Supply A573Gr.70 european steel equivalent for bolted and welded structures product catalog free

A573Gr.70 european steel equivalent for bolted and welded structures, Steel pipes are widely used in our life, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Steel pipe can also be used to manufacture building structure grid, prop and mechanical support, which can reduce weight, save metal by 20-40%, and realize factory mechanized construction. For steel pipes on the market, in fact, there are seamless pipes and welded steel pipes. If not purchasing often, buyers will easily ignore their models and some material problems.

Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, A573Gr.70 european steel equivalent for bolted and welded structures.

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 A573Gr.70 european steel equivalent for bolted and welded structures 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.
