hardnes of hardox 500 sheet sheet properties and usage

Pipeline steel refers to a type of steel with special requirements used for the transportation of oil, natural gas and other pipelines. Depending on the thickness and subsequent formation, pipeline steel can be produced by hot continuous rolling machines, furnace coil machines or plate machines, and formed into large-diameter steel pipe by spiral welding or UOE straight seam welding. The current development trend of hardnes of HARDOX 500 sheet pipeline engineering is large-diameter, high-pressure rich gas transportation, high cold and corrosive service environment, and thickening of submarine pipelines.

The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the hardnes of HARDOX 500 sheet industry, keep pace with the times, and move towards a new course!

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the hardnes of HARDOX 500 sheet steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the hardnes of HARDOX 500 sheet steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with hardnes of HARDOX 500 sheet, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel hardnes of HARDOX 500 sheet products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
