Standard: ASTM A242 - Standard Specification for High-Strength Low-Alloy Structural Steel
Purpose: This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction intended primarily for use as structural members where savings in weight or added durability are important. The atmospheric corrosion resistance of the steel in most environments is substantially better than that of carbon structural steels with or without copper addition. This specification is limited to material up to 4 in., Inclusive, in thickness.
Criteria: ASTM A242 is a specification with minimum requirements listed to meet this standard.
Usage: ... Shall meet the requirements of ASTM A242
Standard: ASTM A588 - Standard Specification for High-Strength Low-Alloy Structural Steel with 50 ksi Minimum Yield Point to 4-in. Thick
Purpose: This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability are important. The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition. This specification is limited to material up to 8 in. Inclusive in thickness.
Criteria: ASTM A588 is a specification with minimum requirements listed to meet this standard. Several composition "Grades" are available if detailed specification is required (A, B, C, K)
Usage: ... Shall meet the requirements of ASTM A588 -or- ... Shall meet the requirements of ASTM A588 Grade X
Standard: ASTM A262 - Standard Practices for Detecting Susceptibility to Intergranular Attack in Austenitic Stainless Steels
Purpose: ASTM A262 is used to detect susceptibility to intergranular corrosion in stainless steel. This test procedure covers five tests; Practice A, B, C, E, and F.
Criteria: ASTM A262 Practice A is used as a pre-screening test for acceptance testing of austenitic stainless steel, with other Practices used when Practice A fails. For rail applications, Practice E covers most of the alloys used. Typically used for structural stainless steel applications.
Usage: ... shall be tested for susceptibility to intergranular corrosion according to the requirements of ASTM A262, Practice X
Standard: ASTM A514 - Standard Specification for High-Yield-Strength, Quenched and Tempered Alloy Steel Plate, Suitable for Welding
Purpose: This specification covers quenched and tempered alloy steel plates of structural quality in thickness' of 6 in. [150 mm] and under intended primarily for use in welded bridges and other structures.
Criteria: ASTM A514 is a specification with minimum requirements listed to meet this standard. Several composition "Grades" are listed with detailed specifications for each (A, B, C, D,...). Common usage is for Grade F.
Usage: ... Shall meet the requirements of ASTM A514, Grade F
Standard: ASTM A27 - Steel Castings, Carbon, for General Application
Purpose: This specification covers carbon steel castings for general applications that require up to 70 ksi [485 MPa] minimum tensile strength. The grades covered by this specification represent materials that are suitable for assembly with other steel castings or wrought steel parts by fusion welding. Weldability, suitable welding technique and application is the responsibility of the user.
Criteria: Several grades are given with criteria for including Class of treatment. The standard should be reviewed and criteria selected along with the design criteria.
Usage: ... Shall meet the requirements of ASTM A27 , Grade XX, Class X
