Alloy Steel composition and price per kg in India

Low Alloy Steel allowable stress at a glance with ASTM standard specification and equivalent grades.

Alloy Steel propertiesdiffer from alloy to alloy. It is a broad term and there are thousands of alloy steel materials available and are used for different purposes. There are differentAlloy Steel gradesthat are derived through the different compositions of the different alloys. These alloys are basically steel with alloying material between 1% to 50% of the total composition in weight. The alloys could be divided into two subgroups. The high alloys and the low alloy steel. The low alloy steel has lower amounts of alloying material and high alloy steel has higher amounts of alloying material. The definition of what quantity is not definitive yet. TheAlloy Steel applicationsrange over a variety of industrial, domestic and commercial use cases. From household and kitchen accessories to larger industrial machine parts, the materials are used for their strength and cost effective nature.

Each alloy is different and some of them have excellent and unique properties that are applied in unique applications. TheAlloy Steel advantagesare that they could be used in place of high cost materials with the addition of elements and tweaking the chemical composition a little bit. So the cost is reduced to larger extents. TheAlloy and its typesare based on the composition and the cost is per kg. TheAlloy Steel price per kgis much lower than the prices of other metal alloys or pure metals like titanium and copper. TheAlloy Steel supplierssell these products in combination with other metal products. AS are one of the most sold metallic products in the world. The AS composition can include a host of other elements such as manganese, molybdenum, chromium, nickel, silicon, nitrogen and a lot of others depending on the material in question.
