At the same time of doing well in A514 grade P structural steel material production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A514 grade P structural steel material technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
Steel S275J0 is a carbon structural steel grade. Our mill can produce S275J0 carbon steel plates up to 400mm thickness. Generally speaking, as rolled condition for S275J0 carbon steel plate is Ok. Our mill would like to provide customers' normalized delivery condition if they indicate in their purchase order. A514 grade P structural steel material, Structural steel S275J0 has a specified minimum yield strength at ambient temperature of 275MPa when plates thickness less than 16mm.
The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, A514 grade P structural steel material, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than A514 grade P structural steel material. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel A514 grade P structural steel material is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
