Aug 18, 2023 · 4. 321 Stainless Steel. 321 stainless steel is a grade of stainless steel that is stabilized with titanium (0.4–0.7%). The addition of titanium provides improved weldability, resistance to sensitization, and intergranular corrosion at elevated temperatures.
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International . In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
Oct 23, 2001 · Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized by Titanium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850 °C. Grade 321 is the grade of choice for applications in the temperature ...
Category 2 : Steel specified by chemical composition. In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
The titanium content in SS 321 Stainless Steel helps it prevent carbide precipitation while welding in temperatures ranging between 800 – 1500°F. It also allows the alloy to barely elevated temperatures. Grade 321 stainless steel is highly resistant to oxidation & corrosion and it possesses good creep strength.
May 30, 2020 · AISI 321 (S32100) Stainless Steel. AISI 321 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 321 is the AISI designation for this material. S32100 is the UNS number. Additionally, the British Standard (BS) designation is 321S12. The properties of AISI 321 stainless steel include two common ...
SAE 316L grade stainless steel, sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304/A2 stainless steel. Its primary alloying constituents after iron, are chromium (between 16–18%), nickel (10–12%) and molybdenum (2–3%), with small (<1%) quantities of ...
