STAINLESS STEELS – Austenitic stainless steels | |
| Austenitic stainless steels are presented in the ASME Boiler and Pressure Vessel Code with two sets of allowable stresses. The reason for this is their relatively low yield strength. The higher allowable stress values were determined at temperatures where the usage would be restricted by the short-time tensile properties. The higher stresses exceed 62-1/2%, but do not exceed 90% of the yield strength. At these stresses, small amounts of plastic deformation can be expected. These higher stress values are usually used for super-heater and reheater tubing. | |
| The Boiler Code lists maximum allowable stresses for varying temperatures depending on the individual austenitic stainless grade. | |
SA213-T304 | Variations of this 18 chromium, 8 nickel grade include 304L, 304LN, 304H and 304N. Each of these offers excellent corrosion and oxidation resistance along with high strength. |
| High strengths are maintained in the low carbon grades by controlling the nitrogen content. | |
| T304 has higher carbon and a minimum solution annealing temperature to assure good long-time elevated temperature strengths. T304 grades are limited to 1650F under oxidizing conditions. Section I of the ASME Boiler Code lists allowable stresses up to 1500F. | |
SA213-T316 | T316 is similar to T304, but offers better corrosion resistance and creep strength. The molybdenum addition to 316 increases its resistance to pitting and crevice corrosion. Variations of this grade include 316L, 316LN, 316H and 316N. |
SA213-T321 | T321 and 347 are variations of T304 and have comparable minimum tensile properties. These two grades are stabilized with additions of titanium and columbian respectively, along with proper heat treatment. To insure good long-time strength at elevated temperatures, T321H and 347H-like 304H-were developed with higher carbon contents and specified minimum solution annealing temperatures. |
| Of all the stainless steels, T309 (25 chromium, 13 nickel) and T310 (25 chromium, 20 nickel) offer the maximum resistance to oxidation and corrosion. They also offer good high-temperature properties. Since these steels contain ferrite, however, they are more susceptible to sigma phase. | |
