Low-tempering Carbon Structure Steel with Titanium Containing High Quality (YB 2009-81)
1 Introduction
The development and application of new materials is essential for the progress of human science and technology. Low-tempering carbon steel with high titanium content is one of the important materials developed in recent years, including carbon structure steel containing titanium (YB 2009-81). The reason why this steel is so popular because of its excellent mechanical properties and low cost.
2 Properties of YB 2009-81
YB 2009-81 is low-tempering carbon structure steel with titanium containing high quality. Compared with ordinary carbon steel, it has superior mechanical properties, such as excellent anti-fatigue property, higher yield strength, higher temperature strength and higher tensile strength, especially its low-temperature strength performance is better than the traditional low-alloying steel. It also has good corrosion resistance. Its corrosion resistance is superior to conventional carbon steel, especially in sour corrosion environment. Its corrosion rate is only 20%-30% of ordinary carbon steel. YB 2009-81 has good weldability and low cold plasticity. The welding process of this steel is similar to that of ordinary carbon steel, and it has high production efficiency and favorable cost performance. The weldability of YB 2009-81 is much better than that of ordinary low alloy steel.
3 Application of YB 2009-81
YB 2009-81 is widely used in many fields. First, it is suitable for the manufacture of boiler drums and collectors, cold boxes, heat exchangers and high pressure containers In chemical engineering. Second, It is also suitable for the manufacture of fire extinguishment pipelines and cryogenic pressure vessels in petroleum, chemical and ship-building industries. Third, it is suitable for the manufacture of high pressure pipelines, pump shells and other components in petrochemical industry and important structural components in large-sized buildings. In addition, YB 2009-81 can also be used in the production of medical equipment, such as surgical instruments and medical apparatus.
4 Conclusion
YB 2009-81 is low-tempering carbon structure steel with titanium containing high quality, which has some advantages in mechanical properties, corrosion resistance and weldability performance. In addition, it has wide application range and low cold plasticity. YB 2009-81 can meet the need of large-scale engineering in terms of quality and economic construction efficiency, and it is an ideal material for the production of oil and chemical plant equipment, ships and buildings.
