Introduction

Hot-rolled steel or cold-rolled steel, is a popular product used in a variety of applications. Hot-rolled steel has been hot rolled, aged and cooled, while cold-rolled steel has been processed further and has been hot rolled, re-rolled and then cooled. Hot-rolled steel is more ductile and often used for construction and automotive applications, while cold-rolled steel is often used for precision instruments and machinery.

History

Hot-rolled and cold-rolled steel have been around since the late 19th century. They were first developed as a way to produce very strong and durable steel for construction and industrial applications. Hot-rolled steel was first introduced in Germany in 1877 and in the United States in 1883. It quickly gained popularity due to its versatility, strength and low cost. Hot-rolled steel was extremely popular during the Industrial Revolution and continues to be used for many applications today.

Cold-rolled steel was developed in England in the late 19th century and became popular in the United States after World War II. Cold-rolling steel is more precise and accurate than hot-rolling steel, and produces a tighter grain structure that provides greater strength and rigidity. It is often used for high-precision tools, medical equipment, automobiles and other precision instrumentation.

Types of Hot- and Cold-Rolled Steel

There are two main types of hot-rolled steel—low carbon and high carbon. Low carbon steel is softer and is typically used in applications such as automotive parts and furniture. High carbon steel is harder and is often used to make tools and machines.

Cold-rolled steel can be divided into two categories—ordinary and stainless steel. Ordinary cold-rolled steel is harder than hot-rolled steel and is often used to make tools and machines. Stainless steel is highly resistant to corrosion and is often used for food preparation and high-temperature applications.

Benefits of Hot- and Cold-Rolled Steel

Hot-rolled steel is typically cheaper than cold-rolled steel, which can reduce costs for consumers and manufacturers. It is also easier to form and shape, which makes it great for construction and automotive applications.

Cold-rolled steel is much harder and more precise than hot-rolled steel, which makes it great for precision instruments and machines. It is also much more resistant to corrosion, so it is often used in food preparation and high-temperature applications.

Conclusion

Hot-rolled and cold-rolled steel have both been around for over a century and are widely used today for a variety of applications. Hot-rolled steel is cheaper and easier to form and shape, making it great for construction and automotive applications, while cold-rolled steel is harder and more precise, making it great for precision instruments and machines.

Hot-rolled steel is steel rolled into a certain thickness at a high temperature. This hot-rolling process allows steel to reach higher strength requirements than cold-rolling. Hot-rolled steel is mainly used in construction, automobile manufacturing, bridges and general steel structures. It is characterized by having a high surface hardness and excellent mechanical properties.

Hot-rolled steel is typically divided into five grades, depending on its thickness, type, structural requirements and application. These grades are A (the highest strength grade of steel), B, C, D and E. Depending on the grade, hot rolled steel can be up to 100,000 pounds per square inch (PSI) stronger than cold rolled steel.

With the ultra-high strength provided by hot-rolled steel, many advantages have been realized in applications such as bridge structures, high-rises, and seismic structures, which make extensive use of hot-rolled steel. Hot-rolled steel has also been used many times for building components with weight-bearing capability, such as aircraft fuselages and space frames.

In mechanical processing and other production processes, hot-rolled steel is used in various welding and cutting processes, including brazing, carburizing, wire cutting, and so on.

In addition to the high strength provided by hot-rolled steel, the quality assurance is also reliable. Through quality assurance, the specifications of steel can be ensured, and the performance characteristics of steel can be greatly improved. These characteristics not only reduce the cost, but also maximize the efficiency.
