This type of stainless steel material is probably the most widely used due to its wide range of uses and it’s relatively low cost compared to other types of stainless steel. Balls made from this material offer many of the same characteristics as some of the other versions of stainless steel including good corrosion resistance, mechanical hardness and their structure ensures they are resistant to pure water, steam, oil and gas as well as many others.
