What Is The AWG mm Conversion?

American Wire Gauge (AWG) is a standardized wire gauge system used in the United States to denote the diameter of electrical wire. The higher the AWG number, the smaller the wire diameter.

To convert from AWG to millimeters (mm), you can use the following conversion formula:

Diameter (mm) = 0.127mm × 92^((36-AWG)/39)

For example, if you have a wire that is 18 AWG, you can use the above formula to find that it has a diameter of 1.024 mm.

Keep in mind that the above formula is an approximation, as the actual wire diameter may vary slightly depending on the manufacturer and the specific type of wire.

Alternatively, you can find the AWG to mm conversion table online or in electrical reference books.

SS316L Marine Grade Stainless Steel

The corrosion resistance of stainless steel is naturally high, however corrosion can still occur in harsh or aggressive environments, including salt water and marine environments. The resistance of stainless steel can be attributed to the formation of a protective coating of chromium oxide on its surface, protecting the base metal (and, most importantly, the iron present) from moisture exposure and preventing the formation of rust or iron oxide.

Due to the inclusion of molybdenum in their composition, 316 or 316L are the most commonly used stainless steel grades for marine applications. Stainless steels 316 and 304 contain molybdenum, however, it is the relatively high concentration (2.0 to 2.5%) present in these grades that prevent pitting and crevice corrosion caused by salt water. Consequently 316L is a higher cost metal than the equivalent 304 grade.

We have an unrivalled range of 304 grade stainless steel wire too if required.
