316/316L Corrosion Resistant Stainless Steel Hex Bar

316/316L stainless steel hex bar stands up to salt, chemicals, and heavy loads—trusted for marine hardware, chemical processing, and high-stress fittings where failure isn’t an option.

Description

Built for the Tough Jobs – And We Know Tough

We’ve been in the stainless steel game long enough to know that not all hex bars handle real-world conditions the same. When you’re dealing with salt spray, chemical exposure, or high-stress mechanical loads, 316/316L stainless steel hex bar isn’t just a material choice—it’s a reliability statement.

We start with the right chemistry. The 2–3% molybdenum content makes a real difference in resisting pitting and crevice corrosion, especially in chloride-rich environments like coastal installations or offshore platforms. That’s why our 316L variant—with its low carbon content (≤0.03%)—is the go-to for welded components. It reduces the risk of intergranular corrosion after fabrication, which we’ve seen save customers major rework costs in chemical processing plants.

Precision Where It Matters – And Flexibility Where It’s Needed

We machine, cut, and inspect every bar to ASTM A276 and ASME SA479 specs, with tight dimensional tolerances—typically ±0.005” to ±0.010” across the hex flats. That consistency matters when you’re making high-tolerance shafts, valve stems, or custom fasteners. Our in-house grinding and polishing deliver a surface roughness of Ra ≤ 1.6 μm, which not only improves corrosion resistance but also reduces galling during assembly—something our medical device and food processing clients appreciate.

Available in sizes from 6mm to 150mm (1/4” to 6”) across the flats, we stock standard lengths but regularly handle custom cuts from 100mm to 6 meters. Need passivation or pickling? We do that too, right after machining, to ensure the passive oxide layer forms uniformly. Some suppliers skip this step. We don’t.

Mechanically, you’re looking at:
Tensile strength: 485 MPa (70,000 psi) minimum
Yield strength: 170 MPa (25,000 psi) minimum
Hardness: 95 HRB max, balancing strength and machinability

We’ve seen this material hold up in marine rudder systems for over a decade, and in pharmaceutical mixers where cleanability and corrosion resistance are non-negotiable.

Why We’re Different

We’re not just a supplier. We’re a China-based mill with full traceability, from melt source to final inspection. Every batch comes with MTC (mill test certificate), and we support ISO, RoHS, and PED compliance. Whether you need 100 kg or 100 tonnes, we handle it—with custom packaging, labeling, and even OEM-grade documentation.

Need something non-standard? We’ve made hex bars with centerless grinding for bearing applications, or pre-drilled for hydraulic systems. Just tell us what you’re trying to achieve. We’ll help you get there—on time, on spec, and on budget. Reach out. We’re here to listen.
