A709 Gr50 plate is a structural steel for bridge, also known as high strength low alloy steel plate. A36 hot rolled mild carbon steel plate, A709 Gr50 steel is widely used in engineering structures, such as building steel structure, construction machinery, mining machinery, truck, bridge, pressure vessel, etc., especially for construction and engineering machinery parts requiring good weldability and toughness.
The weldability of A36 hot rolled mild carbon steel plate is good. It means that under certain process and construction conditions, A36 hot rolled mild 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.
In terms of service, our service is a "one-stop" way of working. We have our own A36 hot rolled mild carbon steel plate processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as A36 hot rolled mild carbon steel plate cutting, welding, drilling, galvanizing, etc., at the lowest cost.
