Are Quenched and Tempered (Q A709Grade 50 Sudan weldingamp;T) Steels Readily Weldable?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 - AISCseveral reasons. From a welding stand-point, the specified upper limit on yield strength in ASTM A992 signifi-cantly reduces the possibility of the weld metal becoming under-matched. This in turn reduces the potential for brittle fracture. Also, ASTM A992 is a prequalified base metal per AWS D1.1:02 Table 3.1. Designers should specify it is be-
Unfortunately, welding AR plate to softer or lower-strength steels (usually A36 or A572) brings with it the potential for cracking in the heat-affected zone (HAZ) of the AR plate. Here, you need to use a joint design such as a short, small fillet weld that can reduce heat input and overall residual stresses on the AR plate, and also find a

These grades are often specified with Charpy tests referencing the specific zone or lowest anticipated service temperature. The Charpy tests are specified as non-fracture critical, which is a per-heat test (frequency A709Grade 50 Sudan weldingquot;H A709Grade 50 Sudan weldingquot;), or fracture critical, which is a per-plate test
