Hot-rolled (HR) coil of stainless steel refers to stainless steel that has been processed through
a hot rolling mill at high temperatures, typically above 1700°F (926°C). This process involves
passing the steel through large rollers to shape it into coils, making it easier to handle and
transport. During hot rolling, the steel is softened, which allows it to be shaped into various
forms such as plates, sheets, or coils. Hot-rolled stainless steel retains a rough surface finish
and may exhibit scale or oxidation due to the high temperature during processing.
This type of stainless steel is commonly used for applications where surface finish is not as critical, but
strength and durability are important. Hot-rolled stainless steel coils are widely used in industries such
as construction, automotive, and manufacturing for components that do not require a polished appearance but
need good structural integrity.
