Description

317/317L Stainless Steel Pipes for Heating Furnaces! Low Prices

A furnace is a device used for high-temperature heating. It is a container that is heated to a very high temperature, so that substances that are put inside it, such as metal, will melt or burn.

The name derives from Latin word fornax, which means oven. The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces.

In metallurgy, several specialized furnaces are used. These include:

Furnaces used in smelters, including:

  • The blast furnace, used to reduce iron ore to pig iron

Steelmaking furnaces, including:

  • Puddling furnace
  • Reverberatory furnace
  • Bessemer converter
  • Open hearth furnace
  • Basic oxygen furnace
  • Electric arc furnace
  • Electric induction furnace

Furnaces used to remelt metal in foundries.

Furnaces used to reheat and heat treat metal for use in:

  • Rolling mills, including tinplate works and slitting mills.
  • Forges

What is 317/317L Stainless Steel?

317 is a higher chromium, nickel and molybdenum version of 316 stainless designed principally for increased strength and corrosion resistance when compared with 304/304L and 316/316L.

317L is similar to 316 stainless steel but provides improved resistance to atmospheric corrosion, to many organic and inorganic chemicals and to food and beverages and can produce stronger welds due to the low carbon content. 317L’s molybdenum content increases to 3 to 4% from the 2 to 3% found in 316 and 316L. It has the same high strength and corrosion resistance as 317 steel but can produce stronger welds due to the low carbon content.

Alloy 317LMN and 317L are molybdenum-bearing austenitic stainless steel tube with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic stainless steel pipe such as Alloy 304. In addition, 317LMN and 317L alloys offer higher creep, stress-to-rupture, and tensile strengths at elevated temperatures than conventional stainless steels. All are low carbon or “L” grades to provide resistance to sensitization during welding and other thermal processes. Grade 317L is austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. The low carbon provides resistance to sensitization during welding and other thermal processes. 317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding.

The “M” and “N” designations indicate that the compositions contain increased levels of molybdenum and nitrogen respectively. The combination of molybdenum and nitrogen is particularly effective in enhancing resistance to pitting and crevice corrosion, especially in process streams containing acids, chlorides, and sulfur compounds at elevated temperatures. Nitrogen also serves to increase the strength of these alloys. Both alloys are intended for severe service conditions such as flue gas desulfurization (FGD) systems.

In addition to excellent corrosion resistance and strength properties, the Alloys 316, 316L, and 317L Cr-Ni-Mo alloys also provide the excellent fabricability and formability which are typical of the austenitic stainless steel tubing .
