Stainless STEEL 40X13 (4Х13) pertained to the category of corrosion-resistant high-temperature alloy of the martensitic class. Significant chromium And carbon Content results in high hardness, wear resistance, the elasticity of the sheet And Tape to mark 40X13 material. Chromium gives resistance to corrosive destruction. It forms on the surface of semi-durable protective oxide film that protects the product from corrosion, and additional alloying ensures the stability of working characteristics of raw materials and increases its resistance. High iron content significantly reduces the alloy. The disadvantage is poor weldability.
