without showing any significant signs of corrosion.

The blend of elements also ensures Custom 455 is extremely resistant to corrosion in a variety of environments, and this is why it is a favorite in the medical industry. The material has excellent galling resistance and is able to withstand a variety of chemicals and chloride-ion-containing environments, making it a popular choice in the production of surgical equipment, instruments, and fasteners.

Custom 455 is also prized for its attractive appearance, thanks to its moderate amount of titanium. During hot working operations, the titanium combines with nitrogen to form an attractive, blue finish on the material. This paired with the bright polish makes for a visually attractive finish for any dental applications or instruments.

In addition, Custom 455 is an ideal choice for components that require constantly changing and varying temperatures. It is exceptionally resistant to thermal shock, and offers superior performance in hotter temperatures, which makes it a popular material for jet engine blades, jet turbines, and turbocharger rotors.

Whether its being used in the medical industry or in jet engines, Custom 455 is an incredibly versatile steel, capable of withstanding a range of temperatures, corrosive environments, and wear-and-tear. Its blend of elements, paired with its ease of machining, makes for an all-around reliable and high-performing alloy.

Custom 455, is a martensitic stainless steel, with a combination of good corrosion resistance and strength similar to Alloy 400. It features an alloy content which includes 12% nickel, 2% molybdenum, 8% chromium and 2% titanium. The combination of these elements give Custom 455 its unique properties, making it a popular choice for many applications.

The high level of corrosion resistance in Custom 455 make it suitable for use in a range of environments. In addition to this, it offers a good resistance to stress corrosion cracking, making it ideal for processes that require a safe service temperature. As with any stainless steel, it is important to ensure that it is properly looked after to ensure the highest levels of performance and a long lasting service life.

The superior hardenability of Custom 455 gives it an above average resistance to wear and tear, making it suitable for applications which require greater strength. Its machinability ratings also make it an ideal material for moulded, cold-drawn and machined components.

The combination of properties makes Custom 455 an ideal choice for use in a variety of industries and applications, including tooling, medical instruments, nuclear components, and nuclear fuel applications. Its excellent formability and free machining capabilities make it a popular choice for manufacturing and machining operations.

Overall, Custom 455 is a corrosion resistant, high strength, and hardenable stainless steel, ideal for use in a variety of industries and applications. Its combination of properties makes it a popular choice for both its strength and corrosion resistance.
