Frequently Asked Questions
Q
What is the standard thickness range for hot rolled coils?
Hot rolled coils commonly range from 1.5mm to 25mm in thickness, with width options from 600mm to 2000mm. Custom dimensions can be arranged based on specific project requirements and applicable industry standards such as ASTM, GB/T, or JIS.
Q
What is the difference between hot rolled coils and pickled coils?
Hot rolled coils are produced through high-temperature rolling and typically have an oxide (scale) layer on the surface. Pickled coils are hot rolled coils that have undergone acid treatment to remove the oxide layer, resulting in a cleaner, smoother surface that is better suited for further processing such as cold rolling or coating.
Q
Which material is best for corrosive environments — carbon steel, alloy steel, or stainless steel?
Stainless steel hot coils are the best choice for corrosive environments. They contain chromium and nickel, which provide high corrosion resistance. They are widely used in chemical processing, food production, and medical equipment industries where resistance to rust and chemical exposure is critical.
Q
What tensile and yield strength can I expect from hot rolled coils?
Standard hot rolled coils typically offer a tensile strength between 300MPa and 600MPa, and a yield strength between 200MPa and 400MPa. Alloy steel variants can achieve higher strength values depending on the alloying elements such as manganese and silicon used in the composition.
Q
What industries commonly use hot rolled steel coils?
Hot rolled steel coils are widely used across multiple industries including construction (steel structures, bridges, buildings), automotive (car bodies, chassis, components), machinery manufacturing (equipment and tools), as well as chemical and food processing industries where stainless steel variants are preferred for corrosion-resistant applications.
Q
Can hot rolled coils be customized to meet specific project standards?
Yes. Hot rolled coils can be produced and certified to various international standards including ASTM, GB/T, and JIS. Customization options include specific thickness, width, tensile/yield strength grades, surface treatment (such as pickling and oiling), and material composition.
