Relevance
ER 309 (Sv-07Cr25Ni13) chromium-nickel corrosion-resistant welding wire is designed for semi-automatic welding of dissimilar steels (stainless with low-alloy and non-alloy steels), as well as for welding of stainless austenitic steels. The wire contains: 13% Ni, 24%Cr, and 0.07% carbon. Welding is carried out in argon medium at DC current. This wire is used in mechanical engineering, chemical, petroleum and food industries. Type: ER 309 / W 23 12 L Si / EN 12 072 / AWS A5.9. Analogue of this wire is Св-07Х25Н13.

Application
Corrosion resistant CrNi wire ER 309 (Sv-07Cr25H13) is mainly used for semi-automatic welding. Feeding of ER 309 wire into the weld pool is carried out by a welding semiautomatic machine. There are the following types of semiautomatic welding machines: monoblock with a separate wire feeder and 2-block. They weld various metal products of stainless steel when carbon electrodes are not used, which considerably reduces the quality of the weld. ER 309 stainless steel wire is in demand for semi-automatic and argon-arc welding of austenitic-manganese steels with high tensile strength, high-carbon and dissimilar steels, working at t° up to 300°C.
Advantages
ER 309 is made from high-temperature resistant high-alloyed steel, resistant to corrosion and other aggressive environmental factors and has high strength values. Alloying with Mo, Si excludes fine-crystalline corrosion and gives high quality of the weld.
- Spattering at welding is reduced;
- weld quality improves;
- Consumption of tips decreases;
- the stability of the combustion of the welding arc increases;
- re-ignition of arc is instantaneous;
- low porosity.
Delivery
Sold on D-300 plastic spools, coils, or rods. Each rod is marked and packed in plastic cases, which weigh 5 kg. Three such boxes weigh 15 kg. The surface of welding wire should be absolutely clean and free from scale, rust, grease, oil and other impurities.
