Promotion price A516 grade 60 pressure vessel steel sheet

Q690D material is a Chinese standard high-strength welded structural steel. What does Q690D stand for? Q represents the yield strength, 690 represents the yield strength value, and D represents the quality of the Q690 steel. The quality grades are A, B, C, D, and E, respectively. The impact of Grade D steel plate is﹣20°C. Q690D executive standard: GB / T1591-2008. A516 grade 60 pressure vessel steel sheet, Q690D steel has high yield strength and tensile strength.

The company is a leading company that sells A516 grade 60 pressure vessel steel sheet steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold A516 grade 60 pressure vessel steel sheet steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

The correct choice of billet type, section shape, size and weight are of great significance to A516 grade 60 pressure vessel steel sheet steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The A516 grade 60 pressure vessel steel sheet rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.

With the increase of temperature, the yield limit of A516 grade 60 pressure vessel steel sheet will decrease monotonically, but the tensile strength of A516 grade 60 pressure vessel steel sheet will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of A516 grade 60 pressure vessel steel sheet. Near the blue brittleness temperature, the A516 grade 60 pressure vessel steel sheet strength increases and the plasticity decreases. The elongation and section shrinkage of A516 grade 60 pressure vessel steel sheet increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

Our company will accept the product quality objection registration record, pass it to the A516 grade 60 pressure vessel steel sheet production unit and relevant departments, and timely coordinate the supervision of product A516 grade 60 pressure vessel steel sheet quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
