A514 steel plate is high strength weldable steel quenched and tempered according to ASTM standard. ASTM A514 steel plate is mainly used in places where A283 Gr B CS steel carbon plate high tensile strength and high yield are required. The lifting gears of engineering vehicles, and racks for offshore platforms generally use A514 grade Q or A514 Gr Q. The A283 Gr B CS steel carbon plate hardness of A514 steel plate is between 235-290. A514 steel yield strength is more than 630MPa, and tensile strength is more than 700MPa. A514 steel plate is difficult to process. In the United States, the use of A514 steel plate is very large.
The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced A283 Gr B CS steel carbon plate production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, A283 Gr B CS steel carbon plate steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A283 Gr B CS steel carbon plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A283 Gr B CS steel carbon plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the A283 Gr B CS steel carbon plate plate should be derusted before cutting.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
