Chemical Composition of Austenitic Precipitation Hardening Stainless Steel 0Cr15Ni25MoTiAlVB(A-286)

A-286 stainless steel is an iron-based steel alloy that has been developed to provide a range of hardening and precipitation hardening properties. A-286 was designed to be an economical alternative to more expensive high-end alloys such as Incoloy and Inconel. The most common applications for A-286 steel are for high temperature fasteners such as bolts, screws, and studs. The alloy is also used for other industrial applications that require high temperature exposure without excessive deformation. The main chemical components of A-286 stainless steel are 0Cr15Ni25MoTiAlVB.

Chromium (0Cr) is the primary component in A-286 stainless steel, as it is found in all common stainless steels. Chromium is known for being highly corrosion resistant, which is why it is a common component of stainless steels. The addition of chromium to A-286 alloy creates added resistance to corrosion when exposed to elements such as acids, water, and oxygen.

Nickel (15Ni) is another component of A-286 stainless steel, and is added to provide improved toughness and strength at elevated temperatures. Nickel also contributes additional corrosion resistance, making A-286 stainless steel even more resistant to corrosion when exposed to elements such as acids, water, and oxygen.

Molybdenum (25Mo) is a common component of stainless steels, and is added to A-286 stainless steel for increased strength and toughness at elevated temperatures. It also contributes to the increase in corrosion resistance, making the alloy even more resistant to elements such as acids, water, and oxygen.

Titanium (Ti) is a component of A-286 stainless steel for strength and added corrosion resistance. Titanium has the ability to form a protective oxide film that helps to prevent corrosion when exposed to elements such as acids, water, and oxygen.

Aluminum (Al) improves the strength and toughness of A-286 stainless steel. It also helps to increase the rigidity of the alloy, which is important when under extreme temperatures and in high-strength applications.

Vanadium (V) is a component of A-286 stainless steel for increased strength and toughness. Vanadium helps A-286 stainless steel retain its hardness throughout its lifetime, even when exposed to extreme temperatures.

Boron (B) is a component of A-286 stainless steel for increased strength and stiffness. It also helps to improve cold formability, which is important when machining the alloy.

A-286 stainless steel is a high-end iron-based alloy that is designed to provide a range of hardening and precipitation hardening properties. It is commonly used for high temperature fasteners such as bolts, screws, and studs as well as other industrial applications that require high temperature exposure without excessive deformation. The main chemical components of A-286 stainless steel are 0Cr15Ni25MoTiAlVB. Chromium, nickel, molybdenum, titanium, aluminum, vanadium, and boron are all components of A-286 stainless steel, and when combined they give the alloy added strength and corrosion resistance, making it suitable for high temperature applications.

Chemical composition of 0Cr15Ni25MoTiAlVB (A-286) high-temperature and precipitation-hardening stainless steel

0Cr15Ni25MoTiAlVB (A-286) high-temperature and precipitation-hardening stainless steel is a highly alloyed precipitation hardening stainless steel used mainly in the aerospace industry. Its high strength and creep resistance make it an excellent choice for components that are subjected to a variety of loads and temperatures. Its chemical composition comprises of iron (75-80%), chromium (14-18%), nickel (24-30%), titanium (0.5-1.5%), molybdenum (1.0-2.0%), aluminum (0.2-2.0%), vanadium (0.2-0.5%) and boron (< 0.03%). Other trace elements such as copper, silicon, and niobium may also be present in different amounts.

The primary elements that contribute to 0Cr15Ni25MoTiAlVB (A-286)’s excellent mechanical properties are chromium and molybdenum. Chromium, which is the primary alloying element for stainless steel, lends to the materials excellent corrosion resistance, as well as its excellent mechanical properties. Molybdenum, a common strengthening element, increases the strength and creep resistance of the stainless steel at elevated temperatures. The addition of nickel improves corrosion resistance and strength at room temperature, while the addition of titanium and aluminum to the alloy further increases corrosion resistance and weldability. Vanadium, on the other hand, improves the grain structure by refining and adding strength to the material.

The addition of boron to 0Cr15Ni25MoTiAlVB (A-286) stainless steel further enhances the properties of the material, improving tensile and yield strength, as well as hardness at both ambient and high temperatures. The various elements and their contents all contribute to a product that is strong, highly corrosion-resistant, and also able to perform at high temperatures. This combination of properties makes this stainless steel an excellent choice in many industries, particularly aerospace.
