At the same time of doing well in GL-E32 TM open barge steel plate 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 GL-E32 TM open barge steel plate 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.
API 5L X70 pipeline steel belongs to ultra-low carbon microalloyed steel. The production of API 5L X70 pipeline steel has almost applied all the new technological achievements in the field of metallurgy for more than 20 years. API 5L X70 pipeline steel is a product with high technology content and high added value. API 5L X70 hot rolled GL-E32 TM open barge steel plate high strength pipeline steel is one of the important products in pipeline steel, which requires high precision of hot rolling equipment and difficult process control.
Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the GL-E32 TM open barge steel plate alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the GL-E32 TM open barge steel plate wear-resistant property to meet the requirements of specific working conditions.
Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with GL-E32 TM open barge steel plate, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.
What is the difference between Q345B steel and Q345A steel? GL-E32 TM open barge steel plate, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
