Cold rolling flattens the grains of steel, resulting in harder, less ductile material. The annealing process softens the steel by reshaping grains to their prior circular shape. Steel is annealed in atmospheres that protect the steel from oxygen, heated to a specified temperature, held for a specified length of time, and cooled.
Steel hydrogen annealing softens metals, and simultaneously changes the properties of the metal, allowing for further processing and an overall cleaner product. The resulting microstructure also makes it easier to stamp parts. Other benefits of hydrogen annealing include:
Worthington Steel was one of the first independent steel processors to offer hydrogen annealing, and we continue to lead with our expertise and materials support. We use high convection bases to drive heat into the coils at an equal rate. Material is heated and held at a specific temperature followed by a controlled cooling process. Collaborate with our Materials Support team to decide how and when to use annealing for your project.
