High temperature fastener

The upper limit of the operating temperature for our conventional stainless steel and alloy steel fasteners is 400°C, upon exceeding which, the various properties of the fasteners will decline sharply. The high-temperature fasteners we are talking about refer to the fasteners with the operating temperature from 400°C to 1200°C, and we can provide the fasteners within this range. However, the practical application and raw materials of high-temperature fasteners are indeed a very complicated and rigorous process, which involves information and technology on expansion coefficient, anti-corrosion and anti-rust performance, mechanical properties at high temperature, high-temperature anti-loosening, high-temperature disassembly, etc. We can provide our customers with professional technical advice, thus escorting your high temperature fastener applications. Our high temperature fasteners are mainly used in heat treatment equipment, steam turbines, engines, injection molding and hot extrusion equipment, etc. The high temperature fastener materials provided by our company mainly include precipitation-hardening stainless steel, high temperature stainless steel and special alloy steel. The specific material grades are introduced as follows:
