Tips for selecting alloy steel balls
In this mixed market,a variety of products,whether counterfeit or genuine,are not uncommon.Whether the quality is guaranteed is another matter.So how should we judge the quality?The quality of steel shot alloy directly determines its use,so how should we purchase it?
Alloy steel shot,also known as cast steel shot,is available in high carbon steel shot(high carbon cast steel shot)and low carbon steel shot(low carbon cast steel shot is also commonly referred to as bainitic steel shot).After melting at℃,metal abrasives are obtained by centrifugal atomization granulation or water impact atomization granulation,drying,sieving,and packaging.
For the types of steel balls,the production materials and equipment selected for different alloy steel balls are different.Currently,waterless production technology is mainly used,which can effectively solve defects such as casting pores and slag inclusions,greatly improving product quality and meeting quenching requirements.We also remind our friends here that when adding new alloy steel balls,we must remember the principle of adding a small amount of steel.
The chemical composition and carbon content of the product should be moderate.Silicon and manganese can improve the strength and hardness of alloy steel balls,and should be as high as possible.Sulfur and phosphorus are harmful elements that can easily make them brittle and cause premature cracking,so they should be minimized as much as possible.
2.Identification must be based on ingredients and specifications,as products of different specifications can achieve better results.Too soft alloy steel shot will slow down the cleaning speed and reduce work efficiency.During shot peening,if it is too soft,appropriate residual stress will not be generated.
For low hardness products,it is not possible to compensate for the force by increasing the impact time.If the hardness is too high,it will result in poor appearance,increase the possibility of steel shot breakage,consume too much,wear more equipment,and increase equipment maintenance costs.Therefore,appropriate hardness is also crucial.
