Brinell hardness tester is both fast and accurate

NovaCast’s semi-automatic digital Brinell hardness tester uses a pressure sensor instead of traditional weights to perform Brinell hardness tests. The testing force and dwell time is set via a control panel. A digital Brinell microscope with adjustable LED illuminator automatically reads the indentation and instantly displays test results, making it both fast and extremely accurate. The video shows hardness testing of a drive shaft machined from AISI 431 (BS431S29) stainless steel billet. This high chromium, low carbon martensitic stainless steel has high hardenability, strength and corrosion resistance, and has been heat treated by case hardening.
