When in use, the strength requirements for pig iron castings are different according to the different industries used, so how to increase the strength of pig iron castings?

1. When making pig iron castings, a small amount of carbon can be added to the raw materials. The content of carbon is closely related to its strength. For ordinary pig iron castings, its carbon content is between 2.6% and 3.6%.

In addition, it also contains some silicon, the content of which is between 1.2% and 33%.

Of course, when determining the wall thickness of pig iron castings, manganese should also be added appropriately.

2. Use alloying method to improve the tensile strength of gray iron castings. We know that the strength of alloy is generally relatively high, but molten iron must be properly inoculated when in use.
