Chemical Composition: The chemical composition of A874/A874M-98(2014) steel grade refers to the elements present and their relative amounts in the steel. It determines the steel’s properties, such as its strength, ductility, and corrosion resistance. By understanding the chemical composition, engineers and metallurgists can tailor the steel’s properties to suit specific applications.
Mechanical Properties: The mechanical properties of A874/A874M-98(2014) steel grade refer to its physical properties, such as strength, hardness, toughness, and elasticity. These properties are derived from the steel’s microstructure, which is influenced by factors like chemical composition, heat treatment, and mechanical processing. Understanding the mechanical properties helps in selecting the appropriate grade of steel for different applications and predicting its behavior under various loading conditions.
Standard Number: A874/A874M-98(2014) is a standard specification issued by ASTM International, a globally recognized organization that develops and publishes technical standards for various materials, products, systems, and services. This standard specifically pertains to the requirements for high-strength low-alloy structural steel plates produced by thermo-mechanical controlled process (TMCP). The standard provides guidelines and test methods for the chemical composition, mechanical properties, and dimensional tolerances of the steel plates.
Corresponding: The term “corresponding” in this context refers to the match or association between the specifications or requirements of a particular steel grade and the standard to which it belongs. In the case of A874/A874M-98(2014) steel grade, the term “corresponding” implies that this steel grade complies with the specifications outlined in the A874/A874M-98(2014) standard. The corresponding standard ensures that the steel grade being referred to meets the necessary criteria for its intended use.
