Stainless Steel 316L Round Bar

Stainless steel 316l round bar

What is a Stainless Steel 316L Flat Bar/ Hex Bar / Square Bar?

The chemical composition of this material – chromium, nickel, molybdenum, and a minor amount of carbon (0.03%) – is in high industrial demand. A stainless steel 316L flat bar delivers top-of-the-rung corrosion resistance even in pharmaceuticals, ozone generators, and sewage water filters. Its low-carbon profile gets complemented by the addition of manganese and silicon.

These bars can assume shapes such as a square and a DIN 1.4404 hex bar, with client-specified dimensions and processing requirements.

What are the properties and applications of a Stainless Steel 316L Round Bar Flat /Hex /Square Bar?

Top-notch corrosion resistance is deservedly the highlight of 316L stainless steel Round Bars. However, their list of beneficial properties is impressively long:

  • Can endure severe temperatures up to 925 °C
  • Less prone to weld decay
  • A UNS S31603 flat bar requires little maintenance and is easy to clean
  • Suitable for hygienic and sanitary environments

An ASTM A276 SS 316L hex bar and SS 316l circle has immense applications in several sectors, like food processing, brewing, and applications in coastal areas (exposed to high salt concentrations).

What are the different types of metallurgical testing methods used for a Stainless Steel 316L Flat Bar/Hex Bar/Square Bar?

Complete and accurate testing is a must for a SS 316L square bar since it operates in many critical sectors. Metallurgical testing focuses on the microstructure of a specimen under the microscope (magnification up to 500 diameters) and covers the grain size and contamination. It also includes other properties of ASTM A276 UNS S31603 square bars and SS 316l ring, like:

  • Tensile strength
  • Hardness
  • Elasticity

Most manufacturers use spectrometry to confirm the chemical composition and non-destructive approaches like Eddy Current to diagnose defects. Visual inspection of a WNR 1.4404 316l square bar can also be helpful when correct tools, like callipers and micrometres, get used. These tests work in tandem with metallography and grain size/composition analysis.

We ensure precise testing of a UNS S31603 hexagon bar and detail the observations in the Mill Test Report, radiography certificate, and other supporting documents.
