1、Designation:A 607 98Standard Specification forSteel,Sheet and Strip,High-Strength,Low-Alloy,Columbium or Vanadium,or Both,Hot-Rolled and Cold-Rolled1This standard is issued under the fixed designation A 607;the number immediately following the designation indicates the year oforiginal adoption or,in
2、 the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This sp
3、ecification covers high-strength,low-alloycolumbium,or vanadium hot-rolled sheet and strip,or cold-rolled sheet,or combinations thereof,in either cut lengths orcoils,intended for applications where greater strength andsavings in weight are important.The material is available astwo classes.They are s
4、imilar in strength level except that Class2 offers improved weldability and more formability than Class1.Atmospheric corrosion resistance of these steels is equiva-lent to plain carbon steels.With copper specified,the atmo-spheric corrosion resistance is twice that of plain carbon steel.1.2 The valu
