Hot Rolled Commercial Steel Coil
Hot rolled commercial steel coil has been processed at high temperatures and is suitable for general use in a variety of applications such as construction, automotive, and manufacturing. The process of hot rolling involves passing the steel through rollers at high temperatures, which results in a material with a rougher surface texture but improved mechanical properties. Commercial Hot-Rolled steel is also known as low-carbon steel and is commonly used for mild forming and bending.
There are four Hot-Rolled Commercial Steel grades- CS Type A, B, C, or D. Each type has distinct chemistries that have been developed for specific applications. The most common grade of commercial steel is CS Type B. Reach out to our experts today and we will be glad to help you select the exact grade for your hot rolled commercial steel coils.
- Recommended for: Unexposed applications where surface smoothness is not important
- Chemistry: A ‘plain’ steel without expensive alloying elements.
- Cost: Low
Commercial Steel Types
CS Type A
CS Type A steel is a versatile grade known for its excellent formability and weldability. It is typically low in carbon content and relatively soft, making it suitable for a wide range of fabrication processes such as bending, stamping, and deep drawing. CS Type A is commonly used in the manufacturing of automotive components, appliances, furniture, and construction materials.
CS Type B
CS Type B steel is similar to Type A but has slightly higher carbon content and may exhibit slightly greater strength and hardness. This increased strength makes it suitable for applications requiring moderate to high strength and stiffness, such as structural components, machinery parts, and agricultural equipment. CS Type B is also well-suited for welding and forming processes.
CS Type C
CS Type C steel is characterized by higher carbon content and increased strength compared to Type A and B. It offers excellent strength and hardness properties, making it suitable for applications requiring greater structural integrity and load-bearing capacity. CS Type C is commonly used in construction, industrial equipment, and structural components where strength and durability are paramount.
CS Type D
CS Type D steel is the strongest and hardest among the CS grades due to its higher carbon content and heat treatment. It exhibits superior strength, hardness, and abrasion resistance, making it suitable for demanding applications such as heavy-duty machinery, agricultural implements, and wear-resistant components. CS Type D is less formable compared to other grades but offers exceptional strength properties.

FAQs
What are the benefits of hot rolled commercial steel?
The greatest benefit of hot rolled commercial steel is its low cost. Additionally, it is more weldable and ductile when compared to higher carbon steel grades.
What is steel grade CS Type B?
CS Type B (also known as Commercial Steel Type B) is the most common form of commercial steel. It is designated by chemical requirements, not mechanical properties, with a slightly higher max range of carbon content (0.15%) than other types. Both hot rolled and cold rolled steel can be produced as CS Type B.
What is CS Type B most used for?
CS Type B is mostly used in flat applications or mild formed parts with no surface requirements. It is often used by stamping fabricators, tube manufactures, and roll forming applications in the automotive, energy, and agricultural industries.
What is Commercial Hot Rolled Pickled & Oiled (HRPO+)?
Commercial hot rolled pickled and oiled (HRPO) steel is a type of steel that has undergone further processing after being hot rolled. The pickling process involves removing any surface oxides, scale, or other impurities that may have formed on the steel during hot rolling using an acid solution. After pickling, the steel is then oiled to help prevent rust and improve its surface finish.
