42CrMo4 40CrNiMo Carbon Alloy Forging

TORICH 420 304 40CrNiMo Annealing and Tempering Stainless Carbon Alloy Forging

1. Brief introduction:

What is the forging: 

Forging is a processing process. A forging is an object in which a metal is subjected to pressure to shape the required shape or suitable compression force through plastic deformation. This force is typically achieved through the use of a hammer or pressure. The forging process creates a fine grain structure and improves the physical properties of the metal. In the actual use of parts, a correct design can make the particles flow in the direction of the main pressure.

Forgings need to be consistent in each piece, without any porosity, inclusions or other defects. The components produced by this method have a high ratio of strength to weight.

The advantages of forgings are stretchable length; shrinkable length and stretchable cross-section; changeable length and changeable cross-section.

Details:

Forgings need to be consistent in each piece, without any porosity, inclusions or other defects. The components produced by this method have a high ratio of strength to weight. These elements are commonly used in aircraft structures.

The advantages of forgings include stretchable length and shrinkable cross-section; shrinkable length and stretchable cross-section; changeable length and changeable cross-section. The types of forgings are: free forging/hand forging, hot die forging/precision forging, upsetting, roll forging and die forging.

QUALITY CONTROL:

1. Incoming Raw Material Inspection

2. Raw Material Segregation to avoid steel grade mix-up

3. Heating and Hammering End for Cold Drawing

4. Cold Drawing and Cold Rolling, on line inspection

5. Heat Treatment, +A, +SRA, +LC, +N, Q+T

6. Straightening-Cutting to specified length-Finished Measuring Inspection

7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc

8. Packing and Stocking.
