The type of mark depends on the standard to which the bolt was manufactured. Most often, bolts used in machinery are made to SAE standard J429, and bolts used in structures are made to various ASTM standards.
ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them. What is the Difference Between Mild Steel and High Tensile Oct 01, 2019 · Steel is a commonly used construction material across the world. From the earliest known production of steel in Anatolia in 1800 BC to the Wootz steel of South India in 6 th century BC to quench- hardened steel of China of 200 BC, there has always been upgradation in quality and production process of this most sought after alloy of iron and Structural Steel for Ships ::Total Materia Article
