p265gh steel application and heat treatment

12Cr1MoV alloy plate is widely used in superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power plant boiler. At 580 ℃, 12Cr1MoV alloy plate still has high thermal strength, oxidation resistance and high endurance plasticity. The production process of P265GH steel and 12Cr1MoV alloy plate is simple and the welding performance is good, but it is sensitive to the normalizing cooling rate. Pearlite spheroidization will occur after long-term use of 12Cr1MoV alloy plate at 580 ℃.

With the development of China's p265gh steel market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of p265gh steel products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This p265gh steel method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.

The main function of boron in p265gh steel and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
