At the same time of doing well in A514 Gr Q 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 Gr Q 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.
P355GH is the European standard pressure vessel plate and sheet. The implementation standard: EN10028-2:2003. A514 Gr Q structural steel material, EN P355GH steel plate and sheet has good plasticity, toughness, cold bending performance and welding performance, suitable for manufacturing nuclear island steel containment, pressure vessels, equipment structural parts, etc. It is delivered in hot rolled, normalized + tempered condition.
DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die steel A514 Gr Q structural steel material is widely used in punching die, cold work forming die, cold drawing die; forming roll, punch; precision stamping die; precision cutting die for wire cutting and punching die for various purposes; difficult to process materials Tools for plastic deformation; cold forging, deep drawing and thread rolling dies; high-speed punching punches, stainless steel punches.
A small amount of Nb is sufficient to obtain excellent comprehensive properties of A514 Gr Q structural steel material etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with A514 Gr Q structural steel material, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.
