FAQS

Steel gage blocks are the most commonly sold type of gage block available. Part of their popularity is their ability to resist damage that can befall ceramic gage blocks more easily. Steel is a very hard and tough material, so dropping a steel gage block or another tool or object hitting it is not likely to cause damage. Steel gage blocks, however, are susceptible to corrosion and wear over longer periods of time. One advantage despite their susceptibility to long-term wear is that steel gage blocks are cheaper to buy initially and therefore cheaper to replace. Furthermore, steel is a common material found across parts, tools, and objects. This means that steel gage blocks are often made of the same material as the product they are being used to measure, which means they will have the same degree of thermal expansion as those products. Steel gage blocks are precise and highly accurate, increasing how often they are the gage block of choice.
