Stainless Steel Hydrogen Annealed Wire Size
What is Stainless Steel Hydrogen Annealed Wire Size? It means the dimension of wire, such as diameter, length and so on. Stainless steel welding wire is divided into stainless steel mig, stainless steel tig, lashing wire, spring wire, welding wire, tiny wire, hydrogen annealed wire etc. Common series are 201/309/309L/316L/904L/308LSi and so on.
All stainless steel wire is with good corrosion resistance and general steel grade, heat conduction performance is better than austenitic, thermal fatigue, add a stabilizing element titanium, thermal expansion coefficient is smaller than austenitic, weld parts mechanical performance is good.
Stainless steel hydrogen annealed wire can achieve high-efficiency welding and easy automation of welding. It is widely used in the fields of surfacing and sheet joining. Due to high strength, relatively light weight, especially after the impact, the absorption of energy than other metal materials light, good safety performance, is the use of key materials for the automotive industry.
The chemical composition of hydrogen annealed wire is the same as that of spring wire, but for some stainless steel varieties. This kind of steel has such shortcomings as poor ductility, low ductility and corrosion resistance, which limits its application. Refining technology (AOD or VOD) can be used to make the gap elements such as carbon and nitrogen is greatly reduced, so that this kind of steel is widely used.
The thermal conductivity, low expansion coefficient, good oxidation resistance and anti stress corrosion. The surface tension of the molten metal is reduced, the droplet particles are made finer, and the ejection is more easily realized, so that the arc becomes more stable.
The stainless steel solid wire for submerged arc welding has the same chemical composition as the gas shielded stainless steel wire, but should be equipped with no smelting silicon fluoride or manganese free low silicon high fluorine type smelting flux. At the same time, it can improve the wettability of the molten metal, make the weld bead corrugated beautifully, and it is not easy to produce the lack of penetration, slag inclusion, stomata and other lack of filling.
