General Characteristics
ER 307 (Sv-08Cr20H9H7T) solid wire and rod for semi-automatic and argon-arc welding provides high quality welds with high oxidation and intergranular corrosion resistance. Widely used in mechanical engineering, food, petrochemical industry and power engineering. It is designed for welding of stainless steels and hard-to-weld steels, welding of austenitic-manganese steels of high strength corrosion-resistant steels, buffer layers with subsequent surfacing of wear-resistant hard layer.

There are 3 types of welding wire. 1) Activated wire (it contains metal and up to 5% of powder additives); 2) solid wire - for welding with semi-automatic and automatic machines; 3) flux-cored wire - for non-fused electrodes. Materials for welding are divided by the method of insulation, modification and a number of other qualities, such as physical characteristics. According to plasticity, the wire is divided into the 1st and 2nd class. Depending on the method of processing - on light and oxidized. The latter is less common. If the wire is damaged, it is not recommended - it may reduce the quality of the weld.
Application of
Cladding hard-welded steel is an inseparable part of any metallurgical production, which is used to connect a variety of metal structures. This wire is used for semi-automatic and argon-arc welding of austenitic-manganese steels with high tensile strength, high-carbon and dissimilar steels working at up to 300°C. It is used for welding semi-automatic single-block welders with a separate wire feeder and 2-block. It is used for welding tanks, pipelines in the chemical, petroleum, food, machinery, when the use of carbon electrodes, which leads to a significant reduction in weld quality.
