00Cr12Ni8Cu2TiNb (Custom 455) steel grade introduction

Custom 455 is a martensitic stainless steel, specifically designed to be used in applications that require wear and galling resistance, along with good corrosion and oxidation resistance. Custom 455 is an improved version of Type 410, and has been developed to be used in applications requiring maximum strength, high wear and galling resistance and high corrosion resistance. These properties are achieved by using a combination of high chromium (12%) and molybdenum (2%) content, along with additional elements like nickel (8%), copper (2%), titanium (Nb) and nitrogen.

Custom 455 has excellent wear and galling resistance, due to the high levels of combined molybdenum and chromium. This combination of elements gives the steel a martensitic microstructure, which helps to produce its excellent wear and galling properties. The high chromium content also gives the steel excellent corrosion resistance to both acidic and neutral solutions. In addition, the additional nickel and copper content provides further corrosion protection.

Custom 455 is a hardenable stainless steel, allowing it to be hardened by heat treatment and thus increasing its strength and wear resistance. However, this process can also be used to reduce the steel’s wear properties, so it is important to perform the correct heat treatment when using Custom 455. The steel can also be cold worked to increase its strength and wear resistance. Cold working also helps to reduce the impact of any microstructural changes in the steel, which can cause a loss in its mechanical properties.

In terms of welding, Custom 455 can be welded using the traditional methods of shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding. Although the steel can be austenitized to an appropriate temperature, post-weld heat treatment is generally not necessary.

In general, Custom 455 is appropriate for use in applications that require maximum strength and wear resistance. Its combination of chromium and molybdenum gives the steel excellent wear and galling resistance, while its additional elements provide good corrosion and oxidation resistance. Its hardenable qualities also make it suitable for many applications. As such, Custom 455 can be used for components of refrigeration systems, earth-moving machinery, cutting tools and medical instruments.

Custom 455 is a type of high-strength stainless steel alloy with excellent corrosion and wear resistance. This alloy has very good strength and can be machined, formed, and welded to a variety of shapes. It has excellent corrosion resistance in both acidic and basic environments and can withstand temperatures up to 1400 degrees Fahrenheit. It also provides outstanding resistance to wear and has been used in high temperature aerospace, power generation and medical applications. Custom 455 stainless steel is especially resistant to pitting and crevice corrosion, making it an ideal material for applications exposed to extreme environments as well as highly corrosive materials, such as hydrofluoric acid, phosphoric acid, and sulfuric acid.

Custom 455 steel has especially high levels of chromium, nickel, and silicon. The addition of high levels of chromium provides increased surface hardness, resistance to oxidation and tarnish, and provides exceptional corrosion resistance. The addition of niobium provides strength and wear resistance. The addition of two percent copper adds chic weldability and provides excellent thermal and electrical conductivity. The addition of titanium further increase the corrosion resistance and also adds ductility and improved machinability.

Overall, Custom 455 has many advantages that provide it with a wide range of uses. Because of its corrosion and wear resistance, this alloy is especially useful in applications that require excellent heat resistance, wear and corrosion resistance, and strength. Its unique properties make it an ideal material for aerospace, medical, and power generation applications.
