Today I would like to introduce to you a superficial Rockwell hardness tester with a smaller testing force than the Rockwell hardness tester:
Superficial Rockwell hardness tester is a type of Rockwell hardness tester. It uses smaller test force. When testing some small and thin workpieces, using Rockwell hardness tester will lead to inaccurate measurement values. We can use Superficial Rockwell hardness tester...Read more -
Universal hardness tester(Brinell Rockwell Vickers Hardness Tester)
The Universal hardness tester is actually a comprehensive testing instrument based on the ISO and ASTM standards, allowing users to conduct Rockwell, Vickers and Brinell hardness tests on the same instrument. The Universal hardness tester is tested based on Rockwell, Bri...Read more -
Introduction of Portable Leeb Hardness Tester
Nowadays, portable Leeb hardness testers are mostly used for on-site inspection of many workpieces. Let me introduce some common knowledge about Leeb hardness testers. Leeb hardness test is a new hardness testing method proposed by Swiss Dr. Leeb in 1978. Principle of Le...Read more -
Vickers hardness tester system
Origin of Vickers hardness tester Vickers hardness is a standard for representing material hardness proposed by Robert L. Smith and George E. Sandland in 1921 at Vickers Ltd. This is another hardness testing method following the Rockwell hardness and Brinell hardness testing methods. Principle o...Read more -
Brinell Hardness Tester Series
The Brinell hardness testing method is one of the most commonly used testing methods in metal hardness testing, and it is also the earliest testing method. It was first proposed by the Swedish JABrinell, so it is called Brinell hardness. The Brinell hardness tester is mainly used for hardness det...Read more -
Test method for hardness of heat treated workpiece
superficial heat treatment is divided into two categories: one is superficial quenching and tempering heat treatment, and the other is chemical heat treatment. The hardness testing method is as follows: 1. superficial quenching and tempering heat treatment superficial quenching and tempering heat...Read more -
Company development mileage – Participation in standard development-move new factory
1. In 2019, Shandong Shancai Testing Instrument Co., Ltd. joined the National Testing Machine Standardization Technical Committee and participated in the formulation of two national standards 1)GB/T 230.2-2022:”Metallic Materials Rockwell Hardness Test Part 2: Inspection and Calibration of ...Read more -
Hardness Tester Maintenance
Hardness tester is a high-tech product integrating machinery, liquid crystal and electronic circuit technology. Like other precision electronic products, its performance can be fully exerted and its service life can be longer only under our careful maintenance. Now I will introduce to you how to ...Read more -
Select various hardness testers for testing based on material type
1. Quenched and tempered steel The hardness test of quenched and tempered steel mainly uses Rockwell hardness tester HRC scale. If the material is thin and HRC scale is not suitable, HRA scale can be used instead. If the material is thinner, surface Rockwell hardness scales HR15N, HR30N, or HR45N...Read more -
Hardness Tester/ Durometer/Hardmeter type
The hardness tester is mainly used for the hardness test of forged steel and cast iron with uneven structure. The hardness of forged steel and gray cast iron has a good correspondence with the tensile test. It can also be used for non-ferrous metals and mild steel, and the small diameter ball in...Read more -
Updated Rockwell hardness tester which using electronic loading test force replacing weight force
Hardness is one of the important indexes of mechanical properties of materials, and hardness test is an important means to judge the quantity of metal materials or parts. Since the hardness of a metal corresponds to other mechanical properties, other mechanical properties such as strength, fatigu...Read more -
Relationship between Brinell, Rockwell and Vickers hardness units (hardness system)
The most widely used in production is the hardness of press-in method, such as Brinell hardness, Rockwell hardness, Vickers hardness and micro hardness. The obtained hardness value essentially represents the resistance of the metal surface to the plastic deformation caused by the intrusion of for...Read more
