How to choose alloy steel shot

In this mixed market, all kinds of products, whether fake or genuine, are not uncommon. Whether the quality is guaranteed or not is another matter. So how should we judge the quality? The quality of the alloy steel shot directly determines the quality. Its use, the quality is not sloppy, so how should we buy it? Liaoning steel wire cut shot

Alloy steel shots are also called cast steel shots. There are high-carbon steel shots (high-carbon cast steel shots) and low-carbon steel shots (low-carbon cast steel shots are also commonly known as bainitic steel shots). After smelting at ℃, the metal abrasive is obtained after centrifugal atomization granulation or water impact atomization granulation, drying, sieving, packaging, etc.

Speaking of the types of steel shots, the selected production raw materials and production equipment for different alloy steel shots are different. At present, the anhydrous production process is mainly used, which can effectively solve the casting defects such as pores and slag inclusions, and greatly improve the product The quality also meets the quenching requirements. We also remind our friends here that when adding new alloy steel shots, we must remember the principle of adding a small amount of steel.

1. The chemical composition and carbon content of the product concerned should be moderate. Silicon and manganese can enhance the strength and hardness of alloy steel shots, and should be as high as possible. Sulfur and phosphorus are harmful elements, which are easy to cause brittleness and cause premature rupture, which should be as low as possible.

2. It must be identified in terms of ingredients and specifications. Products with different specifications can achieve better results. Too soft alloy steel shot will slow down the liquidation speed and reduce work efficiency. During shot peening, if it is too soft, it will not produce suitable residual stress. For products with low hardness, the force cannot be compensated by increasing the impact time. If the hardness is too high, it will produce undesirable appearance, increase the probability of crushing of alloy steel shots, make the consumption too high, and wear more equipment, increase equipment maintenance costs, so the appropriate hardness is also very important.
