Medium thick steel plate refers to the steel plate with a thickness of not less than 3 mm but less than 20 mm. It can be produced by reversible hot rolling medium and heavy plate mill, and its thin products can also be processed by cold rolling mill. A283 grade D CS steel carbon plate, Medium thick steel plates are mainly used in boilers, shipbuilding, railway cars, automobiles, containers, military industry, national defense, construction, bridges and containers.
Our company is a large A283 grade D CS steel carbon plate steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special A283 grade D CS steel carbon plate steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.
The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the A283 grade D CS steel carbon plate steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the A283 grade D CS steel carbon plate steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.
The common delivery status of A283 grade D CS steel carbon plate, SA516 Gr 70 plate is as follows: 1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point. 2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air). 3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly. 4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A283 grade D CS steel carbon plate 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.
