What is the difference between stainless steel pipes produced by refining furnaces and intermediate frequency furnaces?

Now the stainless steel pipes on the market are generally divided into refining furnace products and intermediate frequency furnace products, so what is the difference between these two?

What is a refining furnace? When the refining furnace is smelting stainless steel, it is necessary to blow oxygen into the molten steel and at the same time blow inert gas argon (Ar) and nitrogen (N2), which will reduce the carbon content in the stainless steel to one. At a very low level, blowing inert gas can also inhibit the oxidation of chromium in stainless steel. The stainless steel produced by the refining furnace has low carbon content, less impurities, and useful elements such as chromium can be well retained. Therefore, the stainless steel tube produced by the refining furnace High ductility, it can well meet the complex stainless steel tube bending, bending, flaring and necking and other processing, less impurities can complete the relatively high precision polishing process.

The intermediate frequency furnace generates a magnetic field through alternating current, and heats the metal in the furnace to make steel. During the steelmaking process, the carbon content cannot be reduced, and the impurities in the metal cannot be removed. The stainless steel pipe made of stainless steel strip produced by the intermediate frequency furnace is extended Poor performance, the stainless steel tube has poor performance in bending, bending, flaring and shrinking. The content of impurities in the stainless steel tube is high, which cannot meet the requirements of fine polishing.

Since the price of the intermediate frequency furnace is lower than that of the refining furnace, there are still a large number of stainless steel pipes for the intermediate frequency furnace in the stainless steel pipe market. There is not much difference on the surface, but we cannot be greedy to buy stainless steel pipes for the intermediate frequency furnace. When buying back to make stainless steel products, it will happen that the stainless steel pipe fails to meet the product requirements.
