What are Cold Rolled Steel Grades?
Cold rolled steel is actually hot rolled steel that is processed further. After being heated and annealed it is cooled down at room temperature which results in increased strength, improved shape, closer dimensions, and surface finish. It is a bit expensive because the additional process results in increased processing time and labor consequently increasing the cost of production.
Cold rolled steel is used for several applications including structural, furniture, electronics, automobile parts, and construction.
There are several cold rolled steel grades and a few of the most commonly used grades are given below:
This steel grade is produced by using capped, rimmed, or semi-killed steel. This material requires to be coated in order to prevent rust and corrosion. It is available in different shapes such as flats, expanded and perforated sheets, etc. It is used in several applications such as car body, fabrications projects, enclosure, etc.
C1010 is a high carbon content cold rolled steel is produced by using capped, rimmed, or semi-killed steel. This grade of cold-rolled steel is used for manufacturing machine parts that involve bending, drawing at a moderate level, welding and forming. C1010 needs to be coated in order to prevent rust and corrosion. It is hard and has lower strength but its strength can be improved by quenching and tempering. It is available in different types shapes of tubes including round, rectangular, and square. It is used in several applications such as conveyor rollers, handrails, exhaust tubes, handles, display stands, and fabrication projects.
C1018 is a low carbon cold rolled steel. This grade of steel has good machinability, weldability, forming, and fabrication properties. It has higher tensile strength and yield strength as compared to hot-rolled steel. It can be easily welded without performing and pre-heating or post-heating procedures. It is available in several shapes including round, flat, hexagonal, and square. It is used for manufacturing machine parts, due to its high level of workability.
This grade of cold-rolled steel is used for the production of uniform grain structures, and tighter tolerances. It is usually available in tube form. It is used for hydraulic cylinders, machine parts, shafts, etc.
C1045 is a medium carbon cold rolled steel. It has fair weldability and brazing properties because of its medium carbon content. It has good machinability, tensile strength, and yield strength. It is used for several applications like manufacturing machine parts such as shafts, axles, gears, etc.
C1046 is carbon steel that also has sulfur, manganese, and phosphorus. It has good tensile strength, yield strength, thermal conductivity, and hardness.
C1141 is a medium carbon cold rolled steel having manganese and sulfur. It has good strength, machinability, and has better receptibility to heat treatments. It is used in different applications such as the manufacturing of machine parts, aerospace engineering, automotive parts, and many more. It is available in a round bar shape and shaft.
C1144 is a medium carbon cold rolled steel having a high level of strength and hardness. It is good for applications that require wear and stress resistance. Its properties can be enhanced by quenching and tempering. It is an affordable grade as compared to other grades. It is highly recommended for machine parts that need to work constantly and have higher requirements in regards to wear and tear resistance.
