Petroleum, petrochemical and natural gas industries. Test methods for quality control of microstructure of ferritic/austenitic (duplex) stainless steels
石油、石化和天然气工业 铁素体/奥氏体(双相)不锈钢微观结构质量控制的试验方法
BS EN ISO 17781:2017 specifies quality control testing methods and test conditions for the characterization
of microstructure in relation to relevant properties in ferritic/austenitic (duplex) stainless steel
components supplied in the solution annealed condition and fabrication welds in the as welded
condition.This document supplements the relevant product and fabrication standards with respect to destructive
testing methods including sampling of test specimens, test conditions and test acceptance criteria to
show freedom from deleterious intermetallic phases and precipitates in duplex stainless steels. In
addition, this document specifies the documentation of testing and test results by the testing laboratory.Cross References:ASTM G48ASTM E1245ASTM E562ASTM A1058ASTM A370ASTM A1084ASTM E3ISO 15614-1:2017ISO 148-1:2016DNV/GL RP-F112ASTM E407ISO 15156-3:2015All current amendments available at time of purchase are included with the purchase of this document.
