Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a corrosion-resistant and tensile-resistant alloy steel and a production process thereof. Background technique [0002] Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass. The chemical composition of steel can vary greatly. Steel containing only carbon elements is called carbon steel (carbon steel) or ordinary steel; in actual production, steel often contains different alloying elements according to different uses, such as: manganese, Nickel, vanadium, etc. Human beings have a long history of application and research on steel, but until the invention of the Belleville steelmaking method in the 19th century, the production of steel was a high-cost and low-efficiency work. Today, steel has become one of the most used materials in the world due to its low price and reliable performance. It is an indispensable component in co...
