35CrMo Steel. 35CrMo steel is a Chinese alloy steel for engineering purpose, it has high durability and creep strength at high temperature, and low temperature impact toughness is good. The working temperature is up to 500 °C, the low temperature can be -100 °C, and has high static strength and high fatigue strength, good hardenability, no tendency to overheat, small quenching deformation
Analysis of Work Hardening Behavior in Ferrite in this study using duplex stainless steels, no comparison was made with different amounts of austenite-stabilizing elements. Therefore, it is unclear how changes in the volume fraction of martensite affect the work-hardening behavior. In this study, to clarify the contribution of the increase in martensite during tensile deformation in TRIP
A nanocrystalline layer was prepared on the surface of 34CrMo4 steel by time controlling shot peening (SP, i.e., 1, 5, 10, and 20 minutes). Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) analysis, and transmission electron microscope (TEM) were applied to analyze the surface, cross-sections, and grain size of the specimens before and after SP.

EN 1.7220 (34CrMo4) Chromium-Molybdenum Steel EN 1.7220 steel is an alloy steel formulated for primary forming into wrought products. 1.7220 is the EN numeric designation for this material. 34CrMo4 is the EN chemical designation. The properties of EN 1.7220 steel include five common variations. This page shows summary ranges across all of them.
Nov 13, 2019 · Tensile properties of experimental steel were observed to be highly sensitive to tempering time in the QPT heattreatment process. Variations in tensile properties including tensile strength (Rm), yield strength (R P0.2), elongation ( T) and reduction in area (R A) with varying tempering time are presented in table 3.
Effects of the Nanostructured Fe-V-Nb Modificators on the The nanostructured Fe-V-Nb master alloy was prepared in vacuum rapid quenching furnace and then was added in the steel melts as modificators before casting. Next, the effects of the nanostructured Fe-V-Nb modificators on the microstructure and mechanical properties of the steel were studied. The results show that the grain size of the steel has been effectively refined, which is mainly because
Finite Element Analysis of Tensile Behavior of Ductile In this article, a parametric finite element analysis using ANSYS-APDL (Ansys Parametric Design Langrage) is performed to predict the tensile behavior of the 34CrMo4 steel rectangular tensile
30 minutes-tempered samples. Figure 4 shows the tensile properties of as-quenched and 30 minutes-tempered sample of 440C martensitic stainless steel. It can be clearly seen that the UTS of the as-quenched sample was 517MPa and YS of 124Mpa. However, the UTS and YS of the as-tempered sample are 1044MPa and 368MPa, respectively.
Mechanical behavior of CrMo steel with tempered The tensile and low cycle fatigue properties of the multiphase steel are reported and compared with those of multiphase and tempered martensite microstructures obtained by forging. View Show abstract
Microstructures and Mechanical Properties of behavior is the major mechanism for the failure mode. In Figs. 8(c) and 8(d), although the dimple microstructures are observed, but the main mechanism are still splitting, and it is belong to brittle materials fracture mode, so it has a lower tensile strength. From failure mechanism, the brittle of thin plate specimen has high sensitivity (t
