Stainless steel 310S Pipe

 Stainless steel 310S is a blend of high temperature competencies and excellent ductility. It is designed for elevated temperature applications. The wire is capable to serve under very large temperatures upto 1150̊ C and it offers intermittent services up to 1140̊ C.

Benefits of stainless steel 310S pipe

Steel 310S is purposed to use for different applications in the highly moistened corroding conditions under lower temperatures. This alloy has lesser carbon percentage as compare to 310 which reduces its temperature strength as compare to 310.

Features of stainless steel 310S

This alloy offers extreme hardness even if it is used under cryogenic temperatures whereas other species are used normally under the same condition.

Corrosion Resistance Nature of Stainless Steel 310S

The high concentration of Chromium in 310S steel intends to enhance the high temperature strength as well as increases the corrosion resistance nature of alloy. Therefore 310S offers high resistance at normal temperature range in fact tends to retain better resistance property in the oxidation and carburising conditions with the increase in temperature.

Heat Resistance properties of Stainless Steel 310S

Steel 310S has good resistance to oxidation up to temperature of 1040°C and 1150°C continuously. This alloy also offers extreme opposition to thermal fatigue nature and periodic heating. This is the reason that this wire is preferably used in the conditions where Sulphur oxide gas is present under high temperatures.

Applications of stainless steel 310S pipe

1. 310S is used in manufacturing furnace components
2. Oil burner components
3. Carburising boxes and electrodes
4. Heat processing basket and jig and heat exchanging devices
