    They are more homogeneous than stainless than other high alloy steels, having carbide only in very small inclusions in the iron. The bulk material is a little bit harder than standard stainless steel such as St-304 (high-end alloys excluded), allowing them to hold a sharper and more acute edge without bending over in contact with hard materials.

  3. Austempering - Wikipedia

    en.wikipedia.org/wiki/Austempering

    The red line shows the cooling curve for austempering. Austempering is heat treatment that is applied to ferrous metals , most notably steel and ductile iron. In steel it produces a bainite microstructure whereas in cast irons it produces a structure of acicular ferrite and high carbon, stabilized austenite known as ausferrite .

    The fourth category of furnace is the high-efficiency condensing gas furnace. High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as ...

  7. Metallurgical furnace - Wikipedia

    en.wikipedia.org/wiki/Metallurgical_furnace

    A metallurgical furnace, often simply referred to as a furnace when the context is known, is an industrial furnace used to heat, melt, or otherwise process metals. Furnaces have been a central piece of equipment throughout the history of metallurgy ; processing metals with heat is even its own engineering specialty known as pyrometallurgy .

  8. Submerged-arc furnace for phosphorus production - Wikipedia

    en.wikipedia.org/wiki/Submerged-arc_furnace_for...

    The Submerged-arc furnace for phosphorus production is a particular sub-type of electric arc furnace used to produce phosphorus and other products. Submerged arc furnaces are mainly used for the production of ferroalloys. The nomenclature submerged means that the furnace's electrodes are buried deep in the furnace burden.

  9. Steelmaking - Wikipedia

    en.wikipedia.org/wiki/Steelmaking

    A "heat" (batch) of iron is loaded into the furnace, sometimes with a "hot heel" (molten steel from a previous heat). Gas burners may assist with the melt. As in BOS, fluxes are added to protect the vessel lining and help impurity removal. The furnaces are typically 100 tonne-capacity that produce steel every 40 to 50 minutes. [15]
