20Cr2Ni4 Special steel china supplier OTAI Special Steel

OTAI SPECIAL STEEL is 20Cr2Ni4 tool steel stockholders and suppliers from china, more 16 years experience in steel round bar, flat bar, and plate supply. 20Cr2Ni4 steel is a high quality Cold work tool steel, It belongs to the high quality high carbon alloy tool Maximum Continuous Service Temperature Plastic PropertiesMax Continuous Service Temperature This is the maximum acceptable temperature above which mechanical properties (tensile strength, impact strength) or electrical properties ( dielectric strength , linked to insulation properties) of a plastic part are significantly degrading, over the reasonable life time of the tested product.Microstructures and properties of a novel carburizing After high temperature tempering, the 23Cr2Ni2Si1Mo steel was held at 860 °C for 1 h and austempered at 200 °C for 8 h. And the 20Cr2Ni4 steel was held at 810 °C for 1 h and then quenched in oil at once. In the end, the two steels were moved into a 200 °C furnace to temper.

What is the difference between application and service

May 24, 2017· Service temperature is the temperature to which your HVAC tape will need to withstand throughout the life cycle of the system after application. The risk for tape failure increases when tapes that are not built to regularly withstand extreme temperatures are used in HVAC systems. If your system will be exposed to temperatures under 32 degrees F Materials Free Full Text Bending Fatigue Behaviors A wide range of industrial applications use 20Cr2Ni4 alloys because of their excellent combination of mechanical ductility and fatigue resistance [].This alloy has the characteristics of good hardenability, surface hardness, wear resistance, toughness (after carburizing and quenching), low temperature impact toughness, anti contact fatigue, and gluing ability [].(PDF) Bending Fatigue Behaviors Analysis and Fatigue Life To investigate the relationship between inclusions and bending fatigue behaviors in 20Cr2Ni4 steel under different stress concentrations. and quenching), low temperature. impact toughness

IOP Conference SeriesMaterials Science and Engineering High temperature flow stress strain curves were measured over the deformation temperature range of 950 to 1050 °C and a strain rate from 0.01 to 10 s 1. Experimental results revealed that the peak stress decreases with increasing deformation temperature and decreasing strain rate. The 20Cr2Ni4 alloy steel has the properties of high
