At the same time of doing well in BV DH32 oil tanker steel 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 BV DH32 oil tanker steel 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.
Heat-resistant steel thick plate is made of heat-resistant steel and is processed by hot rolling. According to different structure characteristics, it can be divided into four types: austenitic type, ferrite type, martensite type and precipitation hardening type. BV DH32 oil tanker steel, The heat-resistant steel plate is widely used in the manufacture of petroleum, chemical equipment, boilers, steam turbines, industrial furnaces and other components and other components working at high temperatures.
NM series wear-resistant steel plates have uniform hardness, avoid the local fracture phenomenon caused by uneven hardness. Compared with ordinary steel plate, NM360 steel plate has wear resistance of not less than twice, NM400 steel plate has wear resistance of not less than 2.5 times, and NM550 steel plate has wear resistance of not less than 4 times. The wear-resistant steel plate combines the characteristics of high strength, high hardness, weldability and easy bending.
Chromium molybdenum steel, also known as medium temperature hydrogen resistant steel, refers to the steel added with Cr (≤ 10%), Mo and other alloy elements to significantly improve the high-temperature strength limit and creep limit, and has good hydrogen corrosion resistance and high-temperature resistance performance. BV DH32 oil tanker steel, Chromium molybdenum steel is widely used in oil refining, chemical and other hydrogen containing devices and high-temperature equipment, and is one of the commonly used steels for pressure vessels.
The chemical composition difference between BV DH32 oil tanker steel, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between BV DH32 oil tanker steel, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
