4.Heat treatment of 1050 Carbon Steel

Acc. to your request, Standard steel bar(sawing) , non standard steel bar(sawing) or Mill deliver condition,without 

sawing or cutting,Conventional or ESR, hot rolled or forged, black surface or milling,

Hardness: annealed to HB≤207.

1.EAF: Electric Furnace+LF+VD(Optional)

5.Characteristic of 1050 Carbon Steel

(1) Higher strength in a high-quality carbon steel.

(3) due to poor hardenability, general normalized state, high mechanical performance requirements, the use of

quenched and tempered.

(4) Moderate in cold plastic deformation, the machinability by annealing and normalizing is better than quenched 

and tempered.

6.Application of 1050 Carbon Steel

(2) For the machining parts and spring pieces with little dynamic and impact loads, such as forging gear, rod, roll axis,

friction plate, agricultural earthmoving plowshare, heave-duty spindles etc.
