How to Identify Quality Stainless Steel 316/316L Tubing
Valour Alloy Inc., we carry a full inventory of Stainless Steel 316 / 316L Tube Both products belong to the austenitic family, known for excellent corrosion resistance, especially against chlorides and marine environments.
There are many points we can identify regarding the Quality of Stainless Steel 316 & 316L Tubes before purchasing products, we believe that Proper Certifications like Material Test Certificates (MTC) its prof of genuine material used for the manufacturing of SS 316 & 316L tubes Ensure the tubing comes with an EN 10204 3.1 or 3.2 certificate, detailing chemical composition and mechanical properties with Standards Compliance like ASTM A213, A269, or A312. Verification of chemical composition is one of the important concepts identified for the Quality of Stainless Steel 316 & 316L Tubes using the Positive Material Identification (PMI) device to verify the chemical composition.
Chromium (Cr): 16-18%
Nickel (Ni): 10-14%
Molybdenum (Mo): 2-3% (important for corrosion resistance)
Carbon (C): 316: Up to 0.08% & 316L: Up to 0.03%
After the PMI, we conduct the mechanical testing as Tensile & Yield Strength Tests for the conformation mechanical strength requirements Hardness Tests Verify the hardness falls within standard ranges to ensure proper ductility and strength balance.
