Abstract: An article of manufacture formed of an alloy having the following weight percent composition is described. Carbon 0.25 max. Manganese ?14-20? Silicon up to 2.0 Phosphorus 0.05 max. Sulfur ?0.5 max. Chromium ?12-22? Nickel ?3.5 max. Molybdenum 0.5-4?? Copper ?2.0 max. Nitrogen 0.2-0.8 Boron 0.06 max. The balance of the alloy is iron and the usual, inevitable impurities found in commercial grades of stainless steel alloys. Optionally, the alloy may contain niobium, titanium, vanadium, zirconium, hafnium, and tungsten in a combined amount of up to about 0.5%. An intermediate form of the article is armor plate made from the alloy. In accordance with another aspect of the present invention, the plate is shaped to form an armor part that is attached to a larger structure to provide resistance to an explosion fragments or a ballistic projectile.
