Spring steel (GB 1222-64) (1)
Spring Steel (GB 1222-64) (1) Introduction Spring steel is a special type of steel that is used in the production of springs and other related products. It is a high carbon steel with a tensile strength range of between 35 to 75 kg/mm². The main chemical elements that make up spring steel are mang......
GB 12827-91 standard reference acetylene carbon black and identification method
Carbon black refers to black powdery or granular material, which is composed of many tiny particles with the average particle size of between 10 and 2000 nanometers. It is composedot many carbon atoms buthydrophobic in nature. Carbon black can be prepared by pyrolysis of hydrocarbons such as coal ......
Low alloy steel welding rod GB 5118-85
Introduction
Low alloy welding electrodes are used when welding low alloy steels and are mainly used as filler metal electrodes in gas metal arc (gmAW) and gas tungsten arc (GTAW) welding processes. Low alloy welding electrodes are made of metals and alloys such as nickel and aluminum, which allo......
Eddy current test method for titanium and titanium alloy pipes GB/T 12969.2-91
Abstract
This paper introduces GB／T 12969.2-91 Eddy Current Method for inspecting titanium and titanium alloy pipes. Eddy current method is an non destructive testing (NDT) technique for performing the inspection of titanium and titanium alloy pipes. The technique is an electromagnetic test whic......
GB 5126-85 Eddy current testing method for aluminum and aluminum alloy cold-drawn thin-walled pipes
Abstract
This article introduces the detection of eddy current of cold-drawn thin-wall tube material made of aluminum and aluminum alloy according to the national standard GB 5126-85. This method of eddy current testing is a reliable, high-efficiency nondestructive testing technology, which is wi......
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......
