Round Bars
Bright, black, square and hex bars from 5 mm to 350 mm diameter, plus wires from 0.1 mm — in stainless, duplex, nickel alloy, titanium and alloy steel grades.
Product Overview
We stock bar stock for machining, forging and fabrication in a wide grade range: austenitic and martensitic stainless steels, precipitation hardening grades such as 17-4 PH and 15-5 PH, duplex, alloy steel F-grades, and nickel alloys including Inconel, Monel and Hastelloy.
Bars are available in rolled, forged, annealed, pickled, hot rolled and cold rolled condition, with heat treatment available on request. 17-4 PH bars — with roughly 17% chromium and 4% nickel — give an exceptional balance of strength and corrosion resistance, and are widely used in aerospace, automotive and medical equipment.
- Bright bars: 5 mm to 350 mm dia.
- Black bars: 16 mm to 350 mm dia.
- Square bars: 5 mm to 250 mm
- Hex bars: 5 mm to 150 mm
- Wires: 0.1 mm to 5 mm dia.
