China Q355NH HIC tested plate prices continue to decline

The company now has Q355NH HIC tested plate oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than Q355NH HIC tested plate 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than Q355NH HIC tested plate, ordinary carbon steel by adding less alloy elements. Q355GNH weathering steel has been widely used in container, railway vehicle, bridge, building and air preheater which need to be resistant to atmospheric corrosion. Q355GNH weathering steel is characterized by the addition of less Cu, P, Cr, Ni and other alloy elements in the steel, so that a dense amorphous spinel type oxide layer with a thickness of about 50-100μm is formed between the rust layer and the base metal, which can prevent oxygen and water from penetrating into the steel matrix, slow down the development of corrosion to steel materials, and improve the atmospheric corrosion resistance.

Alloy seamless pipe has good sealing performance and is often used in fluid transportation pipeline, such as pipelines for oil, water, natural gas, for which the steel pipe need to be buried underground for a long time. However, the alloy seamless pipe seldom causes leakage and the loss of resources can be reduced. The Q355NH HIC tested plate, alloy seamless pipe is smooth in surface, and has small resistance to the fluid in the pipeline, so it will not block the pipeline. It can make the fluid pass through smoothly, so as to improve the efficiency of fluid transportation and speed up the transportation speed.

Temperature has a great influence on the strength of the material, Q355NH HIC tested plate. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

A537 grade 70 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the Q355NH HIC tested plate, A537 grade 70 steel coil thickness should not exceed 25 mm. The mechanical properties of A537 grade 70 steel is yield strength is 290MPa, and the tensile strength is 485-620Mpa.

It is a modern high-tech professional enterprise integrating scientific research, Q355NH HIC tested plate 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 Q355NH HIC tested plate process technology development, technology transfer and related technical consulting and technical services.

The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
