ST52 steel angle steel with carbon content of 0.23% and yield point strength of 355 MPa is suitable for weldable and supporting members. In terms of chemical composition and mechanical properties, s355n is similar to A709 Gr 100 bridge steel plate en10025 - 3. Compared with ASTM A36, ST52 has higher strength and better welding performance. It is also used in daily life and industrial applications such as warehouses, equipment, etc. Note: although similar A709 Gr 100 bridge steel plate properties are shared, they are a little different. Please let us know your detailed requirements and we will tell you the most suitable steel grade.
The difference between Q195 steel and 20# steel: A709 Gr 100 bridge steel plate, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.
Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter A709 Gr 100 bridge steel plate steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
It is a modern high-tech professional enterprise integrating scientific research, A709 Gr 100 bridge steel 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 A709 Gr 100 bridge steel plate process technology development, technology transfer and related technical consulting and technical services.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
