1 1/16 Stainless Steel Hex Bar 316

Product Overview
The ​316 stainless steel hex bar is a high-performance austenitic alloy designed for demanding mechanical and corrosive environments. Renowned for its superior corrosion resistance, durability, and machinability, the ​stainless steel hex bar is ideal for marine, chemical, and industrial applications. Its hexagonal shape provides excellent grip for fasteners, valves, and custom machinery components.

​Technical Specifications

​Mechanical & Physical Properties

​Tensile Strength

The ​316 stainless steel hex bar delivers a ​tensile strength of 580 MPa (84 ksi), ensuring exceptional resistance to deformation under heavy loads. This property makes it suitable for high-stress applications such as marine shafting, chemical valves, and industrial fasteners. Its molybdenum-enriched composition enhances resistance to pitting and crevice corrosion, even in chloride-rich environments.

​Bend Strength

With a ​bend strength of 290 MPa (42 ksi), this alloy maintains structural integrity during fabrication. The hexagonal geometry distributes stress evenly, reducing the risk of cracking during bending or machining. This makes the ​stainless steel hex bar ideal for custom parts requiring tight tolerances and repeatability.

​Identification Marking

Each ​316 stainless steel hex bar is laser-etched with grade identifiers (e.g., “316” or “316L”), batch numbers, and manufacturer codes. This ensures full traceability and compliance with ASTM A276 and ASME SB829 standards.

​Weight Calculation

Calculate the weight of a ​stainless steel hex bar using the formula:
Weight (kg/m) = 0.0068 × (Across Flats in mm)² × Length (m)
Example: A 25mm (1″) hex bar weighs ​4.25 kg/m. This formula helps engineers estimate material costs and structural loads accurately.

​Why Does Stainless Steel Rust?

Although ​316 stainless steel hex bar is highly corrosion-resistant, localized rust may occur under extreme conditions:

1. ​Chloride Exposure: Prolonged contact with seawater, de-icing salts, or bleach can degrade the passive chromium oxide layer, leading to pitting.
2. ​Galvanic Corrosion: Contact with carbon steel, copper, or aluminum in conductive environments (e.g., humid air or saltwater) accelerates corrosion.
3. ​Surface Contamination: Iron particles from tools or handling can embed into the surface, creating rust-prone areas.
4. ​High-Temperature Oxidation: Extended exposure above 400°C (750°F) causes scaling and chromium depletion.

Prevention Tips:

• Clean regularly with pH-neutral detergents.
• Apply passivation treatments (nitric acid) to restore corrosion resistance.
• Avoid abrasive tools and cross-contamination during fabrication.

​Applications

• ​Marine: Propeller shafts, hydraulic fittings, offshore rigging.
• ​Chemical: Valve stems, pump components, reactor parts.
• ​Industrial: Fasteners, tooling shafts, conveyor system parts.
• ​Architectural: Decorative fixtures, custom railings, structural connectors.
