ASTM A633 Gr C HSLA steel plate size

There are four grades,designed Grades A, C, D, E under ASTM A633 high-strength low alloy structural (HSLA) steel standard. A633 Gr C HSLA steel plate is suitable for service at low ambient temperatures of -50℉[-45℃] and higher where notch toughness better that expected in as-rolled material of a comparable strength level is desired.
