Iron produced by the direct process was substance that gives iron its hardenability, relalive!y pure, containing about 99.5 per- the iron as originally reduced could not be cent iron (ferrite) and less than 0.1 percent hardened by heat treatment or any carbon. %nce Since carbon is Articulos Cuchillos Cuchillo EspadaTranslate this pageThe short of the story is that all steels types have an optimal hardness, but the heat treat is what determines the final resulting hardness of a blade:not the steel type itself. The long version plays out like this:The reason this myth exists and continues to be believed by many is ultimately because of branding and the claims made by knife

Heat Treating of Gray Irons:Part Two ::Total Materia ArticleHowever, even though gray iron can be hardened by quenching from elevated temperatures, heat treatment is not ordinarily used commercially to increase the overall strength of gray iron castings because the strength of the as-cast metal can be increased at less cost by reducing the silicon and total carbon contents or by adding alloying elements.

STAGES OF HEAT TREATMENT Heat treating is accomplished in three major stages:Stage 1-Heating the metal slowly to ensure a uniform temperature Stage 2-Soaking (holding) the metal at a given temperature for a given time and cooling the metal to room temperature Stage 3-Cooling the metal to room temperature HEATING STAGE The primary objective in the heating stage is to maintain uniform heat treatment and high chrome ironC21D 5 - Heat treatment of cast-iron - Patents Sitemap - Google. 10/08/2014, EP2785882A1 High modulus wear resistant gray cast iron for and low chrome alloy casting ball diversified oil quenching heat treatment process.

The microstructure of high chromium white cast iron grinding ball as-cast and after heat treatment was observed by metallographic microscope. The sample of 10mm* 10 mm* 8 mm in size at the center of the grinding ball was cut by weld and polished with 200 # to 1500 # metallographic sandpaper.

The flake graphite in gray irons is dispersed in a matrix with a microstructure that is determined by composition and heat treatment. The usual microstructure of gray iron is a matrix of pearlite with the graphite flakes dispersed throughout. In terms of composition, gray irons usually contain 2.5 to 4% C, 1 to 3% Si, and additions of manganese
