Due to its excellent corrosion resistance, high strength and attractive appearance, stainless steel sees a wide range of uses across both industrial and consumer markets.

The production method of seamless pipe is roughly divided into the cross-rolling method (Mennesmann method) and the extrusion method. The former method is to first perforate the tube with a skew roll, and then extend it with a rolling mill. This method has a fast production speed, but requires higher machinability of the tube blank, and is mainly suitable for the production of carbon steel and low-alloy steel tubes. The latter method is to pierce the tube blank or ingot with a piercing machine, and then extrude it into a steel pipe with an extruder. This method is less efficient than the skew rolling method and is suitable for the production of high-strength alloy steel pipes. Both the skew rolling method and the extrusion method must first heat the tube blank or ingot, and the produced steel tube is called a hot-rolled tube. Steel pipes produced by hot working methods can sometimes be cold worked as needed.

The most well-known legend of the discovery of magnets dates to 4,000 years ago in Northern Greece. According to the legend, a shepherd named Magnes was herding his sheep when suddenly the nails in his shoes and the metal on his staff stuck to the large black rock he was standing on. The curious shepherd dug into the earth and uncovered lodestones, which contain a natural magnetic material we know as magnetite. Lodestones were later named magnetite after Magnes himself.Fast forward to the present day, magnetic materials have become indispensable to modern culture. More than just a refrigerator decoration, they are used in a large array of industrial and medical equipment, exist as components in almost all electronic devices, and have even become their own form of health therapy. In this article, we will look to answer frequently asked questions ranging from “is carbon steel magnetic?” and “which metals are not magnetic?”

Steel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld. The first methods for producing steel pipe were introduced in the early 1800s, and they have steadily evolved into the modern processes we use today. Each year, millions of tons of steel pipe are produced. Its versatility makes it the most often used product produced by the steel industry.
