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, ......
Ultrasonic testing methods for steel forgings GB/T 6402-9l
Ultrasonic Testing of Forged Steel Products
Introduction
Ultrasonic testing (UT) is a non-destructive inspection method used to locate and identify discontinuities in forged steel products. In UT, sound waves are used to detect hidden defects in the material and provide a detailed cross-section ......
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 ......
