high temperature 304 stainless steel
May 13, 2019 · As part of the five families of stainless steel, 304 stainless steel and 316 stainless steel are austenitic grades that contain high levels of chromium and nickel. This has the following impact: Chromium Increases tensile strength, hardness, hardenability, toughness resistance to wear and abrasion, resistance to corrosion and scaling at elevated temperatures. Composition/Properties SSINAStainless steels are used at temperatures up to 1700° F for 304 and 316 and up to 2000 F for the high temperature stainless grade 309 (S) and up to 2100° F for 310 (S). Stainless steel is used extensively in heat exchangers, super-heaters, boilers, feed water heaters, valves and main steam lines as well as aircraft and aerospace applications.
temperature or at intermittently high temperature. For a prolonged service life, such as 20 years, plain carbon steels are usually limited to a maximum operating temperature of 750°F (399°C); the ½% molybdenum alloy steels to approximately 850°F (454°C); and the stainless steels to considerably higher temperatures depending upon the type High Temperature Properties - hghoustonGeneral Information on High Temperature Properties:Allowable stresses for austenitic (300 series) stainless steel unfired pressure vessels are found in Section VIII of the ASME Boiler Code, table UHA-23. Additional information on high temperature properties can also be found in the ASM Metals Handbook, Volume 3, 10th Edition.

Dec 14, 2019 · AISI 304 Grade Stainless Steel (UNS S30400) AISI 304 stainless steel (UNS S30400) is the most commonly used material in stainless steels, and is usually purchased in an annealed or cold worked state. Because SS 304 contains 18% chromium (Cr) and 8% nickel (Ni), its also known as 18/8 stainless steel.Type 304 has good processability, weldability, corrosion resistance, heat resistance, What is Stainless Steel 304, 304L, 304H? - IntametIt resists oxidisation in continuous use up to 925 o and in intermittent use to 870 o. However, using it in a temperature range between 425 o and 860 o can result in carbide precipitation and subsequently intergranular corrosion. 304L, with its lower carbon content, is less prone to carbide precipitation and can be used at these temperatures. 304H has greater strength at high temperatures and may be the steel Zinc treatment effects on corrosion behavior of 304 Sep 01, 2006 · Corrosion specimens of type 304 stainless steel (UNS S30400) were exposed at 260 °C in a flowing autoclave facility (10 cm 3 min 1) comprised of a 1 l, type 347 stainless steel (UNS S34700) vessel, and fed from stainless steel tanks containing deionized, hydrogen-sparged water.
