ASTM A572 includes five grades with specified minimum yield strengths of 42, 50, 55, 60, and 65 ksi, respectively. For applications where notch toughness is important, consult SSAB for specific Charpy V-notch toughness requirements. ASTM A572 grades are used in a wide variety of structural applications in many market segments.
ASTM A709 - Preheat for Grade 50 - Welding, Bonding AWS D1.1 lists minimum preheat for Pre-Qualified WPS's with ASTM A709 Gr 50 3 to 20 mm inclusive = 0 degrees C (if base metal is less than 0 it shall be preheated to 20 degrees C minimum) Over 20 mm through 38 mm inclusive = 10 degrees C Over 38 mm through 65 mm inclusive = 65 degrees C Over 65 mm = 110 degrees C Hope that helps, Regards, DD
ASTM A709 VS ASTM A572 steel plate in - Bebon ChinaAnd ASTM A709 steel plate is utilized primarily in the manufacture of bridges. ASTM A709 steel consists of A709 grade 36, A709 grade 50 and A709 grade 50W, etc. ASTM A709 steel grades are often specified with Charpy tests referring the specific zone or lowest anticipated service temperature.
Also denoted by QT or Q/T, these steels are weldable, but care must be taken to adhere to established procedures at all times, as they often have high carbon contents, and thus high hardenability, leading to a hard heat-affected-zone (HAZ) and susceptibility to cracking. The BS EN 10277-5:2008 (old BS 970 Part 3) steels are good examples of these types of steel.

Grade 50 is used in general plate applications when the plate will be riveted, bolted, or welded. Grade 50 is a Columbium-Vanadium steel that offers a minimum yield of 50,000 PSI. In addition, ASTM A572 Grade 50 is noted for its increased resistance to atmospheric corrosion. Grade 50 contains more alloying elements than plain carbon steel and
SteelWise Do you 992 - AISCsteel, grade ASTM A709 Grade 50S.

Welding metals of dissimilar strengthsCertain joint designs may allow you to undermatch the filler metals strength to the lower-strength material. For instance, some fillet joints created by joining a 100-KSI yield, quench-and-tempered material like A514 to an even higher-strength, proprietary high-strength, low-alloy 130 material can accommodate welds with 70-KSI filler metals.
