The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. JIS carbon steel SM570 CS plate, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
Steel material has an irreplaceable role in many projects, especially in building construction, bridge cofferdams, road construction, foundation pit support, garden engineering, excavator paving, subgrade engineering and other projects. Therefore, the quality of JIS carbon steel SM570 CS plate steel material can not be ignored, so how should customers identify the authenticity of steel when choosing steel materials? Today we would like to analyze it together. So that it can help you to purchase satisfied steel materials in the future.
According to Indonesia's Minister of Energy and Mining, Arifin Tasrif, Indonesia has 23 ferronickel smelting plants. The Indonesian Ministry of Energy and Minerals expects that the production of ferronickel will rise to 2.1 million tons in 2021, a year-on-year increase of 45%. In 2020, Indonesia's ferronickel production will increase by 45%. The output is only 1.45 million tons.
