201 Stainless steel Rod/ Round Bar

Like 304, SS 201 is also in the "Austenitic" group of stainless steels, although it is in a grouping separate from the 300 series: chromium-nickel-manganese grade. 201 is comparable to chromium-nickel types of stainless, including the more common 304 and 301 types. Economy combined with good mechanical and corrosion resistance properties make 201 a very popular grade. It can be formed and welded by common techniques. The primary composition difference between the 201 and 304 Series is a decrease in nickel and an increase in manganese content in the 201. Some of the nickel is substituted with manganese and nitrogen. In general, stainless steel is defined as a steel alloy with a minimum of at least 10% chromium, plus other elements, especially nickel. It is also been referred to as a corrosion-resistant steel (or “CRES”), particularly in the aviation/aerospace industry.

Product Details

Species :According to the production process of stainless steel rod , stainless steel bar can be divided into 3 kinds : hot rolling, forging and cold drawn.

1. The specifications of the hot rolled stainless steel round bar is 5.5 to 250 mm

2. 5.5-25 mm small stainless steel round bar used for reinforcement, bolt, and various mechanical parts

3. More than 25 mm stainless steel round steel, mainly used in the manufacture of mechanical parts and seamless steel tube billet.

Shape: round bar , square bar, flat bar, etc.

Application: hardware appliances, shipbuilding, petrochemical, machinery, medicine, food, electric power, energy, building upholster, nuclear power, aerospace, military industry and other industries!
