Stainless Steel Precision Round Bars

Our precision round bar manufacturing process is designed around one principle: consistent dimensional accuracy at every stage.

Step 1 — Melting & casting. Raw materials are melted in Electric Melting Furnaces and refined using Argon Oxygen Decarburization (AOD) converters. Continuous casting produces billets of controlled composition.

Step 2 — Hot rolling. Billets are rolled on our Bar Hot Rolling Mill (4-stand 460 mm and 6-stand 330 mm lines) to achieve the required profile and size.

Step 3 — Peeling & drawing. Bars undergo centreless bar peeling or cold drawing on our Bar-to-Bar and Coil-to-Coil Drawing Machines and Schumag Combined Polishing & Drawing Machines to achieve close-tolerance diameters.

Step 4 — Straightening. Bars are straightened to achieve straightness up to 0.25 mm/metre TIR.

Step 5 — Grinding & polishing. Centreless grinding and belt polishing achieve surface finish down to Ra 0.2 microns (12 RMS) and 24–320 grit as required.

Step 6 — Inspection. 100% ultrasonic flaw detection (ASTM A-388, EN 10308) and eddy current testing confirm freedom from internal defects. Magnetic Particle Inspection (MPI) checks for surface cracks.

Step 7 — Heat treatment. Where required, bars are annealed, solution annealed, or quenched and tempered in our Heat Treatment Furnaces.

Step 8 — Chamfering & packaging. Both ends are chamfered at 30°–60° via our fully automatic chamfering machine. Bars are then packed with protective distance rings in strong plywood boxes.
