Welcome to BBN High Strength Steels Factory

The S550QL steel is a highly cost effective alternative

Steel material has an irreplaceable role in many projects, especially in building construction, bridge cofferdams, road construction, foundation pit support, garden engineering, excavator paving, subgrade engineering and other projects. Therefore, the quality of S550QL steel steel material can not be ignored, so how should customers identify the authenticity of steel when choosing steel materials? Today we would like to analyze it together. So that it can help you to purchase satisfied steel materials in the future.

Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, S550QL steel are strict. In the chemical composition of boiler steel, S550QL steel, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.

Steel plate S550QL steel cutting, according to different classification standards, there are different specific types. If it is divided by cutting temperature, it can be divided into cold cutting and hot cutting. One of the cold cutting, there are water jet cutting and abrasive cutting and so on, thermal cutting is flame cutting, plasma cutting and laser cutting. In addition, we also need to know that the high-grade thick S550QL steel steel plate can be cut by flame, and its cutting is as simple as that of ordinary low-carbon and low-alloy steel, but we need to pay attention to it.

The company always adheres to the quality policy of "Quality First, Continuous Improvement, Customer Satisfaction" and the business philosophy of "Continuous Progress, Pursuing Excellence", as always, we look forward to cooperating with you to create a new situation for common development.Steel products S550QL steel price concessions, rich industry experience, complete varieties.
