With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Stainless 316, 316L, 317, 317L. 1 .888 282 3292 | UPMET.COM. Types 316 (UNS S31600), 316L(S31603), 317 (S31700), and 317L (S31703) are molybdenum -bearing austenitic stainless steels which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304.
In the range of 427 C 857 C, it is better not to continuously use SS 316, but when 316 stainless steel is continuously used outside this temperature range, it has good heat resistance. 316L stainless steel has better carbide precipitation resistance than AISI 316 and can be used in the above temperature range.
ApplicationsAlloy 316/316L (UNS S31600/ S31603) is a chromium-nickel- molybdenum austenitic stainless steel developed to provide improved corrosion resistance to Alloy 304/304L in moderately corrosive environments. It is often utilized in process streams containing chlorides or halides.
Penn Stainless inventory includes 316/316L (UNS S31600 / S31603), in sheet, sheet coil, plate, plate coil, bar, structural and tubular products. Generally, this grade is dual-certified to meet both 316 and 316L. Alloy 316/316L is ideally suited for applications requiring corrosion resistance superior to Type 304 and has good elevated temperaturebest ss 316 expansion coefficient

While alloys of copper and aluminium have equal or higher coefficients of expansion than austenitic stainless steels, it is the unique combination of high thermal expansion and low thermal conductivity that necessitates special precautions and procedures in the design and fabrication of the most commonly used 304/304L and 316/316L grades of best ss 316 expansion coefficient
The purpose of this Technical Report is to show the coefficient of thermal expansion (CTE) for various metallic and non-metallic materials used in springs and seals made by Bal Seal Engineering Co. 2.0 Scope
Temperature Expansion Coefficients of Piping Materials - Expansion coefficients for common materials used in pipes and tubes - aluminum, carbon steel, cast iron, PVC, HDPE and more; Thermal Expansion of Metals - Thermal expansion of some common metals
The span in the values may be caused by the variation in the materials themselves - or by the variation in the sources used. tK = tC + 273.16. tR = tF + 459.67. 1 in (inch) = 25.4 mm. 1 ft (foot) = 0.3048 m. Example - Linear Expansion. Calculate Thermal Pipe Expansion. Volumetric expansion coefficients of common fluids.
For example, if a three metre long Grade 304 bar (coefficient of expansion 17.2 m/m/C) is heated from 20C to 200C, the length increases by: 3.00 x 180 x 17.2 = 9288 m = 9.3 mm. The coefficient of thermal expansion of the austenitic stainless steels is higher than for most other grades of steel, as shown in the following table. Table 2.
The overall coefficient is the linear thermal expansion (in.) per degree Fahrenheit or Celsius. The CTE data is calculated by the change in length divided by the quantity of the length at room temperature, multiplied by the change of temperature.
The Thermal Expansion Characteristics of Stainless Steel Weld Metal Thermal expansion data are established to help in the proper selection of austenitic stainless steel filler metals to be used for welding dissimilar metal joints BY J.

In comparison, the SS AISI 316 boasts better resistance to chloride-rich conditions than the typical SS 304 thanks to the molybdenum addition. Uses for SS AISI 316 Also known as surgical stainless steel, marine steel, 316S16 (as per the British Standard ), the SS 316 is an austenitic chromium-nickel alloy.
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. They also offer higher creep, stress -rupture and tensile strength at elevated temperature. ATI 316 stainless steel can be susceptible to
stainless steels. The nine selected stainless steels are AISI 303, 304, 304L, 316, 317, 321, 347, 410, and 430. The recommended values include the percent thermal linear expansion, the instantaneous coefficient, and the mean coefficient of thermal linear expansion. These values are generated as a result of criti-

Linear thermal expansion coefficient is defined as material's fractional change in length divided by the change in temperature. Coefficient of linear thermal expansion is designated by the symbol (alpha). The SI unit of thermal expansion coefficient is (C)-1 and U.S. customary unit is (F)-1.
316 / 316L are austenitic stainless steels that contain molybdenum, which increases their resistance to many chemical corrodents and marine environments. 316L is an extra low carbon version of 316 stainless steel. These materials are more resistant to general corrosion and pitting/crevices than conventional austenitic stainless steels.

AISI 316L is the low carbon version of AISI 316 (0.08 %C) which may be susceptible to intergranular corrosion in certain corrosive media after it is welded or otherwise heated at temperatures between 430 and 860C. For welded applications avoid the unstabilised, higher carbon, versions.

Intergranular Corrosion Type 316 stainless steel is susceptible to precipitation of chromium carbides in grain boundaries when exposed to temperatures in the 800F to 1500F (425C to 815C) range.
AUSTENITIC STAINLESS STEEL (316) The structural material for the first wall and blanket of a fusion device must be of excellent integrity with well known and established properties since it will be subjected to radiation damage levels ~10-7 dpa/s, will be expected to operate at temperatures in the range of 100-600 C and for pulsed machines will be subject to damage caused by thermal fatigue as best ss 316 expansion coefficient
Stainless steels are iron based alloys containing at least 10.5% Chromium. They achieve their stainless characteristics through the formation of an invisible and adherent Chromium rich oxide film. Alloy 316 is a general purpose austenitic stainless steel with a face centered cubic structure.

The idea behind this thermal expansion calculator is simple: if you heat a material, it expands. If you cool it down, it shrinks. How much? Well, it depends on the property of the material called the "thermal expansion coefficient". In this article, we explain this concept in more detail.
Frictional properties of stainless steels Introduction. Frictional coefficients are perhaps more dependent on surface rather than material properties. Surface finish, cleanliness and lubrication of the mating surfaces largely determine the actual frictional resistance between mating surfaces. Friction coefficients
The more general way to calculate thermal expansion is to use the mean coefficients of thermal expansion, such as those given on the next page. To use the table on page 2, multiply the length of the part in inches, times the difference between room temperature and operating temperature, times the expansion coefficient.
Type 416 stainless steel is used for shafts, axles, gears, screws, bolts and any part that requires considerable machining. Should not be used for vessels under high pressures. Description. Type 416 stainless steel is a martensitic, free machining grade that can be hardened by heat treating to increase strength and hardness.
