Sep 18, 2002 · ASTM A36 steel is classified as AWS Group I material and, as such, may be welded with non-low-hydrogen processes. In contrast, ASTM A572 Grade 50 steel is classified as AWS Group II material, which, because of its higher yield strength, must be welded using low-hydrogen processes.
A572 ASTM A572 Steel A572 Steel Plate Kloeckner A572 plate is a high-strength, low-alloy structural steel that includes five grades42, 50, 55, 60, and 65according to their minimum specified yield strength. For applications requiring notch toughness, Kloeckner Metals also supplies A572 charpy tested.
Universal Steel stocks A572-50 from 3/16 thick up to 4 thick, and A572-42 above 4 thick up to 6 thick. A572 is used in structural applications where strength and notch toughness are more critical than the general A36 requirements. Standard stock is provided in the as-rolled condition; however, normalized material can be obtained.
A572 gr 50 - American Welding SocietyMar 10, 2008 · Im having problems with cracking in the welds and right next to the welds on 2 1/2 " inch thick flanges on colloums A572 Gr 50. We have tried several pre heats from 150 up to 450. We are also doing a controlled coolling with insulation pillows. The rods we are using is a 7018 h4r lincoln rod.
A572-50 SteelA high strength, low-alloy steel, A572-50 is used in general plate applications when the plate will be riveted, bolted or welded. Resistant to atmospheric corrosion, A572-50 is commonly used in structural applications, heavy construction equipment and building structures.

ASTM A572 Steel - Ultra-High Strength - CopperloyA572 Grade 50 has a 139% greater Yield Strength than A36 steel. A572 steel does not require preheat or post heating during the welding process and standard AWS D1.1 welding standards apply. Higher grades of steels will require preheating which is not economical compared to savings in weight. Welding wire for A572 Grade 50 that is used has a
ASTM A572 steel plate is made of ASTM AA572, a High-Strength Low-Alloy, Columbium-Vanadium Structural Steel. There are five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades 42 , 50 , and 55  are best for riveted, bolted, or welded structures. Grades 60  and 65  are best
CE 405:Design of Steel Structures Prof. Dr. A. Varma Example 3.1 A 5 x ½ bar of A572 Gr. 50 steel is used as a tension member. It is connected to a gusset plate with six 7/8 in. diameter bolts as shown in below. Assume that the effective net area Ae equals the actual net area An and compute the tensile design strength of the member. b b a a 5 x ½ in. bar Gusset plate 7/8 in. diameter bolt A572 Gr. 50 Solution
Welding A572 Gr 50 - Welding, Bonding & Fastener Aug 01, 2006 · After this piece is welded it will be welded to the outisde of a cylinder mesuring 72 3/4" OD by 60" long and 3/8" thick. The cylinder is A36 steel. I plan to use a 45 degree single bevel groove weld to form a T-joint between the cylinder and the 1"x5" plates, with a 1/8" root face and and no root opening. I plan to use the same wire and gas.
