DIN 1.6657 14NiCrMo13-4 16NCD13 832M13 EN36C Specifications 14NiCrMo13-4 datasheet, 1.6657 Chemical,14NiCrMo13-4 properties ssteelmaking, ESR, blooming, hot forging & rolling, heat treatment, straightened, ultrasonic test, cold working, machined. We also possess advanced precision machining equipments for further processing. Material specification - DIN EN 10084 (1998), DIN 17210 (1986)
MATERIAL CATEGORY: Carburizing structural steel
Proven performance in long-term service.Extensive database of long term, high temperature test results.High room and elevated temperature strength.Good creep.High notch tolerance.
Thermal expansion coefficients compatible with low alloy steel turbine casing materials.Lower design and operating risks
Simplified design for bolting configuration compared with martensitic steels or high nickel alloys.Alloy structural steel is provided with higher yield strength, tensile strength, endurance strength, yield ratio (about 0.85 generally ) enough plasticity and toughness.
The concentration of alloy element of this kind of steel is quite high, mainly are corrosion resistant steel, heat resistant steel, wear resistant steel, and other special steels of physical and chemical properties. Alloy structural steel has preferable mechanical property than that of carbon structural steel, high performance of heat treatment especially.The alloy is usually produced by EAF /VD /LF followed by electroslag refining (ESR) if necessary for special purpose.Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.Bars are usually supplied bright in the annealed condition, or bright annealing specially.
Final heat treatment - heat treatment / QT
