ER 309, ER 309L, and ER 309LSi Stainless Steel TIG Wires are high-quality filler metals used for TIG welding of similar and dissimilar steels. Caliper Overseas is a trusted ER 309, ER 309L and ER 309LSi Stainless Steel TIG Wires manufacturer and supplier, that are used for joining stainless steels to mild or carbon steels. They are composed of chromium, nickel, silicon and manganese that provide strength and corrosion resistance in challenging welding applications.
These TIG wires have high arc stability, low spatter and improved weld bead appearance. Low carbon composition reduces carbide precipitation and therefore intergranular corrosion resistance. The 570 MPa tensile strength, 38% elongation and 410 MPa yield strength make it suitable for industrial and structural use.
