- General PropertiesCorrosion ResistanceMechanical PropertiesAlloy 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100). It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 1500°F (427 816°C). The alloy has good oxidation resistance and creep strength to 1500°F (816°C). It also possesses good low temperature toughness.

Engineering FAQ FastenalMy customer is asking for 304 stainless steel. Is this the same as 18-8 stainless steel? 18-8 stainless steel contains approximately 18% chromium and 8% nickel. 304 does fall into this category, but so do a number of other stainless steel grades such as 302, 302HQ, 303, 304L, and XM7. Generally, our hex cap screws meet 304 s/s. The other
Free-machining of stainless steels can be greatly improved by changing the alloying elements within the composition but without drastically changing the basic property characteristics of the material. Some exceptions to the rule can include free-machining grades with high sulfur levels which can lead to a reduction in ductility.

Jan 08, 2002 · In general, austenitic stainless steel grades are difficult to machine. For this reason, fabricators developed a free-machining grade 303 steel. Free-machining versions are also available for martensitic and ferritic grades. Grades 416 and 430F exhibit improved machinability, due to the presence of manganese sulphide that serves as chip breakers. Stainless Steel Types & Myths Austral WrightGrade 304L is used in parts of 4mm and thicker which will be welded but not post weld annealed. Parts made from this grade are generally limited to service at temperatures up to 425ºC. The physical properties and thermal treatments are similar to those of grade 304. Stainless Steel 316, or Grade 316, is known as the marine alloy. Steel Standards - ASTMASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.
