SM490B is a structural steel produced according to Japanese standard JIS G3106, with a strength σb of 490MPa. This standard applies to bridges, ships, vehicles, petroleum storage tanks, manufacturing plants, general construction and various engineering machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, and excavators used in mines and various engineering constructions.
Manganese steel plates emerge as a profitable solution to diverse kinds of acid attacks. These have qualities surpassing an ordinary steel plate. Neither fully austenitic nor ferritic, these plates EN 10025-4 pdf provide boosted resistance to chloride stress corrosion cracking, which the 300 series stainless steel plates are susceptible to. 22% Chromium allows these plates to withstand Sulphuric and Hydrochloric acid attacks, whereas Molybdenum (up to 3%) avoids crevice and pitting corrosion.
When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the EN 10025-4 pdf, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.
