Which is the best between Alloy steel grits and Steel grits

- Jan 25, 2018 -

Frandcom industrial limited offers varous types of steel grits from China,like steel grits and alloy steel grits. But among those types, which one is the best one? And any different between them? Let's check and see.


 Firstly the material is different
We usually at the time of production, alloy steel shot of raw material is made of bearing steel scraps, and ordinary steel shot, steel grit selection is common steel scrap.


Second, the heat treatment process and equipment are both different
Alloy steel grit annealing process is adopted in accordance with the requirements of the annealing furnace, and isothermal quenching heating using box-type furnace, cooling by salt bath isothermal quenching, and the common steel shot, steel grit adopts roller tempering furnace, heat treatment and for air cooling, the craft that make different determines the quality of products in the process of using.


Third different chemical composition
1, alloy steel grit chemical elements including carbon, silicon, manganese, phosphine, sulfur, chromium, nickel, cobalt and other elements.
2, while the chemical composition of ordinary steel shot which only carbon, silicon, manganese, phosphine, sulfur and other elements.
So in order to ensure the quality of the use of alloy steel grit, we product when the choose and buy must distinguish what kind of product is alloy what is ordinary, the choose and buy high quality products.


Forth appreance is different Normal steel grit has sepherical surface,but Alloy steel grit has angular surface.
