asrolled

Asrolled (also written as as-rolled) is a term used in metalworking and materials science to describe a metal product in its original mill condition immediately after undergoing rolling processes, such as hot-rolling or cold-rolling, and before any subsequent heat treatment or mechanical finishing.

In the as-rolled state, the microstructure typically shows elongated grains along the rolling direction, and the material may carry residual stresses introduced by deformation. The surface finish reflects the rolling tools and reductions; imperfections like scale or roll marks may be present depending on the process. Mechanical properties can vary with rolling method: cold-rolled materials are usually harder and stronger due to work hardening but more brittle, while hot-rolled materials tend to be more ductile with a coarser microstructure and lower yield strength.

As-rolled is used as a baseline for further processing. Many applications require annealing to relieve stresses and refine properties, or stress-relieving, normalization, or additional cold-work depending on the target specification and performance requirements.

The term is widely used in specifications, supplier data sheets, and quality control to indicate the starting condition for subsequent processing. Its exact meaning can vary by alloy and production route, so for precise properties engineers refer to material data sheets and process documentation to determine the expected behavior in the as-rolled condition.
