Production Methods
1.4529 round bars are manufactured through a precise and controlled process to ensure high quality:
- Raw Material Preparation: High-purity raw materials are selected and prepared for melting1.
- Melting & Casting: The raw materials are melted in an electric arc furnace (EAF) or vacuum induction melting (VIM) process to ensure a homogeneous alloy composition1.
- Hot Rolling: The molten metal is cast into ingots, which are then hot rolled into round bars of the desired diameter1.
- Heat Treatment: The hot-rolled bars undergo solution annealing and quenching to optimize their microstructure and mechanical properties1.
- Finishing: The bars are then sawed, turned, ground, and polished to meet customer specifications1.
