Yes, ASTM A514 and T1 steel are essentially the same material in practice. T1 is a proprietary trade name (originally from U.S. Steel, now owned by ArcelorMittal) for a high-strength low-alloy (HSLA) steel that meets the specifications of ASTM A514/A514M. Specific T1 types often correspond to A514 grades: for example, T1 Type A aligns with A514 Grade B, and T1 Type B with A514 Grade H. Both are quenched and tempered steels with high yield strength (over 100 ksi/690 MPa), used in structural and heavy equipment applications. As a leading manufacturer and exporter, Gangsteel produces high-quality ASTM A514/A514M steel plate equivalent to T1 specifications, offering grades like astm a514 grade b for versatile use.
While A514 and T1 refer to the same type of steel, the distinction lies in naming: A514 is the ASTM standard designation, while T1 is a trademarked name. They share identical chemical compositions and mechanical properties in corresponding grades. Below is a comparison table for clarity:
