Weld Star Weldstar ER347 Stainless Steel TIG Filler Wire 5KG

Features and Applications Austenitic stainless steel wire with a significant presence of niobium, that provides resistance to intergranular chromium carbide precipitation, thus increasing the resistance to intergranular corrosion. Increased silicon content promotes weld pool fluidity to give a smooth deposit appearance. Ideal for welding and overlay of chromium-nickel stainless steel base metals of similar composition, stabilised either by Nb or Ti (e.g. types 321 and 347). Typically used on applications for the chemical industry, particularly at high temperatures (e.g. equipment intermittently heated within a temperature range varying from 400°C to 800°C). Including applications such as firewalls, pressure vessels, food processing, dairy, oil and textile industries etc.    Typical Base Materials All 300 series austenitic stainless steel, particularly 321 and 347 (stabilised)* * Illustrative, not exhaustive list   Standards EN ISO 14343-A - W 19 9 Nb Si AWS A5.9 - ER 347Si

Weld Star Weldstar ER316L Stainless Steel TIG Filler Wire 5KG

Features and Applications Austenitic stainless steel wire that has a low carbon content, which reduces the possibilities of intergranular carbide precipitation, while increasing the resistance to intergranular corrosion without the use of stabilisers such as niobium or titanium. The presence of molybdenum provides creep resistance in a halide atmosphere. Ideal for joining and surfacing of stainless steels of similar composition (CrNi and CrNiMo steels/cast steels). Including low-carbon molybdenum-bearing austenitic alloys. Typically used in the food processing, dairy and chemical industries etc.    Typical Base Materials All 300 series austenitic stainless steel, mainly low-carbon molybdenum-bearing* * Illustrative, not exhaustive list   Standards EN ISO 14343-A - W 19 12 3 L AWS A5.9 - ER 316L

Weld Star Weldstar ER317L Stainless Steel TIG Filler Wire 5KG

Features and Applications Austenitic stainless steel wire used for welding alloys of a similar chemical composition. Ideal for severely corrosive environments where crevice and pitting corrosion are of concern. Low carbon content reduces the possibilities of intergranular carbide precipitation. Not suitable for structural service above 400°C or for cryogenic applications. Weld deposit is similar to 316L with high molybdenum content for increased corrosion resistance. Typically used in the chemical and petrochemical industries, marine environments, papermaking and food processing industries etc.    Typical Base Materials Stainless CrNiMo steels e.g. 317L or similar** Illustrative, not exhaustive list   Standards EN ISO 14343-A - W 18 15 3 L AWS A5.9 - ER 317 / 317L   Chemical Composition % (Typical) C% Mn% Si% S% P%     <0.03 1.43 0.45 <0.030 <0.030                   Ni% Cr% Mo% Cu%       13.60 18.82 3.55 <0.75         Mechanical Properties Tensile Strength ≥480 MPa   Yield Strength ≥300 MPa   Elongation ≥25 %   Impact Strength -   Mechanical properties are approximate and may vary based on the heat, shielding gas, welding parameters and other factors.   Shielding Gases EN ISO 14175 - TIG: I1 (Argon)   Welding Positions EN ISO 6947 - PA, PB, PC, PD, PE, PF, PG

Weld Star Weldstar ER309L Stainless Steel TIG Filler Wire 5KG

Features and Applications Austenitic stainless steel wire that has a low carbon content, which reduces the possibilities of intergranular carbide precipitation, while increasing the resistance to intergranular corrosion without the use of stabilisers such as niobium or titanium. Good performance under carburising atmospheres. High temperature oxidation and corrosion resistance. ER 309L can be used to weld dissimilar steels and buffer layers. Ideal for joining and overlay of stainless steels of similar composition, such as AISI 309 castings, and for joining of 3Cr12. Typically used on applications in industrial furnaces and boiler parts, annealing chambers, heat exchangers, fused salt treatment installations etc.    Typical Base Materials All 300 series austenitic stainless steel, 3Cr12, mild steels (cladding)* * Illustrative, not exhaustive list   Standards EN ISO 14343-A - W 23 12 L AWS A5.9 - ER 309L
