Honest Horse Martensite And Bainite Steel Shot
Bainite shot has the ideal microstructure for peening and blast cleaning.There's another reason why Bainite shot is tougher and more fracture resistant than Martensite shot. Seen through a microscope. Bainite appears acicular (rods) and featherlike, forming an interwoven lattice type microstructure. In addition to providing excellent resistance to stress and quench cracking, the Bainite microstructure enables the shot to wear at a controlled rate, maintaining its overall shape and uniformity its entire life.
These characteristics are especially significant to customers with exacting requirements, such as those in the aerospace industry. Unlike Martensite, Bainite can not break up at random and form sharp edges Sharp edges can impart surface imperfections which later cause the failure of critical parts. And Bainite never leaves a residue prone to rusting on non-ferrous parts, another problem often encountered by Martensite customers.
