Effect of Boron on properties of EN 10025-4 S420ML pdf

The company regularly holds sales elites to share experiences, to promote the rapid growth of colleagues, and achieve the company and employees. The company conducts employee skill training and related knowledge video learning from time to time. All these things is to improve the employees' skills and literacy, and reflects its own value. It has always been the pursuit of BBN steel to enhance the employee’s ability and keep up with the times.

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as EN 10025-4 S420ML pdf, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for EN 10025-4 S420ML pdf, 42CrMo steel is quenching and tempering.
