AISI 4140 42CrMo4 1.7225 SCM440 - Waldun Steel

AISI 4140 is defined as a low alloy steel which has 1% Cr-Mo as strengthening alloy elements.Compared with AISI 4130, it has a higher carbon content with good balance of strength, toughness ,abrasion and impact resistance and heat treatment capabilities,but poor in weldability characteristics.AISI 4140 is generally supplied in quenched and tempered condition with hardness 28-32HRC. AISI 4140 Alloy SteelThe mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT.

the mechanical properties of the 34CrNiMo6 steel are studied under steady-state conditions and impact conditions. The strength decreases while the elongation after breakage increases with the increasing tempering temperature. The impact-absorbing energy at 20 °C and 40 °C increases with the increasing tempering temperature.

EN24T Steel Properties

EN24T Steel Properties. EN24T / 817m40. EN24 is usually supplied in the T condition with a tensile strength of 850/1000 N/mm 2. EN24T steel is a popular grade of through-hardening alloy steel due to its excellent machinability in the "T" condition. EN24T is used in components such as gears, shafts, studs and bolts, its hardness is in the range EN24T, EN24 SteelEN24T is most suitable for the manufacture of parts such as heavy-duty axles and shafts, gears, bolts and studs. EN24T can be further surface-hardened typically to 58-60 HRC by induction or nitride processes, producing components with enhanced wear resistance. In addition to the above, EN24T is capable of retaining good impact values at low

  • AbstractIntroductionMaterials and MethodsResults and DiscussionConclusionsData AvailabilityConflicts of InterestAcknowledgmentsThe effect of rare earth Ce on mechanical properties is studied by investigating the precipitates evolution during heat treatment of 34CrNiMo6 steel. Five different rare earth Ce contents are carried out with the same holding time 3hours. Then, the mechanical properties of 34CrNiMo6 steel are obtained under steady state conditions and impact conditions, respectively. The strength decreases while the elongation after breakage increases with the rare earth Ce content increasing.
