Q490R is a pressure equipment with tempered high-strength steel plate, instead of grade 07MnMoVR, steel grade by the yield strength "yield" on behalf of the initial letters of the hanyu pinyin "Q", the minimum yield strength value of the provisions of 490, the pressure vessel "Yung" character of the initial letter of the hanyu pinyin "R" composition.
Q490R steel plate implementation standard: GB/T713.6-2023, instead of the original standard GB/T19189-2011, this standard specifies the pressure equipment with tempered high-strength steel plate grade representation, order content, size, shape, weight, technical requirements, test methods, inspection rules, packaging, marking and quality certificates; this standard applies to the thickness of 10 ~ 80mm This standard applies to the thickness of 10 ~ 80mm pressure equipment with tempered high-strength steel plate.
Q490R steel plate delivery status: steel plate should be quenched and tempered tempered heat treatment state delivery, of which the tempering temperature is not less than 600 ℃.
Q490R is a kind of high-strength steel plate for pressure vessels, which is mainly used for manufacturing equipment in petroleum, chemical, power station, boiler and other industries.Q490R has excellent mechanical properties and corrosion resistance, and can meet the needs of various complex environments and uses. In the industrial field, Q490R steel plate is widely used.
