15Mo3 steel is a kind of pearlitic heat-resistant steel, which can still show its characteristics under high temperature and long time load. 15Mo3 steel is used for heating surface of A131 DH40 oil platform steel plate low and medium pressure boiler (working pressure is generally not more than 5.88MPA, and working temperature is below 450 ℃). 15Mo3 steel is widely used in petroleum, chemical industry, power station, boiler and other industries. 15Mo3 steel is used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, etc.
Steel can be divided into ordinary steel and special steel, which is an important symbol of a country's steel production level. The special steel includes spring steel, round steel, die steel, heat-resistant steel, wear-resistant steel, bearing steel and so on. Compared with ordinary steel, the A131 DH40 oil platform steel plate special steel has better physical properties, higher strength, stronger compressive strength and better accuracy. At the same time, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance.
Try to use A131 DH40 oil platform steel plate high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the A131 DH40 oil platform steel plate temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
We are engaged in A131 DH40 oil platform steel plate corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, A131 DH40 oil platform steel plate ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.
After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service.
