Technology Cold Drawn, Hot Rolled, Hot Expanded Stocks delivery immediately Standard API 5L,ASTM A53/A106/JIS G3454/JIS G3455/DIN/EN10210 A comparative study on JohnsonCook, modified Abstract The isothermal hot compression tests were conducted on a Gleeble-1500D thermal simulation machine, in a wide range of temperatures (11731373 K) and strain rates (1.5 × 1031.5 × 102 s1). Based on the experimental true strain-true stress data, the JohnsonCook, modified JohnsonCook and Arrhenius-type constitutive models were established for a 20CrMo alloy steel.

A comparative study on JohnsonCook, modified

Dec 01, 2013 · The three strainstress constitutive models were established based on the experimental data of 20CrMo alloy steel during continuous casting and rolling in a deformation temperature range of 11731373 K and in a strain rate range of 1.5 × 10 3 1.5 × 10 2 s 1. Using these models, the simulation accuracy of mechanical behavior of the steel in the above-mentioned ranges can be Cause analysis of slag hanging in S500MC farm machinery Nov 30, 2020 · The service temperature of high pressure seamless steel pipe is below 450 , and the domestic pipes are mainly made of S500MC farm machinery steel, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions.

Chromium Molybdenum Steel and High Temperature

Nov 20, 2017 · Chromium Molybdenum Steel and High Temperature Applications. Chromium-molybdenum alloy steel (or chrome moly), is an alloy used for high pressure and temperature use. It is used in oil and gas, energy, construction and the automotive industries because of its corrosion resistance and high-temperature and tensile strength. The added reliability Coatings Special Issue :Surface Modification and Protective coating is an effective way to extend materials high-temperature service life. In order to improve the high-temperature oxidation resistance of AISI 304 stainless steel, mullite films with different layers were successfully prepared by the sol-gel method Research on the Cutting Performances and Wear Feb 07, 2019 · Physical vapour deposition technique was used to deposit TiAlCrN coatings on the YT15 tungsten carbide inserts. The dry turning tests of 20CrMo steel were carried out to evaluate performances of TiAlCrN coated and uncoated tools on the CA6140A lathe. The effect of the two kinds of tools on cutting forces, cutting temperature, surface roughness and tool wear had been investigated to assess
