Flame Cutting Textured Steel Armor

Abstract

Undesirable metallurgical transformations and high tensile residual stresses in the region of flame cut edges have necessitated the use of high preheat temperatures, often in excess of 550, for the flame cutting of high strength steels. In addition, grinding is generally required for all thermal cur surfaces not subjected to welding, if cut surfaces are on a part that is dynamically loaded. The combination of hig preheat temperatures and secondary grinding requirements translates to high cutting costs for high hardenability armor steels. The purpose of the work presented here is to establish oxy-fuel cutting guidelines for an ultrahigh hardenability armor steel, textured steel. Keywords: Crack propagation; transverse edge cracking; hydrogen induced cracking;
