This is low alloy steel with alloys of less than 5%. Due to the chemical composition, people also call it chrome-moly alloy.F91 metal has a high strength to withstand high pressure. The low carbon content makes these metals to easy weld. The good corrosion-resistant to the atmosphere, which improves the performance of coatings, makes it is possible to apply in an exposed environment.
These materials are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthroughs, the origins of stainless steel lies in a lucky accident. From the smallest part of the zipper to the largest building skyscraper.
Metal fabrication is widely used across various industrial sectors such as mining, construction, manufacturing, shipbuilding, automotive, aerospace, and energy.
