Inclusions in Specialty Alloys

When molten metal (steel, stainless steel, or nickel alloys) solidifies, the center of an ingot or slab is the last to freeze. While non-metallic impurities (oxides, nitrides, sulfides, silicides) settle throughout the ingot or slab, the greatest concentration of these inclusions settle along the solidification front…

Confused About Annealing and Heat Treating Terminology?

Confused About Annealing and Heat Treating Terminology? Back To All Articles Share: More Articles In the broadest sense, annealing is the process of heating an alloy to an elevated temperature to promote homogenous chemistry, equiaxed microstructure, and uniform mechanical properties to produce what is essentially stress-free, or “soft” material. In the stainless steel, nickel, and […]

How Stainless Steel Rusts

How Stainless Steel Rusts Share: More Articles All grades of stainless steel contain a minimum of 10.5% chromium within their chemical composition which allows for them to form a continuous protective oxide layer along their surface. This oxide layer is what makes stainless steel resistant to rusting and other forms of corrosion. Although stainless steel […]
