10/27/2022 0 Comments Ball indenter irhdThe effects of four different sizes of steel and WC ball indenters on different Rockwell hardness scales are studied and compared with the experimental tests. In this paper, finite element analysis (FEA) is used to simulate the HR indentaiton process using steel and WC ball indenters on the same test materails under the same testing conditions. However, significant differences occur in Rockwell hardness tests depending on whether the ball indenter that is used is made of steel or WC. For the Rockwell scales that use a ball indenter, either a steel or tungsten carbide (WC) ball indenter is permitted to be used in the current standards of ASTM International and the International Organization for Standardization (ISO). Indenter ball 0.395 ± 0.005 / Clamping 3.35 ± 0.15 / Hole 1.00 ± 0.The Rockwell hardness (HR) test is a valuable and widely used indentation hardness test for evaluating mechanical properties of metallic materials. Different anvils are provided to accommodate any type of sample. The visible indenter allows to reach extreme points and small details.The Micro IRHD works in any condition due to the Affri System where load forces are directly applied along the indenter’s axis, without ratios and levers. It is not affected by vibration and it doesn’t need to be leveled.Load forces are applied through a dynamometric load cell.To perform the test just act on the elevating screw and bring the sample to make contact with the indenter, then pull the START lever and apply the load within seconds results appear. Thickness ≥ 4 mm / Range: 35 - 85 IRHD or 30 - 95 IRHD Method H (High hardness), Indenter ball 1.00 0.01 / Clamping 20 1. HARDNESS TESTING ON THERMOPLASTIC, RUBBER AND VULCANIZED RUBBER Test Automatic hardness testers, portables or bench top, for Shore and IRHD hardness. #BALL INDENTER IRHD CODE#After test run the bar code data are added with results and immediately returned to the order management system. This hardness tester gets all information fully automatically. Test cycles or sample drawings can be loaded directly from a central system by means of a bar code scanner. It is a powerful analysis system with easy and fast test settings, live statistics and graphs. #BALL INDENTER IRHD SOFTWARE#This software is user friendly and easily managed by touchscreen. The pre-installed software controls the whole instrument during the entire cycle avoiding operator errors. Remote service and assistance through internet connection. #BALL INDENTER IRHD FULL#IRHD is equipped with a 10.4” LCD touchscreen PC support with USB and Ethernet data outputs for a full connectivity with network devices, printers or keyboards. The R&R (repeatability and reproducibility) data is at the top of its class. There is no need to perform a second test, the first one is absolutely precise. Accurate measurements, even on the first test, eliminate the need for multiple tests. Results are not affected by any structural deflection, misalignment or external vibration. Each load force is automatically programmed and controlled assuring perfect linearity in every range eliminating the problems associated with traditional dead weight system testers. Load forces are applied through load cells and electronically controlled in “Closed Loop” (Pat.
