Hardness and micro-hardness testing.
At ATRONA, we conduct both hardness and micro-hardness testing to applicable testing standards and scales on a daily basis. Utilizing an array of machines, anvils, fixtures, and instruments, along with proven test methods and proprietary techniques, our technicians are well-equipped to examine and accurately measure the hardness of all types of metal, metal alloys, and metal components - regardless of the sample geometry. Difficult hardness testing assignments are no problem for our expert staff.
DIRECT HARDNESS: ATRONA is well versed in all Rockwell Scales and conversions. We have five hardness testers capable of measuring various scales with all sorts of anvils and fixturing capabilities. Unlike many other labs, we are actually able to secure and accurately measure even samples with challenging geometries. In most cases, WITHOUT DESTRUCTION to extract a cross section which can be placed flat. We regularly hardness test samples that are spherical, round, have an unusual shape, and/or are especially long, heavy, or have uneven weight distribution.
In addition to the most popular direct and superficial Rockwell scales (A, B, C, T, N), some of the Rockwell scales we have calibrated our machines to and conduct regularly include R, L, M and K scales.
MICRO-HARDNESS TESTING: We have cutting edge technology for micro-hardness testing and may be the leading independent lab in the Midwest with two fully-automatic systems capable of performing all sorts of routines and mapping procedures, and the ability to perform simultaneous testing on up to eight samples at the same time. With these systems, our technology is simply unmatched and also enables us to determine effective case depth on case hardened components, heat affected zone hardness on welded components, hard and soft spots on difficult to machine components, and various other procedures. Our micro-hardness testers are also capable of capturing vivid color photomicrograph images at a relatively fast rate and then, stitching them together to provide a full, seamless view of the entire specimen.
With precise, state-of-the-art technology and the ability to test multiple samples and projects simultaneously, ATRONA is well positioned to deliver high quality reports with speed and efficiency. This allows us to be more responsive and more price sensitive than many other labs. Please inquire about our heat treat testing program.
