Product Overview

Precision-engineered for demanding industrial environments, this SS316L round bar (UNS S31603, EN 10088-3 compliant) delivers exceptional corrosion resistance, high-temperature stability, and superior weldability. As a low-carbon grade stainless steel bar, it minimizes sensitization during welding—making it ideal for critical fabricated components in aggressive chemical, marine, and pharmaceutical settings. Measuring Ø50mm × 6000mm, this 50mm stainless bar is cold-drawn to tight dimensional tolerances (±0.05mm) and supplied in straight lengths with smooth, scale-free surfaces—ready for machining, forging, or precision turning.

Manufactured under strict CE-certified quality control, each batch is traceable with full mill test reports (MTRs) confirming compliance with ASTM A276/A484 and ISO 9001 standards. Its austenitic microstructure ensures non-magnetic properties and outstanding toughness down to cryogenic temperatures—reinforcing its role as a premium-grade corrosion resistant steel solution for global B2B OEMs and job shops.

Key Features

• Ultra-low carbon content (<0.03% C) prevents intergranular corrosion after welding
• Enhanced molybdenum (2.0–3.0%) and chromium (16.5–18.5%) for superior pitting resistance (PREN ≥ 25)
• Cold-drawn finish: Ra ≤ 0.8 µm surface roughness, excellent machinability
• Full CE marking and EN 10204 3.1 material certification included
• Traceable heat numbers and certified MTRs (chemical composition & mechanical properties)

Technical Specifications

Applications

This stainless steel bar is widely deployed across high-integrity sectors: marine propulsion shafts and fasteners; chemical processing valves, flanges, and reactor internals; pharmaceutical equipment components (ASME-BPE compliant); aerospace structural fittings; and nuclear-grade instrumentation parts. Its reliability in chloride-rich environments makes it the preferred choice for offshore platforms, desalination plants, and food-grade conveying systems—where long-term performance of corrosion resistant steel cannot be compromised.
