自動車用ファスナーの熱処理技術

With the development of the automotive industry, the requirements for automotive fasteners are getting higher and higher. China’s automotive high-strength fasteners are the main varieties of bolts, there are 8.8, 9.8, 10.9 and 12.9 grade 4 strength levels, these strength levels of fasteners have to be heat-treated to improve the overall mechanical properties of the product to achieve the specified tensile strength and flexural strength ratio, heat treatment process technology is the key to the production of automotive fasteners. 1. Factors affecting the heat treatment of automotive fasteners Automotive fastener heat treatment is generally known as tempering (quenched and then tempered by high temperature) treatment, tempering of raw materials, furnace […]
