Weldability of sa573gr.65 hot rolled structural steel strip

The weldability of sa573gr.65 hot rolled structural steel strip is good. It means that under certain process and construction conditions, sa573gr.65 hot rolled structural steel strip 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 steel adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality sa573gr.65 hot rolled structural steel strip, efficient and fast services. Facing the future, adhere to independent innovation.

The use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight. It must be noted that for components that may be bent, the allowable stress must be corrected to ensure the robustness of the structure. Sometimes low-alloy high-strength steel is used to replace sa573gr.65 hot rolled structural steel strip, carbon structural steel without changing the cross-sectional size. Its sole purpose is to obtain a stronger and more durable structure without increasing weight.
