High Quality Steel grades Comparison Table
High quality steel, also known as “structural grade steel”, is a type of steel that has been developed and specified to meet the demands of modern applications, with properties that ensure it can be used in the physically demanding structures and applications of industrial, commercial and construction projects.
The used grades of high quality steel range from mild carbon steels to specialty alloys with enhanced strength, corrosion resistance and other properties. Alloy and carbon steels, as well as some specialty alloys, are available from both domestic (USA) and import sources. When selecting a grade of high quality steel, it’s important to match the grade of steel with the intended application and use.
The table below provides a comparison of the commonly used grades of high quality steel in domestic and imported sources.
