1. Scope
1.1 This Standard applies to steel sections (including wide flange beams), steel bars, wire rod, flat products(strip, plate, wide flats) seamless and
welded, square and rectangular hollow sections, forgings and semi-finished products in the general structural steels nemed in Tables 1 to 3 which are
delivered in the hot formed or normalized condition after production.
1.2 products from steels according to this Standard are for use in welded (but see Section 834.2), riveted and screwed structural components, They
are not intended for heat treatment - apart from stress-reliening heat treatment and normalizing.
1.3 This Standard does not cover the following products from steels for heneral structural purposes : Seamless and welded tubes and precision steel
tubes [see DIN 1626 Part 1 to Part 4, DIN 1629 Part 1 to part4, DIN 2391 Part2, DIN 2393 part 2, DIN 2394, DIN 2395 Part 2, DIN 2395 part3).
Steel castings(See DIN 1681).
Cold rolled flat products without coating (see DIN 1623 Part2, new version in preparation).
Flat steel products with coatings(DIN Standards in preparation).
Bright finished steel (see DN 1652).
Cold rolled sections (see DIN 17118).
Cold finished steel hollow sections (DIN Standards in preparation).
For notes on Standards and standard-tupe publications for steels with adjacent fields of application see the end of this Standard.
