The S420NL structural steel plate cold bending performance from BBN

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for S420NL structural steel plate various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several S420NL structural steel plate after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

The weldability of S420NL structural steel plate is good. It means that under certain process and construction conditions, S420NL structural 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.

BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.

The pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, S420NL structural steel plate is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.
