How can I identify genuine Stainless Steel 304H Tubes?
Valour Alloys Inc. explin here the easy trick of identifying genuine Stainless Steel 304H Tubes with several characteristics, testing methods, and certifications. Beginning identifying genuine materials we check the Material Certificate we know as a Mill Test Certificate (MTC) or a Material Test Report (MTR) this repost should mention Material grade 304H, Chemical composition and Mechanical properties Verify that the standards comply with international norms like ASTM A213 or ASTM A312 for SS tubes. Chemical Composition Analysis is one of the important concepts Use a Portable X-ray Fluorescence (XRF) Analyzer or Optical Emission Spectroscopy (OES) to verify Higher carbon content (0.04–0.10%) compared to standard 304 or 304L and Chromium (18–20%) and nickel (8–10.5%) within specified ranges. Mechanical Properties Testing is one type of proof to Confirm higher mechanical strength.
