Fatigue properties in terms of Whler curves and Fatigue strength at 2*106 cycles are compared between the different joining methods using load transfer capacity
Fatigue Properties and Endurance Limits of Stainless Steel Fatigue is a process of mechanical failure resulting from the application of repeated cyclic stress. The stress can be a combination of tensile and compression or fluctuating tensile strength.The result is that mechanical failure occurs at lower stresses than predicted by short-term tensile tests, provided there have been a large , best fe 430 steel equivalent
Fatigue Strength The fatigue strength or endurance limit is the maximum stress below which material is unlikely to fail in 10 million cycles in air environment. For austenitic stainless steel tube as a group, the fatigue strength is typically about 35 percent of the tensile strength.
NAS provids 316 eand 316L SS, which are molybdenum-bearing austenitic stainless steels. These steels contain a higher percentage of nickel than t 304SS. The resultan composition gives these steels much improved corrosion resistance in many aggressive environments.
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics.
Type 316 is the main stainless used in the marine environment, with the exception of fasteners and other items where strength and wear resistance are needed, then Type 304 (18-8) is typically used. Type Analysis of Stainless Type 316:

Both AISI 316 stainless steel and AISI 317 stainless steel are iron alloys. They have a very high 96% of their average alloy composition in common. There are 33 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
Alloy 316/316L (UNS S31600/S31603) is a chromium-nickelmolybdenum 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.
For austenitic stainless steels as a group, the fatigue strength is typically about 35 percent of the tensile strength. However, substantial variability in service results is experienced since additional variables such as corrosive conditions, type of loading and mean stress, surface condition, and other factors affect fatigue properties.

It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.

In this study, 316L stainless steel was used to mimic a scenario of oil and gas plant piping in order to determine good safety and reliability parameters. Fatigue tests were conducted at the Strength of Material Lab at Tenaga Nasional Berhad Research (TNBR) in Bangi. The fatigue specimens were tested in a tension-tension fatigue test
Stainless Steel - Grade 316 Grade 316 / 316L Technical Data Summary. Grade 316 is an improved version of CS 304, with the addition of molybdenum and a slightly higher nickel content. The resultant composition of CS 316 gives the steel much increased corrosion resistance in many aggressive environments.
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.
