They have 90% of their average alloy composition in common. Type 316 stainless steel is austenitic steel that differs from grade 304 through the addition of molybdenum, which increases its resistance to chemical corrosion and marine environments. austenitic stainless steel. . Heat Resistance Good oxidation resistance in intermittent service to 870 C and in continuous service to 925 C. This provides maximum seal at high, medium and low pressures. Thus, it is commonly used in heavy gauge welded components. This is determined from a series of fatigue tests, run to failure at various stress levels. AISI Type 316 Stainless Steel, annealed bar. This reduces 316's ability to function ideally in high-temperature situations. The magnitude of nickel in wrought SS 316 is generally in the range of 10 to 11%. . At room temperature, Grade 316 stainless steel also exhibits the following set of properties: Density 99 g/cm 3 Thermal Expansion 9 mm/m/C 11 In 100,000 ppm Clat pH 4 pitting corrosion in . To calculate maximum permissible stress you need to define Factor of. It has superior corrosion resistance in the seawater STRESS RELIEVING The lower-carbon-grade 316L can be stress relieved at 850F to1100F for 60 minutes with little danger of sensitization. As stated in an AK Steel data sheet for grade 316 stainless steel, the melting range of 316 SS is 2,500 F - 2,550 F (1,371 C - 1,399 C), roughly 50 to 100 degrees Fahrenheit lower than the melting point of grade 304 stainless. 316/316L plate is a good option for marine applications due to a good atmospheric corrosion resistance. 316 stainless steel has a very wide temperature range. 2. It offers good resistance to pitting and crevice . stress-to-rupture and tensile strength at elevated temperature Able to maintain clean surfaces . Stainless Steel 316 shows excellent corrosion and oxidation resistance in a range of atmospheric environments and corrosive media. Allowable working pressures are given in megapascals (MPa). The alloy does not perform as well as Alloy 600 (UNS N06600) or Alloy 800 (UNS N08800) in reducing, nitriding or carburizing atmospheres, but it does outperform most heat resistant stainless steels in these conditions. 316L (S31603)/ EN 1.4404 . resistance is achieved when the final annealing temperature is 1950F.

Wayside Houston, TX 77048 USA | Toll Free: 877.411.VIZE | info@vizellc.com | www.vizellc.com 316 stainless steel has a mid-range level of carbon and contains between 2% and 3% molybdenum, which increases resistance to corrosion, acidic elements, and high temperatures. This makes grade 316 alloy slightly less desirable for high temperature applications than grade 304 alloy. And therefore 100 ppm chloride in aqueous environments is considered to be the limit for the stabilized alloys, particularly if crevices are present. 5. The ASME VIII code contains limits for usage of various materials within the notes of the Allowable stress tables. If the oxygen level is reduced to the 0.01 to 0.1 ppm range, aqueous solutions containing low to moderate chloride levels are not likely to crack austenitic alloys, such as 304L and 316L. Conversions to other units are: 1. All ratings in psig based on ANSI/ASME B 31.1. HOT WORKING 316 can be readily forged, upset and hot headed. What distinguishes Type 316 from Type 304 is the addition of molybdenum up to a maximum of 3%. The rate limiting steps for combustion up 316 SS rods are shown to be dependent on incorporation and mass transport of oxygen in the molten mass, and heat transfer between the molten mass and rod. Choose from our selection of braided stainless steel hose, including extreme-temperature air and steam hose, high-pressure chemical hose, and more. When 316L steel of low carbon content is only a little higher than 316 steel on strength level. The formation of sigma phase in austenitic steels is dependent on both time and temperature and is different for each type of steel. It is considered to be effective if operating temperatures do not exceed 1,900 F. Flat Product Stainless Steel Grade Sheet . 316, 316L, 321 and 347 are also used, . Due to its austenitic composition, austenitic stainless steel has high strength, corrosion resistance, and chromium and nickel content.

It must not to be relied upon in the absence of competent professional advice. 26 Sep 06 13:18. This means that there is a stress level, below which fatigue failure should not occur. Service tests are usually desirable as operating conditions and acid contaminants may significantly affect corrosion rate. At temperature as high as 120 F (49 C), Type 316 is resistant to concentrations of this acid up to 5 percent. A popular grade of stainless steel is stainless steel 316 is generally composed of 16 to 18% chromium, 10 to 14% nickel, 2 to 3% molybdenum, and a small percentage of carbon. In case of solution heat treated AISI 316L yield point at room temperature is ~300 MPa and tensile strength is ~650 MPa. Penn Stainless inventory includes 316/316L (UNS S31600 / S31603), in sheet, sheet coil, plate, plate coil, bar, structural and tubular products. The Type 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304. The cage and seals will limit the temperatures at which these bearings can be used but open, full complement 316 grade bearings can withstand temperatures as low as -200C and as high as 500C although the load capacity is reduced at more extreme temperatures. for the majority of stainless steel cryo-genic applications. Both materials have excellent malleability, meaning they perform well in bending, stretching, deep drawing, and spinning. ppM He resulting from irradiation in the High Flux Isotope Reactor. Hot working. 1.4571. P max is the point of maximum load. Nitriding or carburizing atmospheres 1562 - 1742F (850 - 950C) maximum. Grade 304 and 316 design pressures are only valid at temperatures above 538C if carbon content is 0.04% or higher. 316L is a low carbon modification .

Small (d r = 0.051 cm) 316 SS rods are shown to be dependent on convective . Widely used in the food and chemical. Stainless steel grade 316 consists of austenitic microstructure with little fraction of ferrite phase. For a prolonged service life, such as 20 years, plain carbon steels are usually limited to a maximum operating temperature of 750F (399C); the % molybdenum alloy steels to approximately 850F (454C); and the stainless steels to considerably higher temperatures depending upon the type used. Type 316 is also austenitic, non-magnetic, and thermally nonhardenable stainless steel like Type 304.
