ABS Grade E Shipbuilding Steel Pipe Application
ABS Grade E steel is done low temperature impacting test when rolling in our steel mill.In addition to the basic requirements of this specification for steel pipe ABS Grade E,certain supplementary requirements are available when additional control, testing, or examination is required to meet end use requirements.Shipbuilding steel pipe ABS Grade E mainly be used in below minus 40 centigree ocean situtation.
