GrabPak 316 Stainless Steel TIG Wire (2.4mm) 0.5kg

AWS A5.18 – ER 70S-6

A 0.5kg GrabPak of 316 Stainless Steel TIG welding rods (2.4mm).  316 Stainless TIG wire is the most popular of the stainless TIG rods, having the most corrosion resistance.  Suitable for marine environments where corrosion is a problem as well as in the food industry where hygiene is a risk factor.

Super handy, the grab packs are great for hobbyists needing smaller quantities of rods or for small maintenance jobs when TIG welding aluminium.  Perfect also for site work, these grab packs are supplied in a plastic re-useable tube to keep them dry and undamaged.

316L TIG welding rods are used in a wide range of industries including food processing, dairy and chemical sectors.  This is due to it’s capacity to withstand the effects of intergranular corrosion, which is achieved by having a low carbon content. This wire is ideal for joining applications involving similar types of Stainless Steels.

Additional elements within the chemical composition of 316 TIG Filler wire such as Chromium (Cr) enhances strength, toughness, and wear resistance. The inclusion of Nickel (Ni) provides excellent strength, particularly at high temperatures, plus an impressive strength to weight ratio.  Furthermore, Nickel (Ni) also has good resistance to issues such as hot cracking and distortion.

What is Intergranular Corrosion?

This form of corrosion occurs at high temperatures ranging between 425°C and 850°C.  These temperatures are normally reached during the welding process but can also be the case within high temperature environment operations. As a result of being exposed to such high temperatures a molecular reaction takes place at the grain boundaries.  This reaction occurs between chromium and carbon causing a weakening of the overall structure leading to issues compromising the quality of the finished weld.

For this reason 316L TIG Stainless Steel Filler Wire has a lower carbon content to avoid the possibility of intergranular corrosion becoming an issue.
