Phosphorus is a very harmful element in A709 grade 50W carbon steel plate steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of A709 grade 50W carbon steel plate steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
The weldability of A709 grade 50W carbon steel plate is good. It means that under certain process and construction conditions, A709 grade 50W carbon steel plate can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
EN10025-6 S460QL structural steel plates are European standard low alloy high strength steel materials. A709 grade 50W carbon steel plate, S460QL steel plates are mainly used for building and engineering structures, such as plant structure, body steel frame components of bulldozers, loaders etc. all kinds of construction machinery, bridges, ships and so on.
