NAS 303AM (SUS 303, UNS S30300) is a high free-machining austenitic stainless steel in which machinability is improved by adding sulfur to Type 304. Although sulfur is an alloying element that reduces corrosion resistance, the corrosion resistance of NAS 303AM is close to that of Type 304 in mildly corrosion atmosphere. Nippon Yakin supplies this product in plate form. 303 Stainless Steel Round Bars Stainless SupplyProduct Description. 303 stainless steel round bar has a lower corrosion resistance, formability and weldability than 304. However, it has optimum machinability among the stainless steels. It should not be exposed to marine environments, because this will result in rapid pitting and corrosion. Uses include nuts, bolts and aircraft fittings/gears.
Sep 19, 2020 · 303 is always used for cases that mainly need smooth cutting and extreme surface finish. It contains selenium, making it easy to cut; on the other hand, 304 is flexible stainless steel, that it does not include selenium. It is commonly used for producing well extensive performance (Moldability and corrosion resistance) material and machine parts. Brass Mechanical Properties E-Z LOKUNS C36000 (free-cutting brass) = 100%. Shear Modulus. 37 GPa Free-Machining of Stainless Steels ::Total Materia ArticleThe chromium, nickel, and sulfur contents of Type 303 are slightly different than that of Type 304, but its physical and mechanical properties are quite similar. Type 303 can be machined at speeds about 25-30 percent faster than Type 304. Type 303 Se is a free-machining vari¬ation of Type 304 that contains selenium instead of sulfur.
May 18, 2005 · The machineable nature of Grade 303 stainless steel is due to the presence of Sulphur in the steels composition. Whilst the Sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. The corrosion resistance of g rade 303 stainless steel is lower than that for 304. Influence of Cutting Environments on Surface Integrity 303 austenitic stainless steel in different cutting environments such as:dry, flood coolant and cryogenic. 2. EXPERIMENTAL PROCEDURE The importance in conducting this experiment is the contribution in the manufacturing field towards the eco-friendly machining of difficult-to-cut materials, through the application of different Overview of 303 Stainless Steel Best Stainless Steel Sep 09, 2020 · Stainless Steel 303 Properties and Uses. Stainless Steel grade 303 has good resistance to mildly corrosive atmospheres (lower than SS304) and good oxidation resistance at temperatures up to 1700°F. Alloy 303 is subject to corrosion cracking in chloride environments above 60, and in the humid marine environment, it is easy to suffer from
Stainless steels are only one segment of the steel spectrum, but they serve a multitude of applications from brightly polished consumer pro- ducts to machinery and Stainless Steel - Grade 303 (UNS S30300)

It is a non-magnetic austenitic stainless steel which is not hardenable by heat treatment. It is the free-machining modification of the basic 18% chromium 8% nickel stainless steel. Sulfur is added to produce the free-machining characteristics. The good mechanical and corrosion-resistant properties of the Stainless 303 - upmet303 is an austenitic free-machining stainless steel. The additional sulfur present in 303 assists in breaking up turnings which reduced drag on the cutting tool. It is used for parts requiring machining, grinding or polishing. 303 is one of the most popular of all the free-machining stainless steels. It offers good strength, corrosion resistance and machinability.
