NM400 wear resistant steel plate has a very high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; it can improve the wear resistance of mechanical related parts; therefore improve the service life of machinery; reduce production costs. The surface hardness of the product j423methods of measuring case depth is usually Reached 360 - 450HB. NM400 wear resistant steel plate is used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.
Mechanical Methods In general this method is considered to be one of the most useful and accurate of the case depth measuring methods. It is the preferred method for determination for effective case depth and can be used effectively on all types of hardness cases.See all results for this questionWhat is the SAE method of measuring case depth?SAE J 423 a-1979 Methods of measuring case depth. The Society of Automotive Engineers, USA.See all results for this questionVARIATION OF EFFECTIVE CASE DEPTH WITH HOLDING Ihom, et al  have observed in a previous work that the effective case depth is a good measure of carbon penetration and thus the efficacy of an energizer can be assessed by the depth of case hardening (dc). He further said j423methods of measuring case depth case depth showed a gradual increase from 1.14mm to 2.2mm. Ihom , in a previous work had explained the
Total case depth is the total distance carbon, nitrogen or both have diffused inward from the surface of the part. It can be observed under a microscope as the distance from the surface to where you cannot clearly distinguish between the parts outer case and its inner core. Measuring total case depth is typically specified for parts requiring thinner cases. Effective case depth is the distance inward from a parts surface to a specific haSee more on paulo j423methods of measuring case depthEstimated Reading Time: 4 minsPublished: May 17, 2018Understanding and Measuring Decarburizationmum affected depth (MAD).
