What harm does the excessive weld height of 05CuPCrNi steel tube bring

Q420B material is a low-alloy high-strength structural steel. 05CUPCRNI steel tube, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.

The price of common carbon plate is relatively low compared with other kinds of steel 05CUPCRNI steel tube, and it can be used in a wide range of occasions, such as construction, machinery manufacturing, etc. Therefore, carbon plate is favored by users all over the world. And because of its large demand, fast circulation, the steel suppliers and exporters would like to keep huge carbon plate stocks, and thus the delivery is very quick. We also have large quantity stock for carbon plates. And we provide further processing for the carbon plate.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This 05CUPCRNI steel tube method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.

It is a modern high-tech professional enterprise integrating scientific research, 05CUPCRNI steel tube 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 05CUPCRNI steel tube process technology development, technology transfer and related technical consulting and technical services.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
