Yield strength mpa of Q245R pressure vessel steel sheet sheet structural

Weathering steel is mainly used in railway, vehicles, bridges, towers and other steel structures exposed to the atmosphere for a long time. Q245R pressure vessel steel sheet. Weathering steel is used to make structural parts such as containers, railway vehicles, oil derricks, seaport construction, oil production platform and containers containing hydrogen sulfide corrosion medium in chemical petroleum equipment. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, which benefits the weathering steel component manufacturers and users.

The Q245R pressure vessel steel sheet plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The Q245R pressure vessel steel sheet products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

As the thickness and hardness of Q245R pressure vessel steel sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the Q245R pressure vessel steel sheet from cutting cracks, preheating should be carried out before Q245R pressure vessel steel sheet cutting. Special attention should be paid to preheating to make the entire Q245R pressure vessel steel sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole Q245R pressure vessel steel sheet cannot be preheated, the partial preheating method can be used instead.

The main function of boron in Q245R pressure vessel steel sheet 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.
