Q215B Carbon Steel Angle Steel
Q215B carbon steel angle steel is a kind of carbon structural steel with high strength and good plasticity. It can be quenched and hardened, and it is also characterized by high welding performance. It is widely used in bridges, factories, ships and other building structures, and general pipelines for fluid transportation.
Characteristics
Q215B carbon steel angle steel is a type of cold rolled low-carbon structural steel. It has a good performance and high quality. Its yield point is lower than that of Q235 and has a higher hardness. It is easy to machince and has good plasticity, cutting and welding performance. It also has a high red hardness and wear resistance. It can be used to manufacture mechanical parts with higher requirements for hardness and toughness, such as gears and shafts.
It is smelted by converter or open hearth furnace, with the main raw materials being molten iron and scrap steel. The sulfur and phosphorus content in the steel is usually less than 0.5%. The addition of alloying elements such as chromium, manganese, cobalt and vanadium can improve its strength, hardness and tensile toughness.

It can also be used for welded structural parts with high quality requirements, such as those found in construction and bridge engineering.
Applications
Steel angle bars (also known as angular bar) are used in a wide range of construction and engineering applications. These include building workshops, high-voltage transmission towers, bridges, and vehicles. The use of steel angle bars can increase the strength and stability of structures, making them more resistant to external forces, such as strong winds and earthquakes.
Q215B carbon steel is a common material in the construction industry. It is a low-alloy, high-strength steel with good ductility and durability. It is also used in many manufacturing processes, such as cutting and welding. In addition, it can be forged into shapes with high accuracy.
The cold rolled equal leg angle steel produced by our factory is a high-quality, durable product that can be cut, welded, bent and processed according to customer needs. It has a fixed thickness and width, which can not only save the cost of processing but also reduce waste and materials consumption.
The EPS (Eco Pickled Surface) process is a highly effective way to remove the oxide layer formed on flat rolled carbon steel during hot rolling. This innovative technology uses a unique “slurry blast” process, where a mixture of carrier liquid and abrasive material is impinged against the surface of the steel strip. The abrasive particles disperse and remove the oxide layer, leaving the steel clean and ready for further processing.
Production process
The manufacturing process for steel angles and channels is an intricate journey that transforms raw materials into essential components in construction, manufacturing, and engineering. These load-bearing structural shapes require careful selection of raw materials, then undergo a rigorous process of heating, shaping, cooling, and finishing. The result is a robust, reliable metal profile that contributes to the strength and stability of structures across numerous industries.
The production of angle steel begins with the selection of raw materials, which are then heated in specialized furnaces until they reach a malleable state. The molten metal is then formed into long strips known as billets, which are then fed into a rolling mill. During galvanized steel coil this hot rolling process, the billets are subjected to significant pressure that elongates and aligns the metal grains, increasing its mechanical properties.
Once the billets have been rolled into their final shapes, they are allowed to cool. Then, saws or shearing machines cut them into specific lengths. Finally, the profiles are subjected to a range of finishing processes to enhance their corrosion resistance and appearance.
For example, Q215B carbon steel angle steel is coated in a galvanizing solution that acts as a protective layer against corrosion and improves its surface aesthetics. It is also commonly refinished with a powder coating, which enhances its durability and provides an additional layer of protection against corrosion.
Packaging
Q215B carbon steel angle steel is widely used in load-bearing components for building structures and general pipelines for fluid transportation. It has high strength and stability, and can withstand external forces such as strong winds or earthquakes. Moreover, it is easy to cut and weld. It is also used in the manufacture of mechanical parts, such as shafts, connecting rods, bolts and wheel gears.
It is usually smelted by converter or open hearth furnace, and the main raw materials are molten iron and scrap steel. The sulfur and phosphorus content of this product is lower than that of high-quality carbon structural steel. The sulfur content should not be higher than 0.050%, and the phosphorus content should not exceed 0.045%.
Carbon steel angle steel has certain elongation and strength, good toughness and castability. It is suitable for use in heavy items such as bridges, factories and ships. It is also often found in lighter items, such as furniture and home appliances.
It is mainly used in the following fields:
