Introduction
This article will attempt to provide an overview of YB/T129-1997, a standard, or document, issued by the Chinese State General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) for plastic injection mould steel modules (PIPSMs). Specifically, the article will c......
Carbon tool steel (GB/T1298-1986)
Carbon tool steels are steels designed for machining, heat treating and other metal working tasks that are, for the most part, only accessible to non-metal working trades. Carbon tool steels have a low carbon content, typically from 0.5 percent to 1.2 percent, and are characterized by high-hardena......
16MnCr5 use
16MnCr5 Application
16MnCr5 is a commonly used medium-carbon steel alloy with a medium-carbon content of 1.60%. It is widely used in construction and engineering sectors. The use of 16MnCr5 is mainly due to its low cost and high strength-to-weight ratio. Its tensile strength is about 900 MPa, ena......
16MnCrB5 use
16MnCrB5 Definition
16MnCrB5 is a low-alloyed steel grade used primarily in the automotive industry, where it is particularly applicable in components operating under high tensile stresses, carburized and case-hardened. According to the UNI EN 10084 standard, 16MnCrB5 belongs to the group of hot-......
