Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the A514 Gr Q high strength steel plate project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of A514 Gr Q high strength steel plate customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
According to different strength levels, the ASTM A516 plates are available in four grades: Grades 55, 60, 65, and 70. The most common is Grade 70 or called out A516-70. The maximum thickness of {keyword plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. The mechanical properties such as tensile strength, yield strength, and elongation shall be determined by a tension test for the plates.
Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of A514 Gr Q high strength steel plate, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
Compared with A514 Gr Q high strength steel plate, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A514 Gr Q high strength steel 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.
