What is the rolling q345r properties plate

The company adopts the q345r properties 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 q345r properties 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.

Wear resistant steel plate q345r properties is widely used in engineering, mining, construction, agriculture, cement production, port, electric power, metallurgy and other mechanical products, which require high strength and wear resistance. Such as bulldozers, loaders, excavators, dump trucks and various mining machinery, grab, stacker reclaimer, conveying bending structure, etc. The wear resistant steel plate q345r properties can obtain good combination of strength and toughness through scientific quenching and tempering process, which can also improve the steel hardness to achieve the purpose of wear resistantance.

q345r properties, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. q345r properties, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. q345r properties, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.

With the increase of temperature, the yield limit of q345r properties will decrease monotonically, but the tensile strength of q345r properties will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of q345r properties. Near the blue brittleness temperature, the q345r properties strength increases and the plasticity decreases. The elongation and section shrinkage of q345r properties increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

It is a modern high-tech professional enterprise integrating scientific research, q345r properties production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as q345r properties process technology development, technology transfer and related technical consulting and technical services.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the q345r properties principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
