In recent years, in line with the development trend of iron and sa573 gr.70 and sa709 grade 50 steel comparison steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which sa573 gr.70 and sa709 grade 50 steel comparison are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Q550B steel is a low-alloy high-strength structural steel grade. Steel Q550A is not required for impact toughness test; Q550B is for impact toughness test at room temperature (20℃); Q550C is for 0℃ impact toughness test; Q550D is for impact toughness test at -20℃; Q550E grade is for impact toughness test Make impact toughness test at -40℃. The impact toughness test uses Charpy V-notch specimens. The impact toughness index is Akv.
What are the characteristics of medium and thick plate, sa573 gr.70 and sa709 grade 50 steel comparison? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, sa573 gr.70 and sa709 grade 50 steel comparison is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
The alloy wear-resistant layer of sa573 gr.70 and sa709 grade 50 steel comparison, wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is fibrous distribution, and the fiber direction is vertical to the surface. The alloy carbide has strong stability at high temperature, maintains high hardness, and has good oxidation resistance. It can be used normally within 500℃.
sa573 gr.70 and sa709 grade 50 steel comparison, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.
