316LSi TIG (GTAW)

ER316LSi Stainless steel GTAW (TIG) welding rod is primarily used to weld low carbon molybdenum-beaing austenitic alloys. The lower carbon content of .03% max. is used to avoid carbide precipitation. The additional silicon content increases the wetting action and yields a smooth bead.

Uniform corrosion occurs in very aggressive environments, typically where many chemicals are manufactured or used, such as in the pulp and paper industry. This is often the case when ER-316LSi Stainless Steel Filler Wires are exposed to acidic or basic solutions. Whether stainless steel corrodes depends on the type and concentration of the acid or base and the temperature of the solution. Uniform corrosion is often easy to avoid with extensive published corrosion data or easily performed corrosion testing in the laboratory.

We as Metalfed Engineering reputed supplier, manufacturer, exporter and trader of SS 316LSI Welding Wire and SS ER-316LSi Filler Wires, which resist attack by phosphoric and nitric acids at room temperature. Acid solutions can be divided into two general categories: reducing acids, such as hydrochloric acid and dilute sulphuric acid, and oxidizing acids, such as nitric acid and concentrated sulphuric acid. Increased chromium and molybdenum content in provides increased resistance to reducing acids, while

Localized corrosion in Alloy ER-316LSi Filler Wires can be difficult to predict as it depends on many factors including chloride ion concentration. Even if the concentration of the chloride solution is known, localized corrosion can still occur unexpectedly. Evaporation and condensation can cause chloride ions to be unevenly concentrated in certain areas, such as in cracks (e.g. under joints) or on surfaces in vapor spaces.
