Direct Sale GB 9SiCr/ 9XC Carbon Tool Steel Round Bar
1: 9SiCr steel introduction
9SiCr steel is a high-carbon alloy tool steel, good toughness, good tempering stability, heat treatment deformation is small. Its surface residual carbon content of 0.6%-0.7% decarburization layer, due to the reduction of carbide makes the surface layer of superheat sensitivity increases. After quenching by normal heating surface hardness can still reach 60-62HRC, but its bending strength is reduced by 40% -50%.

The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

| Application | 9SiCr steel is suitable for the manufacture of tools with complex shapes, small deformation, high wear resistance and low-speed cutting, such as drills, threading tools, reamers, plate teeth, taps, thread rolling plates and wire rollers. In addition, it is also widely used in the manufacture of larger size, more complex shape and higher precision plastic mold. In the mold manufacturing, 9SiCr steel is commonly used in the production of punching material thickness ≥ 3mm blanking die in the shape of complex convex die concave die inserts | |
6: Heat Treatment
Annealing Temperature: Generally annealed at 750-780ºC.
Holding time: The holding time depends on the size of the specific workpiece, and is maintained for sufficient time to ensure a uniform internal structure.
Slow cooling: After annealing, slowly cool to room temperature with the furnace.
Quenching: Heating to 810-830°C followed by oil or air cooling.
Tempering: After quenching, tempering treatment is carried out, and the tempering temperature can generally be 150-200°C or higher (adjusted as required) to ensure that the final hardness is within the appropriate range to meet the requirements of use.
7: Delivery condition
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
