GB 45 SPECIAL STEEL
1. Main application
(1) this steel is widely used in machinery manufacturing.
(2) For the manufacture of high strength requirements parts, such as gears, shafts, piston pin and the uneven force big machining parts, forgings, stampings and bolts, nuts, pipe joint.
2. Specification:
Round bar | Diameter(mm) | Length (mm) |

plate/sheet | Thickness(mm) | Width (mm) | Length (mm) |
20~600 | 600~2300 | 2000~5800 |
3. Delivery condition:
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≤215
4. Features:
(1) Higher strength in a high-quality carbon steel.
(2) Mechanical properties of this steel is very good.
(3) the hardeness of this steel could be 42~46HRC by quenching.
(4) due to poor hardenability, general normalized state, high mechanical performance requirements, the use of quenched and tempered.
(5) Moderate in cold plastic deformation, the machinability by annealing and normalizing is better than quenched and tempered.
