What is the chemical composition of S420ML carbon steel plate sheet?

The company adopts the S420ML carbon steel plate sheet international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety S420ML carbon steel plate sheet management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

There are many types of S420ML carbon steel plate sheet etc. alloy steel plates, which can be divided into different types according to different standards. If divided according to the element composition of the alloy, the alloy steel plates can be divided into four types. The first is chromium steel, in which chromium is an important part of alloying elements. The second type is chromium-nickel steel, the third is manganese steel, and the last type is silico-manganese steel. The types of these alloy steel plates are named according to the composition of the alloying elements contained in the steel, so you can roughly understand their composition based on their names.

High wear resistance: fully automatic CNC stacking equipment, independent of manual S420ML carbon steel plate sheet welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the S420ML carbon steel plate sheet hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite S420ML carbon steel plate sheet wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.

The common delivery status of S420ML carbon steel plate sheet, SA516 Gr 70 plate is as follows: 1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point. 2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air). 3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly. 4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.
