Spec: Φ20mm × 6000mm
Case: CNC lathe spindle shafts using 316 bright bar are widely used in machinery manufacturing workshops, delivering straightness ≤1 mm/m and machining precision up to IT7 while providing up to three times longer service life than carbon steel shafts.
Spec: Φ50mm × 4000mm
Case: Used in marine aquaculture frame supports installed in shipbuilding yards, passivated 316 black bars demonstrated excellent corrosion resistance and maintained structural stability in seawater environments for more than five years.
Spec: Φ10mm × 3000mm
Case: Reactor bolts made from 316 cold-drawn bar are commonly applied in chemical production workshops</a>, achieving a 98% thread yield rate while maintaining strong resistance to acid and alkali corrosion.
Spec: Φ15mm × 3000mm
Case: Surgical handle rods manufactured from precision-polished 316 stainless steel bars are widely used in medical device manufacturing workshops, featuring surface roughness Ra ≤0.8 μm for easy sterilization and compliance with GB 4806.9-2016 food-contact standards.
