AISI S7
AISI S7 steel is a shock-resistant tool steel that is classified under the American Iron and Steel Institute (AISI) designation system. It is known for its high impact toughness and excellent wear resistance, making it suitable for applications that require both strength and impact resistance.
The chemical composition of AISI S7 steel typically includes elements such as carbon (C), chromium (Cr), molybdenum (Mo), silicon (Si), and vanadium (V). The specific composition may vary depending on the manufacturer or specifications.
One of the notable features of AISI S7 steel is its ability to retain its hardness even at elevated temperatures, which makes it suitable for use in high-temperature applications. It can be hardened by heat treatment processes such as quenching and tempering, which enhance its hardness, strength, and wear resistance.
