Carbon Grades
1018 (1.0038 / S235JR)
Unalloyed structural steel with good weldability. It’s uses can be for structural, pipes, and other profiles.
A36
Unalloyed structural steel, comparable to 1018, but with a slightly higher carbon content. It is mainly used for welded structures.
1020 (1.0402 / C22)
Unalloyed structural steel with good weldability. It is comparable to the 1018, but with a slightly higher carbon content. It is used for steel construction elements, profiles, pipes, and other profiles.
1045 (1.0503 / C45) (1.1201 / C45R) (1.1191 / C45E) (1.1730 / C45U)
Unalloyed structural steel with a medium carbon content for a higher hardness after hardening. The 1045 is used in general machine and vehicle construction. But it is also used for mounting plates, hand tools, and agricultural tools.
1060 (1.0601 / C60) (1.1221 / C60E) (1.1223 / C60R) (1.1740 / C60U)
The 1060 is an unalloyed structural steel with a higher carbon content than the 1045. This gives it a slightly higher hardness after hardening. On the other hand, it also has a lower toughness. Like the 1045, the 1060 is used for general applications in machine and vehicle construction. It is also suitable for hand tools, chisels, and agricultural tools.
ASTM A572 Grade 50
Unalloyed structural steel.
Rounds, Squares, Hex, Flats
Turned, Ground, & Polished
The 1060 is an unalloyed structural steel with a higher carbon content than the 1045. This gives it a slightly higher hardness after hardening. On the other hand, it also has a lower toughness. Like the 1045, the 1060 is used for general applications in machine and vehicle construction. It is also suitable for hand tools, chisels, and agricultural tools.
