Description

Duplex 2205 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 Duplex 2205 Stainless Steel?

Duplex 2205 is a two-phase ferritic/austenitic – structures are approximately 50/50 austenite and ferrite and physical properties are a combination of the ferritic and the austenitic grades. It is the most widely used nitrogen enhanced duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades.It was developed to combat common corrosion problems encountered with the 300 series stainless steels. It demonstrates good fatigue strength, as well as outstanding resistance to stress-corrosion cracking, crevice, pitting, erosion and general corrosion in severe environments. Duplex Steel 2205 is not generally suitable for use at temperatures above 300°C as it suffers from precipitation of brittle micro-constituents, nor below -50°C because of its ductile-to-brittle-transition. It finds applications due to both excellent corrosion resistance and high strength. “Duplex” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430.

Duplex family consists of:

  • Lean Duplex SS – lower nickel and no molybdenum – 2101, 2102, 2202, 2304
  • Duplex SS – higher nickel and molybdenum – 2205, 2003, 2404
  • Super Duplex – 25Chromium and higher nickel and molybdenum “plus” – 2507, 255 and Z100
  • Hyper Duplex – More Cr, Ni, Mo and N – 2707
