How strong is Q345D carbon steel plate sheet?

The company has created a group of professional staff with good market awareness and service spirit. More than 90% of the company's employees have college education and more than 3 years of work experience in the industry. Our company has a group of senior professionals engaged in international cargo transportation. Through the implementation of modern centralized control management of the Q345D carbon steel plate sheet whole system computer network, we can effectively control and guarantee the daily operation of the Q345D carbon steel plate sheet. The company is dedicated to provide customers with safe, convenient, economic and thoughtful freight service. The company has always followed the principle of "people-oriented", and created a group of professional staff with good market awareness and service spirit.

S50C steel characteristics: the carbon content of the steel (mass fraction, %) ≥ 0.4, excellent wear resistance, reduced ductility, easy to deform and crack after quenching, so quenching is extremely important, and it must be quenched after cutting and tempering to avoid tempering brittleness. By implementing spheroidizing treatment, the cutting performance of this type of carbon steel keyword} can be improved. The steel is usually used after tempering to a hardness of 19~22HRC to increase its cutting performance.

Q345D carbon steel plate sheet, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

Heat treatment is a very important process to improve the performance of Q345D carbon steel plate sheet etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.

Q345D carbon steel plate sheet, 15CrMo alloy steel is Chinese material. It is characterized by high Chrome and Molybdenum contents. The 15CrMo alloy steel chrome content is 0.80-1.10, and molybdenum content is 0.40-0.55. Besides, 15CrMo carbon content is 0.12-0.18, silicon content is 0.17-0.37, manganese content is 0.40-0.70. The heating temperatures for quenching and tempering of 15CrMo alloy steel are 900 and 650 centigrade respectively. The yield point of 15CrMo alloy steel is 295Mpa.

We have a professional production team and high-quality production equipment, and we also have a great Q345D carbon steel plate sheet advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the Q345D carbon steel plate sheet production of high-quality steel plates, steel pipes and other products that meet customer requirements.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel Q345D carbon steel plate sheet plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
