Q215B Carbon Steel Angle Steel
Q215B carbon steel angle steel is a mild steel that can be used without heat treatment. It has good machinability, weldability and plasticity.
This grade is commonly used for welded structures like bridges, factories, ships and other building structures as well as general pipelines for fluid transportation. It can also be cold-formed into a variety of shapes and sizes.
1. Mechanical Properties
The Mechanical properties of Q215B carbon steel angle steel are good, especially its plastic deformation performance. It has good welding and cutting characteristics, can be directly used in the manufacture of load-bearing components Q215B carbon steel angle steel of various structures, such as building beams, reaction towers, lifting and transporting machinery, ships and power transmission equipment. It can also serve as connectors between load-bearing members.
The chemical composition of carbon steel is mainly iron and carbon. It usually contains a small amount of other metals such as silicon, manganese and sulfur. Generally speaking, the higher the carbon content in the steel, the greater its strength and hardness are, but at the same time, it has poorer plasticity than low-carbon steel.
The grades of the carbon structural steel are usually indicated by the first letter S, the second letters H, C and T, and the third letters C or N. The first letter S represents the grade name, the second letter H indicates the hardening condition, the third letter C indicates cold rolling and the fourth letter T indicates tempering or quenching. For example, SPHE represents deep drawing hot rolled steel plate and strip; SPCC indicates general cold rolled steel sheet and strip; and SPCD represents punch carbon steel sheet and strip. Its tensile strength is not higher than 400Mpa. All grades of the carbon structural steel must pass the tensile test and other relevant tests before being supplied to customers.
2. Corrosion Resistance
The corrosion resistance of Q215B carbon steel angle steel is good, and it can withstand the effects of water and chemical corrosion for a long time. This kind of metal is mainly used to manufacture mechanical components, such as gears and shafts, which require high strength. It is also used to make industrial equipment, such as pressure vessels and oil tanks. It can be hot-dip galvanized to improve its corrosion resistance.
Carbon structural steel is one of the most commonly used materials in industry, and it can be rolled into various shapes. It is widely used in bridges, factories, ships and other building structures, and general pipelines for fluid transportation. The structure of the steel is simple, and it requires certain mechanical properties, such as good plastic deformation performance and a certain level of strength.
There are many grades of carbon structural steel, and the most common ones are Q195, Q215, Q235 and Q275. Q195 is low-alloy structural steel, which contains only small amounts of alloying elements. It has a low intensity, but it has excellent plasticity and cold forming performance, welding properties, and corrosion resistance. This grade of steel is usually used for building construction, industrial plants, low and medium pressure boilers, steel containers, and other welded structures. It can be used without heat treatment.
3. Weldability
Q215B carbon steel angle steel has good welding performance and can be used for construction and manufacturing industries. This grade of steel can be welded using both manual and automatic welding machines. It can also be cold formed and machined. The machinability of this type of steel is better than that of mild steel and low carbon steel. It is also able to withstand high loads and stresses, making it suitable for use in engineering structures.
The weldability of this steel is improved by being pickled prior to welding. Pickling is a process where the steel is immersed in an acid solution to remove scale and rust, which allows for more effective welding and improves the quality of the weld. This also increases the corrosion resistance of the weld.
The weldability of this grade of steel is better than that of high-quality low alloy structural steel grades such as Q235 and Q275. This makes it a popular choice for large scale projects, especially those with heavy loads. It is often rolled into round, flat and profiled steel bars, pipes, and sections, including angle steel, channels, beams, and other shapes. It is often used in buildings, bridges, power stations and other large welded constructions. It is also used for less demanding industrial applications, such as tin and aluminum containers, cranes, vehicles, and general pipelines.
4. Formability
Q215B carbon steel angle steel has good formability and welding performance, which makes it suitable for cold forming industry with high strength requirements. It can be used for various kinds of cold forming process, such as rolling, bending, punching and shearing molding technology. It is widely used for building and engineering structures, such as bridges, power transmission towers, lifting and transporting machinery, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation and warehouse shelves.
It is also possible to use it in the Q215 carbon steel pipe fabrication of metal parts, such as wire rod, cold rolled sheet and galvanized steel strip. These steel products can be made by using EPS (Eco Pickled Surface) technology, which uses a liquid mixture of water and abrasive material to mechanically remove the oxide layer formed during hot rolling, without damaging the underlying steel surface.
In addition, carbon steel angle is easy to galvanize, and it has excellent corrosion resistance. This is why it is widely used in construction, transportation and machinery manufacturing. Its good machinability and high heat-resistance make it ideal for a variety of machining applications, including cutting tools and dies. It is also capable of withstanding heavy loads without affecting its low temperature toughness, which makes it an excellent choice for large welded structure. It is the best material for building, shipbuilding and transportation projects.
