SA514 Gr E steel material equivalent GB standard material

The types of carbon steel are basically as the following: SA514 Gr E steel material, Carbon structural steel, which is mainly used in various projects. High-quality carbon structural steel, whose main purpose is for important parts. Carbon tool steel, which is mainly used to make various small tools. Cast carbon steel parts for general engineering, which are mainly used for complex parts that are difficult to form by forging and other methods and require high mechanical properties.

Thin SA514 Gr E steel material steel plate is mainly used in automobile industry, aviation industry, enamel industry, electrical industry, mechanical industry and other departments. The sheets can be delivered directly after rolling, pickled (pickled sheet), galvanized or tin-plated.

The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.

The quenching of steel plate is to heat the SA514 Gr E steel material steel to above the critical temperature, keep it warm for a period of time, and then quickly put it into the quenching agent, so that its temperature drops suddenly, and the speed of rapid cooling is greater than the critical cooling rate, and obtain the heat treatment method of imbalanced structure with martensite as the main body. Quenching increases the strength and hardness of steel, but reduces its plasticity. Quenching commonly used quenching agents are: water, oil, alkaline water and salt solutions.
