2.1.2.2
Quenched and Tempered Alloy Steel
**************************************************************************
NOTE: ASTM A 514 steel has a minimum yield strength
of 690 MPa up to 65 mm thickness and 620 MPa for 65
mm to 150 mm thickness 90 to 100 ksi, depending on
size, and is used for dynamically loaded structures
and provides good notch toughness and abrasion
resistance. ASTM A 514 covers 13 grades of steel,
each with a different chemical composition and
thickness. Unless a special chemical composition is
desired, specifying a certain grade of ASTM A 514
steel is usually not required. Check availability
of grades before specifying; normally only Grades A,
F, H, and Q are stocked.

2.1.2.3
Quenched and Tempered Low-Alloy Steel
**************************************************************************
NOTE: Check the availability of ASTM A 852. It has
been found that in some cases it is not available in
small quantities.

2.1.3
Weathering Structural Steel
**************************************************************************
NOTE: Weathering steels provide atmospheric
corrosion resistance of approximately four times
that of carbon steel without copper (normal ASTM A
36/A 36M steel) in non-marine environments. ASTM A
242 steel has a minimum yield strength of 290 to 345
MPa 42 to 50 ksi (depending on size). ASTM A 588
steel has a minimum yield strength of 290 to 345 MPa
42 to 50 ksi (depending on size) and is available
in four grades of steel, each with a different
chemical composition. Unless a special chemical
composition is desired, specifying a certain grade
of ASTM A 588 steel is not required.

NOTE: ASTM A 529/A 529M steel is routinely used for
steel forging. This steel has a minimum number of
