HISTORY OF STEEL GRADES (Canam Canada) YEAR DESCRIPTION 1961 Start of production at the St.Gédéon de Beauce plant (Quebec) Steel A6 Fy = 36 ksi 1970 Round bar Fy = 44 ksi (equivalent to G40.21 44W steel) Coils used for cold-formed angles Fy = 50 ksi (equivalent to G40.21 50W steel) results for this questionHow are the different types of structural steel classified?How are the different types of structural steel classified?Structural steels are classified by the shape of their cross-sections,such as the most frequently used I,T,C shapes (2).Besides their shape,the grade of the steel directly affects the mechanical properties.So,different grades of structural steel must be chosen according to different design requirements.A COMPREHENSIVE GUIDE TO STRUCTURAL STEEL - Yena Engineering results for this questionWhat are the former standards of steel?What are the former standards of steel?former standards include EN10025 1993.The European Committee for Iron and Steel Standardisation is responsible for producing the European Standards (ENs) for structural steels.The first of these standards,EN 10025,was published in the UK by BSI as EN10025 1990,partly superceeding BS 4360 1986,which was re-issued as BS 4360 1990.Steel Grades Specifications - RFL
With respect to steel grades and their availability,this is the current situation.Although common structural steels,such as CSA G40.21 Types W and A steels generally possess notch toughness that is superior to many steel products used for non-structural applications,they are not produced to meet specific impact testing requirements.1950's Rebar Yield Strength - Structural engineering ACI 318-56 gives the Allowable Tensile Stress as 20,000 psi for intermediate and hard grades and 18,000 psi for structural grade bars.It is the earliest that I have access to.Hope this is of some help.PS Price was $1.00 and it was 75 pages long (6 x 8).gjc
RE 1970 Structural Steel Grade BAretired (Structural) 19 Nov 13 19:45 In Canada,the 1967 Canadian Steel Handbook shows that the prevalent structural steel was G40.21 which is listed as having a yield of 44ksi but ASTM A36 and ASTM A441 were also available at that time.A COMPREHENSIVE GUIDE TO STRUCTURAL STEEL - YenaStructural Steel Types and Grades .There is not just one type of structural steel.There exist various different shapes and grades,depending on the needs for that specific application.Structural steels are classified by the shape of their cross-sections,such as the most frequently used I,T,C shapes (2).Besides their shape,the grade of AASHTO M 270M/M 270 - Standard Specification for AASHTO M 270M/M 270.January 1,2005.Standard Specification for Structural Steel for Bridges.This specification covers carbon and high-strength low-alloy steel structural shapes,plates,and bars and quenched-and-tempered alloy steel for structural plates intended for use in bridges.

We do not see this steel specified for vessel work.A-36 is the standard specification for all structurals and flat bars.Most of it comes from the melting and casting of steel scrap.The A-516 family of steels A-516 can be produced to Grades 55,60,65 and 70.A-516-70 is the most common and will be what is offered in steel warehouses worldwide.Evaluation of Existing Structures - AISCremained the primary structural steel standard until the early 1960s when ASTM A36 became the predominant structural steel used for building construction.Other types of high-strength,low-alloy steels were also developed and permitted for use in the 1960s.Often,these higher-strength steels would be used for applicationsFile Size 102KBPage Count 3Historic Structural Steelwork Handbook - SteelSTRUCTURAL STEELWORK HANDBOOK Properties of U.K.and European Cast Iron,Wrought Iron and Steel Sections including Design,Load and Stress Data since the Mid 19th Century Published by ©The British Constructional Steelwork Association Limited 4 Whitehall Court,Westminster,London SW1A2ES Telephone 071-839 8566 Compiled and Written by W.Bates
