Normalized steel bar is produced by normalizing which is one kind of heat treatment to get even microstructure and better mechanical properties and hardness. Our advantages and more services of normalized steel bar includes:
1) Wide range of diameters from 10mm to 100mm
2) Customized Length from 100mm to 12000mm
3) Good surface roughness: 0.4um to 1.5um
4) Good straightness: 0.5mm/m to 2mm/m
5) Good roundness: 80% of diameter tolerance
6) Diameter tolerance: -0.02mm to -0.06mm/h9, h10, h11
7) Matched further processing: Grinding, polishing, straightening
8) Anti-rusty package
9) Full sets of testing equipment: Surface, Dimenstion. Mechanical properties testing
10) Fast delivery time
