How Much Do You Know About Boiler SteelThe structure is required to be uniform, and the grain size is controlled within a certain range (between 3 and 7); 12Cr1MoVR and US ASME SA-387/SA387 M chromium-molybdenum alloy steel plate for pressure vessel Gr22, Gr91 and ASME SA1017/SA1017M pressure vessel for chromium-molybdenum-tungsten alloy steel plate Gr23, Gr911, Gr122 steel, etc
The impact toughness of low-Cr heat-resistant steel weld metal is an important problem to broaden the application of low-Cr heat-resistant steel. In this study, the microstructure and impact toughness of 12Cr1MoVR low-alloy heat-resistant steel weld metals with various boron contents (B1 = 0.0028%, B2 = 0.0054%, and B3 = 0.0079%) were investigated. The microstructures of all weld metals were
National Standards of the Peoples Republic of China12Cr1MoVR steel plates with a thickness greater than 60 mm can be delivered either annealed or tempered. The test samples of these coded steel plates should be heat-treated under delivery conditions according to Table 2 and their performance should meet the requirements of Table 2. The size of the samples should be no
