Firstly,what is an alloy? This is a material comprising two or more elements,at least one of them a metal.Alloys achieve better specific characteristics than their constituent parts,and steel is itself an alloy of iron..Alloy steels are steels in which additional elements have been added to the usual iron,carbon,manganese and silicon that is present in ordinary carbon steels in order to Steel Glossary Glossary of Terms PlattsThe very demanding operational conditions mean drill pipe is always seamless.Casing acts as the liner and structural wall of oil/gas wells,preventing contamination of the well and of the surrounding water table,and can be up to 26in dia.Casing accounts for about three quarters of all OCTG shipments.The third type is oil well tubing.This Steel Grades Specifications - RFLThis has resulted in the removal of this grade from the standard,and the lowest grade now offered is the JR version for each yield strength variation.EN 10025 2004 is the new European standard for structural steel.EN 10025 2004 is the new European standard for structural steel
