API 5L L320 PSL1 steel plate property of yield strength

The difference between q345 and q235 steel API 5L L320 PSL1 steel plate
The lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character ""qu"", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.

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 API 5L L320 PSL1 steel plate steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge API 5L L320 PSL1 steel plate 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.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the API 5L L320 PSL1 steel plate product workpiece, thereby improving the production efficiency and production processing quality.

Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. API 5L L320 PSL1 steel plate, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
