"4118/18crmo4/ 20CrMo/ DIN1.7218 Forged steel" is listed under  Steel StructuresCategory

4118/18crmo4/ 20CrMo/ DIN1.7218 structure steel 20 crmo - introductionBrand: 20 crmoStandard: GB/T 3077-1988Corresponding standard, JIS G4053:2003ASTM A29M: 2005Also thou ISO 683-683Unified digital code: A3020220 crmo - performance is introducedSecond-ranking characteristics and scope of application:High hardenability, no temper brittleness, weldability is quite good, the formation of cold cracking tendency is very small, good machinability and cold strain and plastic. Generally in the quenched and tempered or carburizing and quenching condition, used in the manufacture of the corrosive medium and working temperature below 250 & 176C, containing hydrogen nitrogen mixture medium work in high pressure pipe and all kinds of fasteners, more senior carburized parts, such as gear, shaft, etc.Low chemical composition:Carbon C: 0.17 ~ 0.24Si Si: 0.17 ~ 0.37Manganese Mn: 0.40 ~ 0.70S: sulfur residual content of 0.035 or less are allowedP P: residual content of 0.035 or less are allowedChromium (Cr: 0.80 ~ 1.10Ni Ni: residual content of 0.030 or less are allowedCopper Cu: residual content of 0.030 or less are allowedMo Mo: 0.15 ~ 0.25Low mechanical properties:Tensile strength of sigma (MPa) : b 885 or higher (90)Yield strength sigma (MPa) : s 685 or (70)Elongation is the delta ( Percent) : 12 or higherReduction of bits ( Percent) : 50 or moreImpact energy Akv (J) : p. 78Impact toughness value of alpha kv (J/cm2) : 98 (10) or higherHardness: hb 197 or lessSample size: blank sample size is 15 mm20 crmo - useGear, fasteners, flanges, nuts, etc The higher hardenability, non-temper brittleness, very good weldability, forming a small tendency to cold cracking can be cutting and cold response of a good pyroplastic. Usually quenched and tempered or case hardening state used for the manufacture of non-corrosive media and working temperature below 250 , the medium containing a mixture of nitrogen and hydrogen in the work of the high-pressure pipe and various fasteners, higher carburizing parts, such as gears, shafts and so on.
