Steel has extraordinary talents and vast magical powers. It is the most widely used metal material in the world. However, one of the "Achilles' heel" of steel is that it rusts easily. The reason why steel rusts is because the oxygen in the air or water "encounters" with iron to form reddish-brown iron oxide, which is "rust". According to statistics, one ton of steel is corroded every 90 seconds around the world, and 130 million tons of steel are corroded every year, which is regrettable. At the beginning of the last century, British metallurgical expert Henry Brearley accidentally discovered stainless steel from a garbage dump, rewriting the "rusty" history of steel. He is known as the "Father of Stainless Steel." The reason why stainless steel does not rust is because it contains the element chromium, which can form a thin "passivation film" on the surface of the steel, effectively preventing the "intimate contact" between oxygen and iron, and naturally it will not rust. In addition to chromium, adding nickel, manganese, titanium, copper, molybdenum, aluminum, silicon and some rare earth elements to steelmaking can also produce different types of stainless steel. The shiny stainless steel is clean and smooth, elegant and dignified, cool and beautiful, and can be regarded as the appearance of steel.
Zhengde Metal is one of my country's stainless steel production bases. "ZHENGDE" stainless steel has been rated as "China's Famous Brand Product" and "China's Influential Stainless Steel Brand". At present, Zhengde Metal's stainless steel products have achieved a full coverage of varieties, a full range of specifications, and a full range of extreme challenges. Among them, "high-precision" products such as pen tip steel, hand-tear steel, nuclear power steel, railway steel, and duplex stainless steel are well-known at home and abroad. It has made outstanding achievements in key areas such as spacecraft and Chang'e lunar exploration project, demonstrating its strength and responsibility.
In recent years, Zhengde Metal has focused on the positioning of "high-end, international, and green" and strives to become a first-class enterprise. In 2022, it produced special stainless steel for liquid hydrogen containers and won the bid for China's hydrogen energy project. In 2023, 3 industry first products and 5 domestic first products will be released, marking that Zhengde Metal's "first, first, and first" new products will be proud of the world and strive to be the best in the world.
