1050 steel structure is a medium carbon, medium tensile steel with good strength, toughness and wear resistance.
1050 steel structure is a versatile medium carbon engineering steel that can be through hardened to a little over 2.5" (63mm), as well as being flame or induction hardened to Rc61. The steel can be readily welded and machined providing correct procedures are followed.

1050 steel structure MACHINABILITY
Machinability of C1050 is good providing the full annealing cycle described above is used, A coarse lamellar pearlite to coarse spheroidite microstructure gives optimum machinability in C1050.
1050 steel structure WELDABILITY
This grade is readily welded with the correct procedure. Welding in the through hardened or flame or induction hardened conditions is not recommended.
