MALLTECH is offering several new grades of alloy steel characterized by superior mechanical properties, good processing characteristics and relatively low cost. These grades were developed as a result of many years of research into the effects of various groups of alloying elements on the structure and properties of alfa- and gamma- iron based steels subjected to various types of heat and chemical treatment. From this research came an alloying system based on a particular combination of three alloying elements, {Si + Cu} /V; it is universal in its applicability to production of various classes of steels, from low carbon high ductility to high carbon tool steel, stainless and martensite aging. *SCV10 -high-ductility steel
SCV25 -case hardening steel * SCV40 -direct hardening, nitriding steel * SCV50 -die, spring nitriding steel * SCV60 -tool steel * SCV10Cr16 -stainless, high-ductility steel 8 SCV40Cr16 -stainless, direct hardening steel * SCV60Cr16 -stainless, tool steel. SCV steel has good hardenability and machinability as well as the following characteristics:-high strength when subjected to hardening over the entire tempering range (150-700º C);low predisposition to type 2 temper brittleness in the critical tempering and nitriding zone (480-540ºC); capability for surface strengthening of heavy-duty components by low-distortion, low-temperature nitriding to depth of 0.8 mm, without jeopardizing the integral strength of the components; wear resistance of hardened and nitrided samples comparable to that of ball bearing steels hardened to 62-64 HRC; fatigue strength of hardened and nitrided samples comparable to that of high-alloy structural steels that contain high concentrations of elements such as Mo, Ni and Co. contact fatigue of hardened and nitrided samples comparable to that of the best carburizing and nitrocarburizing alternatives. Nomenclature and wide technological versatility combined with a superior complex of mechanical and operational characteristics and moderate cost of SCV steels provide designers with greater freedom in implementation of engineering ideas, both today and in the future, and help to ensure high accuracy, reliability and durability of machines being designed
