Do stainless steel pegs rust? This is a common question and the answer depends on the following factors.
Most importantly, the grade of the stainless steel is important as not all stainless steels are the same. There are many stainless steel pegs available and they all look the same on the outside so it’s important to determine the grade of the stainless steel before buying stainless steel pegs. Only Best Pegs are independently tested here in Australia to make sure that they’re made with genuine marine grade stainless steel, so you can be assured of quality.
Grade 201 stainless steel is an alloy that contains half the nickel and more manganese and nitrogen than other popular steels. While it is ideal for certain uses, it is not a good choice for structures that may be prone to corrosive forces such as saltwater. This means that if you buy stainless steel pegs in 201 grade stainless steel, they are prone to rusting. The rusty peg pictured on the right is made from 201 stainless steel and became rusty after a period of about four months on the clothesline, we live near the beach and it could not handle the salty air.
Grade 304 is the more common and general purpose type of stainless steel. In fact, this type of stainless steel is so common that it’s likely used in your household appliances. This type is defined by its higher nickel content than other types of stainless steel. Due to the rising cost of nickel, this makes stainless steel grade 304 slightly more expensive than the other types. The nickel, however, is what makes grade 304 less susceptible to corrosion.
While grade 201 has the lowest resistance to corrosion, and grade 304 is more resistant, grade 316 has the most. As you can probably guess, it has the highest nickel content. Obviously, this high nickel content makes grade 316 stainless steel pegs slightly more expensive.
Grade 316 differs from grade 304 in that it has molybdenum, an alloy that fights corrosion. 316 stainless steel is ideal for situations with more saline and chloride exposure so if you live on or near the coast, you need 316 grade stainless steel pegs!
While type 304 stainless steel seems like a more economical choice, it doesn’t have the same resistance to saline and chloride. This will lead it to break down faster, costing you more in the long run when you need to replace it so it makes sense to invest in 316 marine grade stainless steel pegs.
It is still advisable to wash your 316 grade stainless steel pegs every few months (depending on how far you live from the beach/saline environments). This is an easy process of washing in a bucket of soapy water (no chloride cleaning solutions) and drying with a towel.
