Stainless steel pegs might all look similar but there are vast differences in their quality and longevity and this is all dependent on the grade of the stainless steel.
201 grade is the cheapest and lowest quality. If you’ve snapped up a pack of cheap stainless steel pegs it’s pretty much assured that they’re made from 201 stainless steel. These pegs will rust over time and must be brought inside after use.
304 grade is the most common kind of stainless steel and is used in a variety of applications, such as kitchen appliances. While it does have some anti-corrosion properties, it does not have the same corrosion resistance as 316 marine grade stainless steel.
316 is the highest quality grade and is ideal for outdoor use and coastal environments. The key difference between 304 and 316 stainless steel is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments.
316 stainless steel contains molybdenum. 304 stainless steel does not.
You can’t tell just by looking at a peg what type of stainless steel it is made from, the only way to know for sure is to test them.
Did you know that Best Pegs are the only stainless steel pegs that are independently tested for quality?
Samples are sent to a NATA accredited laboratory where they are tested by a metals expert (a metallurgist) using an X-ray fluorescence spectroscopy analyser.
X-ray fluorescence spectroscopy is shown to be a rapid and precise method for the determination of elements in stainless steel. For stainless steel to be deemed marine grade 316 it must meet the composition thresholds in the table below:
Below are the results of the most recent test of a selection of Best Pegs, along with a sample (Sample 6) from a large retailer who advertised their stainless steel pegs as marine grade:
As you can see in the final row of the table, they were not marine grade. Don’t get ripped off. Make sure your pegs are the real deal. Only Best Pegs are independently tested to ensure they are made from genuine 316 marine grade stainless steel.
