Ultrasonic flaw detection and quality rating method for steel castings (abstract) GB 7233-87
Abstract
This study focused on the ultrasonic nondestructive testing and quality evaluation method of cast-steel parts. The study reviewed and evaluated the current testing capabilities of various establishments, including the simulation tests and judgment criteria of surface and internal defects......
penetration testing and rating methods for indications of flaws in steel castings (abstract) GB 9443-88
Abstract
Industrial casting steel parts are used in many fields of engineering and they are often subjected to many types of forces that could cause damage to the parts. To ensure these parts are durable and can withstand heavy loads, it is important to check them through penetration testing and d......
Dimensional tolerances of castings with casting hardness test blocks (abstract) GB 6414-861
Introduction
GB 6414-861 is a national standard about castings in China. The main purpose of this standard is to specify the dimensions, tolerances and hardness test requirements for different types of castings.
Definition of GB 6414-861
GB 6414-861 is a standard for Castings. It specifies the ......
Technical specification for testing concrete strength by core drilling method
The full penetration diamond core method is a viable and cost-effective process for accurately assessing the compressive strength of concrete, minimizing the risk of obtaining false or misleading test results. This method provides a reliable measure of the concretes strength, since it wets the e......
8Cr3 use
Introduction
AISI 4140/AISI 4140 Steel Grade is a chromium-molybdenum alloy steel, the chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. This grade generally exhibits good weldability, machinability, relatively mild temperi......
C50 use
Benzyl Benzoate
Benzyl benzoate, also known as BB, is a white-coloured, liquid solvent compound primarily used in the preservatives and topical medications. It is a salicylate ester, which means it is derived from an acid and a matching alcohol, in this case salicylic acid and benzyl alcohol. BB ......
Chemical composition and mechanical properties of weld metal with different grades of welding wire
Welding electrodes are made of steel and applied with a superior form of wire for combining two or more metal objects. Electronically and chemically, there is no inflexible regulation over their manufacture, and therefore the compositions and mechanical properties of different models are varied an......
