Every material selection decision includes tradeoffs. Performance can come at a price. But there is little sense in paying for capabilities that are not needed. The following suggests a framework for selecting one of a family of corrosion-resistant materials from another. Comparisons Cost Cost is rarely ignored, so it is helpful to compare certain corrosion-resistant…

Grade Martensitic Stainless Steels. Description The addition of sufficient carbon to alloys of chromium and iron results in alloys that are true steels in that they can be hardened and tempered. Their structure upon rapid cooling from temperatures above 1600°F / 870°C is chiefly martensitic. Martensitic Steel Properties – Why select this material Magnetic…

Penetrant inspection is a popular detection method because it is relatively inexpensive and can be administered on a surface that is oriented in nearly any direction. Penetrant Inspection may take the form of Fluorescent Penetrant Inspection (FPI) or visible Liquid Penetrant Inspection (LPI). Each penetrant testing has its advantages, so the selected method will be…

Metallurgically, Bronze is a copper-based metal alloyed with tin, lead, aluminum or other elements to change the material’s physical or mechanical properties. The historic “Bronze Age” stretched from around 3000 B.C. to about 1000 B.C. Early craftsmen found the material easier to deal with than stone for many uses, and more durable than other materials…

Centrifugally cast components are typically thought of as straight walled cylindrical geometries such as tubes, pipe, or rings. They are often cast horizontally in permanent steel dies that have a removable end cap. Because the part must be extracted from the uncollapsible die, shaping is limited to geometries that have a straight or slightly drafted O.D. …
