Steel grade Q345BC is a Polish steel grade manufactured by the Polish steel manufacturer, located in Poland. It is designated by the Polish Institute of Standards (PKN) and is similar to the EN10025-2-2004 European steel standard.
Q345BC steel is a low alloy high strength structural steel, with a minimum yield strength of 345MPa. This steel offers excellent weldability and toughness, making it suitable for a wide range of applications. The Q345BC steel is most commonly used in the automotive, construction, mining and agricultural industries.
Q345BC is composed of three main elements, iron, carbon and manganese. Its tensile strength ranges from 345 MPa to 650 MPa and yield strength from 295 MPa to 540 MPa. The composition of the steel also contains small amounts of chromium and nickel.
Q345BC is an excellent choice for applications requiring high strength at low cost and with good formability. Structures made from Q345BC have superior impact strength compared to conventional steel of a similar grade. It is also resistant to corrosion and abrasion, and can be used in a wide range of temperatures.
Due to its low carbon content, Q345BC is often chosen for welded structures and components. This steel is very ductile and welds well using various welding processes, including TIG, SMAW and FCAW. Furthermore, Q345BC is pre-treated with a zinc coating before welding and is easy to paint, giving it a longer service life.
Compared to other steels, Q345BC is relatively light and also relatively strong. This steel is also very energy-efficient and can thus help to reduce the overall cost of production. The combination of strength and lightweight properties make Q345BC the preferred choice for many applications.
In conclusion, Q345BC is a high-quality steel that offers excellent weldability and strength. It is a great alternative to expensive high-alloy steels, offering superior tensile strength, ductility, corrosion and abrasion resistance, and good formability. The lightweight and low-cost nature of this steel products makes it a great choice for many applications requiring strength and durability.
