Stainless 303 Product Guide - Online Metals
WEBOverview. The main value of 303 stainless steel is its ease of machining, grinding, and polishing due to the presence of Sulphur in the alloy. However, this slightly does lower the corrosion resistance and toughness of the metal. But despite this, it remains a tough, austenitic stainless steel alloy.
303 vs 304 Stainless Steel: What’s the Difference? - Atlantic Stainless
WEBMay 28, 2020 · Type 303 stainless is a free-cutting material, with the best machinability of any austenitic stainless steel. That said, grade 303 steel is, for the most part, unweldable. Type 304 stainless doesn’t harden with heat treatment and is not a free-cutting material, making it less than ideal for use in machining. However, grade 304 stainless steel ...
303 Stainless Steel (UNS S30300) - Composition, Properties, & Uses
WEBDec 5, 2022 · 303 SS comprises 18% chromium, 8% nickel, and a small amount of manganese, phosphorus, sulfur, silicon, and carbon. This combination of elements makes grade 303 stainless steel highly resistant to corrosion, oxidation, and wear and tear. The higher amounts of chromium also provide superior resistance to high temperatures, so …
WEB303, 303Se. Grade 303 represents the optimum in machinability among the austenitic stainless steels. It is primarily used when production involves extensive machining in automatic screw machines. 303 is also available ex-mill as a "Ugima" Improved Machinability grade, with machinability even higher than that of the standard 303.
AISI 303 (S30300) Stainless Steel - MakeItFrom.com
WEBMay 30, 2020 · AISI 303 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 303 is the AISI designation for this material. S30300 is the UNS number. Additionally, the British Standard (BS) designation is 303S21. It has a moderately low embodied energy among the wrought austenitic stainless steels in the …
303 Stainless Steel: Properties, Composition, and Comparison
WEBAug 5, 2024 · 303 stainless steel is an austenitic stainless steel known for its excellent machinability. It contains about 17-19% chromium, 8-10% nickel, and 0.15-0.35% sulfur, which enhances its ability to be easily cut and shaped. It is commonly used in manufacturing components like screws and bolts where precise machining is crucial. …
AISI 303 Stainless Steel (UNS S30300) | Forging Materials

Stainless Steel Alloy 303 | Product Properties & Composition
WEB303. Stainless steel alloy 303, also known as UNS S30300, is a free-machining variant of the 18-8 austenitic stainless steel family. Its composition includes approximately 18% chromium and 8% nickel, along with the addition of sulfur or selenium to enhance its machinability. Alloy 303 offers good corrosion resistance, making it suitable for ...
Stainless Steel 303 - Grade Summary - Metal Supermarkets
WEBGrade Summary: Stainless Steel 303 is a chromium-nickel stainless steel with added sulfur or selenium and phosphorus to improve machinability and non-seizing properties. It is the most free machining of the chromium-nickel grades, and is non-magnetic in the annealed condition. Typical Applications: Grinding or polishing with good corrosion ...
WEBAlloy 303 is fairly corrosion resistance as compared to other 300 Series Stainless Steel like 304, 316 etc. For better corrosion resistance, Alloy 303 should be used in annealed condition with passivation of parts. Due to Sulphur addition, SS 303 should not be exposed to marine environment resulting in Corrosion Pitting.
