201 Stainless Steel Round Bar: Characteristics, Composition and Multiple Applications
201 Stainless Steel Round Bar Concept
201 stainless steel round bar, a type of 200 series stainless steel, is a chromium-nickel-manganese stainless steel material with an austenitic structure. Its cross section is round and its surface is smooth. It has the characteristics of acid and alkali resistance, as well as high density, polishing without bubbles and pinholes.201 Stainless Steel Round Bar Features
Corrosion resistance: 201 stainless steel round bar shows good corrosion resistance in a variety of corrosive environments and can resist the erosion of a variety of acids, alkalis, salts and other chemical substances.Mechanical properties: It has high strength and hardness, while maintaining a certain toughness and ductility, and can withstand large external forces without deformation or fracture.
Processing performance: It is easy to process and form, and can be made into round bars of different specifications and shapes through various production processes such as hot rolling, forging, and cold drawing.Polishing performance: The surface finish is high after polishing, without bubbles or pinholes, and is suitable for making products with high requirements for surface finish.
Chemical composition of 201 stainless steel round barThe chemical composition of 201 stainless steel round bar mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), nickel (Ni) and nitrogen (N), and the specific contents are as follows:
Element Content range (%)C (carbon) ≤0.15
Si (silicon) ≤0.75 (or ≤1.00, depending on the specific standard)Mn (manganese) 5.50~7.50
P (phosphorus) ≤0.060S (sulfur) ≤0.030
Cr (chromium) 16.00~18.00Ni (nickel) 3.50~5.50
N (nitrogen) ≤0.25Application range of 201 stainless steel round bar
Architectural decoration: 201 stainless steel round bar is often used to make various architectural decorations, such as stainless steel railings, handrails, curtain walls, etc., due to its beautiful appearance and good corrosion resistance.Auto parts: In the automobile manufacturing industry, 201 stainless steel round bars are used to manufacture auto parts, such as automobile mufflers, valve bodies, etc., which can meet the requirements of lightweight, high strength and corrosion resistance of automobiles.
Mechanical manufacturing: In the field of mechanical manufacturing, 201 stainless steel round bars are widely used in the manufacture of various mechanical equipment and parts due to their good mechanical properties and processing properties.Other fields: In addition, 201 stainless steel round bars can also be used to make various watch cases, watch strap bottom covers and other high-quality materials, as well as industrial pipes, decorative pipes, etc.
