Sachiya Steel International is one of the pioneer Manufacture and Supplier of Stainless Steel 317L Buttweld Fittings, which have somewhat higher thermal conductivities than the austenitic grades, which may be an advantage in certain applications. This expansion coefficient not only varies Stainless Steel 317L Elbow it also increases slightly with temperature. Stainless Steel 317L Reducer Butt Weld Pipe Fittings has a coefficient over the temperature range Zero Degree C to 100 Degree C, but increases above this temperature.
The effect of thermal expansion in Stainless Steel 317L Tee Butt Weld Pipe Fittings is most noticeable where components are restrained, as the expansion results in buckling and bending. A problem can also arise if Stainless Steel 317L Cross Butt Weld Pipe Fittings are fabricated together and then heated, where dissimilar coefficients will again result in buckling or bending.

In general, the quite high thermal expansion rates of the austenitic Stainless Steel 317L Bends mean that fabrications in these alloys may have more dimensional problems than similar fabrications in other alloy steels.
Localized stresses from expansion during heating and cooling of Stainless Steel 317L Stub End Butt Weld Pipe Fittings can contribute to stress corrosion cracking in an environment which would not normally attack the metal. These applications of Stainless Steel 317L End Cap require design to minimize the adverse effects of temperature differentials such as the use of expansion joints to permit movement without distortion and the avoidance of notches and abrupt changes of section.
