Sample Collection and Chemical Composition Analysis of Steel
Steel is a most widely used material in the 21st century, with the exception of the automotive industry and the construction industry, whose usage covers almost all aspects of modern industry and production. As an important material, ......
Guaranteed hardenability structural steel (GB 5216-85)
Overview
The GB 5216-85 is the Chinese national standard for Quenched and Tempered Structural Steels. It contains minimum requirements for chemical and mechanical properties, testing, and inspection practices. Under this standard, steels are classified and evaluated in service depending on their ......
Stainless steel sulfuric acid - ferric sulfate corrosion test method GB 4334.2-84
Steel corrosion is a natural phenomenon and a concern for those involved in manufacturing and design. This is especially the case when it comes to stainless steel, as the presence of corrosion can lead to the breakdown of its superior properties. In order to evaluate and predict the corrosion perf......
Weldability test lap joint (CTS) welding crack test method GB 4675.2-84
In the CTS welding crack test, the most important is to prepare the test specimen. Before the weldment is tested, it needs to meet certain requirements, otherwise the results obtained will not be meaningful. For example, the welding itself should be performed skillfully, and the components of the w......
