What is BS 1449 CS4 steel and how to identify its serial number?
BS 1449 CS4 steel is a low carbon steel grade that is used for cold rolled narrow strip. It is supplied in a range of conditions for heat treatment and general engineering purposes. According to BS 1449/1.15-91 standard[^4^], CS4 steel has a maximum carbon content of 0.12%, a maximum silicon content of 0.60%, and a maximum manganese content of 0.60%. It also has a maximum sulfur and phosphorus content of 0.045% each.
The serial number of BS 1449 CS4 steel is a combination of letters and numbers that indicate the manufacturer, the batch number, the thickness, the width, and the condition of the steel strip. The serial number is usually stamped or printed on the edge or surface of the steel strip. For example, a serial number like BSS-1234-0.5-50-A means that the steel strip was produced by BSS Steel Strip[^1^], has a batch number of 1234, a thickness of 0.5 mm, a width of 50 mm, and an annealed condition.
The serial number of BS 1449 CS4 steel can be used to verify the quality and traceability of the steel strip. It can also help to identify the equivalent grades of steel in other standards, such as EN 10132 DC01[^2^]. However, some serial numbers may not match the standard format or may be missing due to wear and tear or human error. In such cases, it may be necessary to contact the manufacturer or supplier for more information or use other methods to determine the properties of the steel strip.
BS 1449 CS4 steel has a wide range of applications in various industries. Some of the typical uses of this steel grade are[^1^] [^2^]:
Automotive components, such as body panels, bumpers, brackets, and hinges.
Domestic appliances, such as refrigerators, washing machines, and dishwashers.
Building materials, such as roofing sheets, cladding panels, and partitions.
Tubes, such as water pipes, gas pipes, and hydraulic pipes.
Shims, spacers, washers, and gaskets.
BS 1449 CS4 steel can be heat treated to improve its mechanical properties and hardness. The standard BS 1449/1.15-91 specifies the conditions for annealing, temper rolling, and skin passing. Annealing is a process of heating and cooling the steel to reduce its internal stresses and increase its ductility. Temper rolling is a process of cold rolling the steel to a specified thickness and hardness. Skin passing is a process of lightly cold rolling the steel to improve its surface finish and flatness.
BS 1449 CS4 steel is one of the many grades of low carbon steel that are available in the market. It has a similar chemical composition to EN 10132 DC01 steel[^2^], which is a European standard for cold rolled low carbon steel strip. However, there may be some differences in the mechanical properties and delivery conditions between the two standards. Therefore, it is important to check the specifications and requirements before using or ordering BS 1449 CS4 steel or its equivalent grades. aa16f39245
