What are the main items of mechanical property inspection of ASME SA283 carbon steel plate sheet

The mechanical properties of ASME SA283 carbon steel plate sheet, Q690E plate:The thickness of Q690E plate is not more than 50mm, the yield strength is not less than 690MPa, the tensile strength is 770-940, and the elongation after fracture is not less than 14.The thickness of Q690E plate is 50mm-100mm, the yield strength is not less than 650MPa, the tensile strength is 760-930, and the elongation after fracture is not less than 14.The thickness of Q690E plate is 100mm-150mm, the yield strength is not less than 630MPa, the tensile strength is 710-900, and the elongation after fracture is not less than 14.

In the past 10 years, domestically-made offshore platform steel has been widely adopted in China's offshore oil projects, and offshore platform steel has gradually developed in the direction of high strength. Relevant data show that the pile legs, pile boots, cantilever beams and other key parts of the jack-up platform require high load. In order to improve the stability of the hull during towing after floating, it needs to be lightweight, and high-strength steel plates must be used.

As a common steel plate in the steel market, ASME SA283 carbon steel plate sheet, manganese steel plate has the following characteristics. First, good toughness, stretching and crimping can be done well. Second, the bearing strength of manganese steel plate is good and it can bear a lot of gravity. Third, the ASME SA283 carbon steel plate sheet, manganese steel plate is easy to weld, easy to process finished products, and its price is relatively low. Fourth, manganese steel plate has good corrosion resistance, and long service life. Fifth, the manganese steel plate has good mechanical properties, low temperature performance, good plasticity and weldability.
