The use of A633 Grade D mild steel high strength carbon steel is still faced with some problems

The company has superior geographical position and convenient transportation. Our main steel products are: low alloy high-strength plate, carbon structural plate, alloy structural plate, bridge plate, building structural plate, shipbuilding and offshore oil production platform plate, boiler and pressure vessel plate, pipeline plate, weathering steel plate, A633 Grade D mild steel high strength carbon steel, etc.. In line with the principle of "not striving for the lowest price, but the best quality", the company wholeheartedly provides high-quality steel products and sincere services for users at home and abroad.

The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. A633 Grade D mild steel high strength carbon steel, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.

Cold rolled A633 Grade D mild steel high strength carbon steel steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner A633 Grade D mild steel high strength carbon steel steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate A633 Grade D mild steel high strength carbon steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A633 Grade D mild steel high strength carbon steel plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
