ASTM A572 grade 50 carbon steel coil is a high-strength low-alloy structural steel with a yield strength of ≥345MPa (50ksi), a tensile strength of 450-600MPa, and an elongation of ≥18%. It is produced by hot rolling process and has a thickness range of 1.5-25.4mm.
ASTM A572 steel coil is a popular grade of high-strength low-alloy (HSLA) steel that is typically used in structural applications. A572 steel contains chemical alloys that enhance the material’s hardness and ability to bear weight. There are five different grades of A572 steel coil: Grade 42, Grade 50, Grade 55, Grade 60 and Grade 65.
A572 grades are divided into: 42, 50, 60, 65. The steel plate is light in weight, but has good strength, ductility and workability, making it an ideal choice for structural applications. These characteristics make the A572 relatively simple to shape into different structures, while maintaining the ability to withstand large stresses and loads.
