API2HGr50 delivery status: steel is usually delivered in hot rolled or hot forged state. It can also be delivered in the state of heat treatment (annealing, normalizing or high temperature tempering). Annealing: The steel S690QL equivalent is heated to a suitable temperature and slowly cooled according to the heating time of different materials and specifications. Normalizing: Heat the steel plate to a suitable temperature and cool it in the air. Tempering: Keep the steel plate at an appropriate temperature for a long time while keeping it cool.
The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, S690QL equivalent. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.
With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of S690QL equivalent etc. steel material.
