1. Material Characteristics S20C is a low-carbon steel (equivalent to Chinese 20# steel or American AISI 1020), commonly used in the manufacture of carburized gears. Due to its low carbon content (0.17-0.23%), direct quenching cannot achieve high hardness. Carburizing treatment is necessary to increase the surface carbon content before quenching to obtain the desired “hard […]
Overview of 1.2550 Alloy Tool Steel 1.2550 (60WCrV7) is a high-toughness, impact-resistant alloy tool steel. It is well-known in the die steel industry, primarily characterized by its excellent impact resistance and fatigue resistance while maintaining high hardness. Simply put, it is a “hard but not brittle” metal material specifically designed for heavy-duty and strenuous work. […]
Diamond, the hardest natural substance, is essential for high-end cutting tools but requires reliable bonding to metal substrates due to its brittleness. Vacuum furnace brazing is the premier solution, overcoming issues like low bonding strength, oxidation, and short lifespan to ensure maximum durability.
This article details the vacuum quenching of 1.2344 (AISI H13) hot-work tool steel. It highlights the material's high-temperature durability for automotive and aerospace use, and provides a specific 4-phase heating and cooling cycle (reaching 1030℃) to achieve a theoretical hardness of HRC 54-56.
SIMUWU vacuum furnaces, with their precise temperature control and process adaptability, have developed a dedicated heat treatment solution for SKH9, achieving breakthroughs in both material performance and production efficiency, providing reliable technical support for high-end manufacturing.
This article provides an introduction to the complete manufacturing process of aluminum retarder coolers using a SIMUWU vacuum furnace, covering five key heating and holding stages.
