ASTM A 242 GR. 1 steel plate, A588 grade B structural steel plate, A 242 GR. 1 steel plate, under ASTM standard, we can regard A 242 GR. 1 steel plate as Steel Resistant to Atmospherical Corrosion A 242 GR. 1 steel plate is one mainly of Steel Resistant to Atmospherical Corrosion, A 242 GR. 1 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.
Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. A588 grade B structural steel plate, Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A588 grade B structural steel 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 A588 grade B structural steel 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.
The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, A588 grade B structural steel plate and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A588 grade B structural 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.
