Iron exhibits (mu_r) that is very high, but which decreases with decreasing purity. 99.95% pure iron exhibits (mu_rsim 200,000). This decreases to (sim 5000) at 99.8% purity and is typically below 100 for purity less than 99%. Steel is an iron alloy that comes in many forms, with a correspondingly broad range of permeabilities.

High-temperature laser scanning confocal microscopy (HT-LSCM) was used to observe the in-situ grain growth of austenite (γ-Fe) on the sample surface. The dependence of the arithmetic …

Miller: Pig Iron Market Update. The importation of basic pig iron has allowed EAF steelmakers to implement thin-slab casting technology to make drawing-quality flat-rolled sheet over the last 30 years. These pig iron imports have made it possible for these furnaces to use the available scrap supply—despite elevated alloy residual …

Materials of construction for equipment and piping in pharmaceutical processing plants must be resistant to corrosion from the high-purity water, the buffer solutions used in preparation of the products, and the cleaning solutions used to maintain the purity of the product.

Both low carbon steel and high purity iron substrates were used in this experiment. Coupons of AISI 1010 plain carbon steel (Alabama Specialty Products, Munford, Alabama) measuring 25 × 25 mm were polished to a 0.01 μm colloidal silica mirror finish.
