Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel scr420h hardness not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.
The table below compares steel equivalent grades of materials from various international specifications. Note that materials compared are the nearest available grade and may have slight variations in actual chemistry. SCr420, Chromium 1% Alloy, Low Alloyed : (Strength) (Hardness) (Corrosion-resisting), , (Self-hardening) . , . 1% SCM415 Steel | 15CrMo | 1.7262 | 15CD4.05-JIS G4105(1979 scr420h hardness The SCM415 Alloy steel will get MAX 235 HB Brinell hardness. Hardening of SCM415 Alloy steel SCM415 steels should be heated uniformly to 840-875C (1544-1607F) until completely heated through.
SAE-AISI 5120 steel is an alloy steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 5120 is the designation in both the SAE and AISI systems for this material. SAE AISI 4140 Steel Properties, Material Heat Treatment scr420h hardness SAE AISI 4140 Alloy Steel. SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature.

The hardness profiles after nitriding are calculated by experimental regression equation (4) and shown in Fig. 6 for SCr420H steel. The calculated hardness data result in good agreement with the measured ones. However, there are discrepancies between calculations and observations for the maximum hardness. Prediction of Phase Composition and Nitrogen Concentration scr420h hardness SCr420H steel. The chemical compositions of specimens are listed in Table 2 . The nitriding process parameters are shown in Fig. 3 . Hardness measurements on cross sections and the surfaces of nitrided specimens were carried out with a Vickers hardness tester. For the determination of nitrogen contents, Electron Probe X-ray Microanalysis Multi-stage cold forging and experimental investigation for scr420h hardness Furthermore, the microstructure before and after the spheroidizing heat treatment of SCr420H as the initial billet was also investigated as shown in Fig. 8a and b, and the hardness (HRB) of the billet was measured between 89.0 and 89.5 for the raw material and between 67.0 and 69.0 for the heat annealed one, by using a Rockwell hardness scr420h hardness
The hardness is then located on the Jominy curve for 1040 steel. But, the selected steel must have a hardness of R c 46 or higher at the same Jominy bar distance. Of the steels displayed, 5140, 8640, 4140, and 4340 will all meet the hardness specifications after heat treatment.
