How can high precision be achieved during laser cutting of 1.8909 equivalent

We have 4 typical production lines 1.8909 equivalent, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.

Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates 1.8909 equivalent for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our 1.8909 equivalent steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge 1.8909 equivalent steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for 1.8909 equivalent and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
