The analysis of the chemical composition of A696-90a(2012) steel grade reveals its versatility in various applications. A696-90a(2012) steel grade is predominantly composed of iron (Fe), which is the base element of most steels. It also contains other elements that contribute to its mechanical properties and enhance its performance.
One of the key elements found in A696-90a(2012) steel grade is carbon (C). Carbon imparts strength and hardness to the steel, making it suitable for applications that require toughness and wear resistance. The carbon content in A696-90a(2012) steel grade ranges from 0.20% to 0.23%.
Another important element in A696-90a(2012) steel grade is manganese (Mn). Manganese enhances the hardenability and tensile strength of the steel. The manganese content in A696-90a(2012) steel grade ranges from 0.90% to 1.30%.
Other alloying elements can be found in A696-90a(2012) steel grade, including silicon (Si), nickel (Ni), and chromium (Cr). Silicon improves the steel’s strength and resistance to oxidation. Nickel enhances the toughness and impact strength of the steel. Chromium improves corrosion resistance and hardenability. The silicon content in A696-90a(2012) steel grade ranges from 0.05% to 0.30%, the nickel content ranges from 1.65% to 2.00%, and the chromium content ranges from 0.45% to 0.60%.
A696-90a(2012) steel grade also contains small amounts of other elements such as phosphorus (P), sulfur (S), and copper (Cu). Phosphorus and sulfur are impurity elements that can have detrimental effects on the steel’s toughness and ductility if present in high concentrations. Therefore, the phosphorus content in A696-90a(2012) steel grade is limited to a maximum of 0.025% and the sulfur content is limited to a maximum of 0.035%. Copper is added to improve corrosion resistance. The copper content in A696-90a(2012) steel grade ranges from 0.20% to 0.35%.
Overall, the chemical composition of A696-90a(2012) steel grade reveals a well-balanced combination of elements that provides it with excellent mechanical properties. Its versatility is evident in its ability to withstand high levels of stress, resist wear and corrosion, and maintain its strength and toughness in various environments. This makes A696-90a(2012) steel grade a suitable choice for a wide range of applications, including structural and mechanical components in industries such as construction, automotive, and manufacturing.
