ASTM A515gr55 application,ASTM A515gr55 cold-rolled plate
A515gr55 is a steel gread in ASTM,Bebon International is ASTM A515gr55 supplier in China.
ASTM / ASME Materials Testing Association American standards, this standard is mainly used to improve the notch toughness important welding pressure vessel steel plate.
ASTM A515gr55 cold-rolled plate is hot rolled coils as raw material, after descaling by pickling cold rolling, the finished product is hard roll, due to continuous cold work hardening caused by the deformation of the hard roll strength, increased hardness, tough plastic index decreased, punching performance will deteriorate so, only for a simple deformation of parts. Hard roll hot-dip galvanizing plant can be used as raw material, as hot dip galvanizing line is provided with annealing line. Hard roll weight is generally from 6 to 13.5 tons, coil at room temperature for hot continuous rolling pickling. Inner diameter of 610mm.
ASTM A515gr55 application.ASTM A515gr55 for the manufacture of petroleum, chemical, petrochemical, gas separation and storage of gas pressure vessel or other similar equipment steels. Operating temperature is generally -20 ℃ to 500 ℃.
