Technical features
(1) Cr Ni Mo or Cr Ni Medium Carbon Low Alloy Steel Microalloyed with V, Ti or Nb is used to improve the purity and refine the grain through vacuum smelting + electroslag remelting, so as to improve the process properties such as toughness and formability, and achieve high bulletproof performance through heat treatment

(2) The martensitic lath bundle size of the steel was refined from tens of microns to several micrometers and submicrons by controlled rolling and cooling; The ultra-fine grain structure can greatly improve the strength and plasticity of the steel, so as to improve the bulletproof performance

technical level
(1) Thickness specification: 2mm ~ 20mm;
