Introduction to steel grade of austenitic precipitation hardening stainless steel 0Cr15Ni25MoTiAlVB (A-286)

A-286 (0Cr15Ni25MoTiAlVB) stainless steel is a precipitation-hardened stainless steel that provides a combination of high strength and good corrosion resistance. A-286 stainless steel is used in industrial applications such as turbine blades, fasteners, valves, and shafts. The alloy has a high chromium content, which makes it highly resistant to corrosion and oxidation. Additionally, it is precipitation-hardened and has a high tensile strength that makes it well suited for many demanding applications.

A-286 (0Cr15Ni25MoTiAlVB) stainless steel is a precipitation-hardening stainless steel that combines high strength and excellent corrosion resistance. This grade has a typical composition of 15% chromium, 25% nickel, and 7% molybdenum. It provides a wide range of properties such as high hardness at a given strength, and the ability to remain ductile at temperatures as low as -200°C. This grade of stainless steel is renowned for its ability to maintain consistent strength and corrosion resistance in elevated temperatures due to their precipitation hardening and hardening capability.

A-286 stainless steel is often used in fastening applications such as bolts, nuts, and rivets. This grade has a high strength-to-weight ratio, making it suitable for many items that require lightness and strength. Additionally, its ductility and toughness make it suitable for items that require durability, such as valves and turbochargers.

A-286 stainless steel also has outstanding thermal properties, so it can be used for items that require long exposure to elevated temperatures. This makes it an ideal material for components of aircraft, such as dryers, turbines, and fan blading, as well as components of marine equipment, such as heat exchangers and turbine shafts.

A-286 (0Cr15Ni25MoTiAlVB) stainless steel has a high resistance to corrosion by reducing environments as well as a good general corrosion resistance in oxidizing and neutral atmospheres. In addition, its high chromium content provides a high resistance to chloride ion pitting and crevice corrosion.

A-286 is easily cold worked and forged and can be machined and welded in an annealed condition. This grade is relatively easy to form and machine and is commonly used in hot and cold heading applications.

In conclusion, A-286 (0Cr15Ni25MoTiAlVB) stainless steel is a precipitation-hardened stainless steel that provides a combination of high strength, good corrosion resistance, and thermal stability. The alloy also has a high chromium content that gives it excellent corrosion resistance and hardening capability. A-286 stainless steel is used in industrial applications such as turbine blades, fasteners, valves, and shafts. This grade is easily cold worked and forged and can be machined and welded in an annealed condition, making it suitable for a wide range of applications.

A-286 stainless steel, also known as 0Cr15Ni25MoTiAlVB, is a precipitation hardened stainless steel with excellent creep strength and is widely used in high temperature and high pressure applications. It is a fully austenitic alloy designed for use at temperatures up to 700°C and offers high strength in the temperature range of 650 to 1200°C.

A-286 stainless steel contains 15.0% chromium, 25.0% nickel, 2.5% molybdenum, 1.2% titanium, 0.35% aluminum, 0.07% vanadium and a balance of iron. This combination of elements gives the alloy great strength, excellent corrosion resistance and excellent resistance to oxidation up to 1500°C. The corrosion resistance is similar to that of grade 304 stainless steel, but with better high temperature properties. The alloy is age hardenable which significantly increases its strength, making it a popular choice for applications that require high strength at high temperature, such as turbine blades, fasteners, and impellers.

A-286 stainless steel has good fabrication properties and can be formed, welded and machined. It can be welded using conventional welding processes such as gas tungsten arc welding and gas metal arc welding. However, it should be noted that welding, especially of thick components, should be avoided due to its high propensity to form hot cracking.

The alloy typically has a hardness of 40-45 HRC and a minimum yield strength of 430 MPa, making it an ideal choice for components subject to high stress, such as fasteners and valve parts. Its excellent creep strength makes it suitable for components used in rocket motors and aircraft engines.

In summary, A-286 stainless steel 0Cr15Ni25MoTiAlVB is a precipitation hardened stainless steel that offers excellent high temperature strength and creep resistance, as well as good corrosion and oxidation resistance. It is a popular choice for applications that require high strength at high temperatures, and is widely used in aircraft and automotive components, fasteners and valve parts.
