Different Steel Types and Properties - ThoughtCo
WebType 316 (UNS 31600) is an austenitic chromium-nickel stainless steel alloy containing molybdenum. This addition increases corrosion resistance, improves resistance to pitting chloride ion solutions and provides increased strength at elevated temperatures. Properties of this austenitic stainless steel grade are similar to those of type 304 ... Scratch hardness is the measure of how resistant a sample is to fracture or permanent plastic deformation due to friction from a sharp object. The principle is that an object made of a harder material will scratch an object made of a softer material. When testing coatings, scratch hardness refers to the force necessary to … See more In materials science, hardness (antonym: softness) is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. In general, different materials differ in their hardness; for … See more There are three main types of hardness measurements: scratch, indentation, and rebound. Within each of these classes of measurement there … See more Rebound hardness, also known as dynamic hardness, measures the height of the "bounce" of a diamond-tipped hammer dropped from a fixed height onto a material. This type … See more In solid mechanics, solids generally have three responses to force, depending on the amount of force and the type of material: • They … See more Indentation hardness measures the resistance of a sample to material deformation due to a constant compression load from a sharp object. Tests for … See more There are five hardening processes: Hall-Petch strengthening, work hardening, solid solution strengthening, precipitation hardening, … See more The key to understanding the mechanism behind hardness is understanding the metallic microstructure, or the structure and arrangement of the atoms at the atomic level.
