UNS S30300 (Grade 303) 303 stainless steel bar, also known as UNS S30300 and Grade 303, is considered a free machining stainless steel. 303 stainless steel’s corrosion resistance and great machinability make it one of the most popular free machining stainless steels available. It is used in a wide variety of parts from screw to general machining. Grade 303 does not respond to heat treatment, but the toughness is still excellent as with other austenitic grades.
Chromium is actually the metal behind stainless steel. If a certain amount of chromium is added to steel, it will qualify as stainless steel. One of the best benefits to having stainless steel is that it is so resistant to corrosive action, this is because of the thin protective coating it has from its chromium content. The use of this metal has become a necessity for systems, especially the medical industries. Stainless steel parts and products can be found in cars, airplanes, appliances, kitchens, and factories. Depending on the purpose of the steel, various amounts of nickel, and other metals are used. The steel is often made to be non-heat-treatable or heat-treatable. Various widths, thicknesses and hardness levels are also used. These combinations determine the grade, quality, durability and prices of the steel.
Hot Rolled / Cold Rolled 201/301/304/316/410/430 Stainless Steel Round Bar uses & application: We supply Hot Rolled / Cold Rolled 201/301/304/316/410/430 Stainless Steel Round Bar to Oil & Gas, Refineries,Fertilizers, Heat-Exchangers, Paper & Pulp, Pharmaceuticals, Chemicals,Water Treatment, Dairy, Sugar & Food Processing, Construction, Mining,Shipbuilding, Offshore, Defence, Ports, Railway, Nuclear Power, Power Plant,Cement, Government Org., Engineering Co., Oil Mills, and other industrial projects.
303 Stainless also considered ''free machining stainless'' is for use in automatic machining operations. Corrosion resistant to atmospheric exposures, sterlizing solutions, most organic and many inorganic chemicals.
AISI 303 stainless steel (UNS S30300) was developed for easy cutting and basically belongs to 18-8 stainless steel. It improves the cutting performance while maintaining good mechanical properties. SS 303 has a higher sulfur content, which reduces the resistance on the cutting tool, but has a negative impact on the corrosion resistance, so the corrosion resistance is not as good as AISI 304 stainless steel.
We are well-known providers of superior quality SS Strip, which are highly demanded in the market. Stainless Steel Strip 301 1/2 Hard 1/4 hard and full hard available. These types of stainless steel Strip are various size and shapes. Stainless Steel 301 in hot rolled and cold rolled available..
316 and 316L stainless steels are molybdenum-containing stainless steels. The molybdenum content of 316L stainless steel is slightly higher than that of 316 stainless steel. Because of molybdenum in steel, the overall performance of 316L stainless steel is better than that of 310 and 304 stainless steel. At high temperature, 316 stainless steel has a wide range of uses when the concentration of sulphuric acid is lower than 15% and higher than 85%. 316 stainless steel also has good chloride corrosion performance, so it is usually used in marine environment. The maximum carbon content of 316L stainless steel is 0.03, which can be used in applications where annealing cannot be carried out after welding and maximum corrosion resistance is required.
Alloys 309 and 309S are austenitic chromium-nickel stainless steels that are often used for higher temperature applications. Owing to their high chromium and nickel content, Alloys 309 and 309S are highly corrosion resistant, have exceptional resistance to oxidation, and great heat resistance while offering good strength at room and elevated temperatures. The only significant difference between 309 and 309S is the carbon content, Alloy 309S has a much less carbon composition which minimizes carbide precipitation and improves weldability.
