Stainless Steel Manufacturer | YC INOX
Stainless steel is alloyed from several raw materials including iron ore, chromium, nitrogen, silicon, and nickel. For steel to be considered "stainless," it must contain at least % chromium. This is vital because the chromium is what prevents corrosion from occurring. The presence of chromium creates a chemical reaction that forms ...

Most Common Uses of Stainless Steel
Feb 23, 2016 · Stainless steel's strength, resistance to corrosion and low maintenance make it the ideal material for a wide range of appliions. It also has a long life cycle and is 100% recyclable. There are over 150 grades of stainless steel, of which 15 are commonly used in everyday appliions.
Failure analysis of hot sinter screens of a sinter plant
Dec 15, 2013 · Failure analysis of a sinter screen in a sinter plant has been presented. The sinter screen is used for removing fines (<5 mm size) form the crushed hot sinter (temperature around 1000 °C) thereby facilitating the cooling of sinter as well as smooth running of blast screens are cracking prematurely within 15 material of the failed screens is found to be ASTM A297 HK .
METALLURGICAL USES FLUXES FOR METALLURGY
furnace is used to make steel, stainless steels, ferroalloys, and special alloys, whereas ferromanganese is often made in blast fur naces. Fluxes are used in all of these processes, and either limestone or lime is the major flux component with some dolomite, dolomitic lime, silica, alumina, and fluorspar being used. In ironmaking, the flux is added either by direct charging or through sinter ...

IRON AND STEEL
Mild steel. Mild steel is iron containing up to about % of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things nails, wire, car bodies, ship building, girders and bridges amongst others. High carbon steel

How stainless steel is made
To make stainless steel, the raw materials—iron ore, chromium, silicon, nickel, etc.—are melted together in an electric furnace. This step usually involves 8 to 12 hours of intense heat. Next, the mixture is cast into one of several shapes, including blooms, billets, and slabs.
Carbon Adsorption
The carbon is then removed by screening, across a carbon screen, allowing the liquid and finely ground ore (100 mesh) to pass through easily, and retaining the carbon on the screen. The carbon is then generally subjected to a heated solution (200 deg to 250 deg F) of (1%) sodium hydroxide and (%) cyanide and the gold is redissolved and removed from the carbon surface. At this point, the ...

Solids and Metals
The Specific Gravity SG is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference at this point the density of water is at the highest.. Specific gravities SG for common solids and metals can be found in the table below:
Silicon Steel (Electrical Steel)
Silicon steels are available with several types of insulation:C0: Also called bare, or oxide coated. This is a thin, tightly adherent oxide coating put on the material at the steel mill, or during the annealing process after stamping. This is the lowest cost insulation, but offers little resistance. C3: Enamel or varnish coating which offers excellent insulation, but parts so coated ...
Sulfuric Acid Resistant Alloys
Feb 10, 2017 · Hastelloys B and D were developed for handling sulfuric acid under very severe conditions, and they find use particularly in acid evaporators where dilute sulfuric is concentrated to about 65%. Alloy B is more resistant to boiling sulfuric up to about 60%, while D is employed chiefly over 60% concentration. Hastelloy alloy B, however, is not ...
How Steel Is Made | Metal Supermarkets
Jun 05, 2015 · The Composition of Steel. Steel is an alloy of iron and carbon. It can contain small quantities of silicon, phosphorus, sulfur and oxygen. The carbon content of steel is between to percent. This makes it harder than wrought iron but not as brittle as cast iron. Steel has a unique balance of hardness, flexibility and tensile strength.
