The mechanical properties of industrially produced perforated steel plates are obtained by hardening and low-temperature tempering to produce a martensitic microstructure. Another morphological type of steel microstructure that allows for ultra-high strength and. at the same time. a level of ductility that qualifies it for use in armour is nanobainite. https://countryscenesaddleryandpetsuppliers.shop/product-category/saddle-protector/
