hr steel coil A36, S355J0 steel density is 7.85g/cm³. S355J0 density represents the mass per unit volume of S355J0 steel, which indirectly affects the price of S355J0 steel. Therefore, the density of S355J0 is also an important consideration for material selection. S355J0 steel tensile strength (σb / MPa):3
After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the hr steel coil A36 plate should be derusted before cutting.
Enterprise style: unity, pragmatism, responsibility, and endeavorOperation Policy: realistic management, innovative technology, high quality, fast efficiency, low cost and complete service. Enterprise spirit: every year, every day, we should make progressEnterprise development is a process of continuous pursuit of progress. This spirit is reflected in the whole three-dimensional space of every person, every event and every time point in our enterprise. We should always continue to explore, break through and improve.
Laser welding processing is a new type of welding method, which is the welding processing of high-tech materials. Laser welding is mainly used for the welding of thin materials and precision parts. The welding process for hr steel coil A36 is rapid heat conduction welding.
