Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the steel A283 grade C 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 steel a283 grade c 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.
When the steel a283 grade c thickness of the part is 14-20mm, the verticality of the section should not be greater than 12% of the thickness of the part.For their inspection mark, it is stipulated that: if the steel plate, section steel processing parts or stamping parts are inspected and qualified, the quality mark should be attached to prove that the inspection is qualified.
Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
Under the specification EN 10025-2, S275J2 plates are mainly used in the building industry and mechanical engineering, containers, storage tanks and roll formed steel profiles, such as steel angles, steel structures, H-beams, T-sections. For steel a283 grade c, S275J2 carbon steel, our engineers still suggest done normalized heat treatment for them if customers want to improve their steel's property when using. Else, this steel must be done low temperature impacting test at -20℃.
