Product Features Of Steel Shot

- Sep 15, 2017 -

Steel shots are a kind of spherical particles made of special heat treatment by special heat treatment. First, the high quality steel blocks are melted, and then the molten steel is granulated by high pressure water injection. The pellets are reheated to purify the homogenization, and then then quenching. 

The following describes the product characteristics of steel balls:

   The pellets after quenching are dried and reheated and tempered in the furnace to achieve the desired hardness. The tempered steel balls are sorted by mechanical screens to different grades of SAE-compliant products for shot blasting equipment. 

The Moderate hardness, toughness, impact resistance, long life, up to 2000-2900 times, good rebound, clean up fast, low consumption, not broken, clean up fast, technical effect is good. The surface of the metal surface cleanliness up to GB / T8923-1989; surface roughness Rz = 10-150μm, hard metal processing, hardness can be increased to hrc57 ~ 62. Their toughness is better, the service life is several times than cast iron shot, steel shots are widely used. 

Steel shot of high quality alloy steel sand, high density, less defects, narrow particle size distribution, the heat treatment after the microstructure is good, excellent mechanical properties, steel ball toughness and resistance to crushing, anti-fatigue performance greatly improved reuse rate, Low consumption, significant economic benefits. Steel shots can be widely used in steel structure before painting the shot peening machine parts surface strengthening, surface finishing and other operations.
