Cast Steel Shot for S460/S550 with ISO9001 & SAE

Product Description

Cast Steel Shot for S460/S550 with ISO9001 & SAE

The molten metal is atomized and transformed into round particle and subsequently quenched and tempered in a heat treating process to obtain a product of uniform hardness and microstructure, screened by size according to SAE Standard specification.

1. Steel shot picture 




Steel Shot is manufactured by melting selected scrap in electric induction furnace.

The chemical composition of molten metal is analyzed and strictly controlled by spectrometer to obtain SAE Standard specification.

3. Steel Shot Production Procedure

1 Smelting ( steel scrap + alloy)
 
2 Forming
 
3 Drying
 
4 Screening (separate the SAE shot size from the oversized shot particles used for grit production)
 
5 Selection(remove irregular shaped shot)
 
6 Quenching (produce superior particle integrity with minimal stress cracks)
 
7 Tempering
 
8 Screening
 
9 Packaging (25 KGS per one small pp bag)


 

4. Steel Shot Applications

shot blasting 

Fettling

cleaning the casting sand and burnt -on sand of the casting to make the surface get good cleanliness and required roughness, so that can be benefit to the subsequent processing and coating.

Steel plate surface preparation

Cleaning the oxide skin, rust and other impurity by shot Blasting, then using the vacuum cleaner or the purified compressed to clean up the steel products surface.
