What is the value of DIN 17100 St52-3 grade steel yield strength

What is the difference between Q235 steel and Q345 steel? First, strength difference: the lower limit of yield strength of Q235 steel is 235MPA, and the lower limit of yield strength of Q345 steel is 345MPA (Q means "Qu" in Chinese characters, and the later value represents the lower limit of yield strength). Second, the chemical difference: the alloy content of Q235 steel and Q345 steel is different, Q235 steel is ordinary carbon steel, while Q345 steel is low alloy steel DIN 17100 St52-3 grade steel.

Weathering steel plate DIN 17100 St52-3 grade steel for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate DIN 17100 St52-3 grade steel has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.

BBN Group's first blast furnace blast dehumidification system: The project started construction on May 2 and began trial operation on August 28. All data are balanced and stable, blast furnace output indicators have improved significantly, and the daily dehydration capacity of the two blast furnaces is as high as 124 tons, with a daily increase of about 200 tons DIN 17100 St52-3 grade steel, and the blast furnace is running smoothly.

The company is mainly engaged in DIN 17100 St52-3 grade steel steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work DIN 17100 St52-3 grade steel together for a better tomorrow.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
