What are SS High Temperature Fasteners
SS high temperature fasteners are specially designed connectors that are composed of hard stainless steel alloys that do not lose their strength and structural integrity during extreme temperatures and repeated thermal cycles. These clamps are necessary to withstand strenuous uses like aerospace, power plants, and industrial furnaces, where normal fastening items might fall short of service because of oxidation, thermal expansion, or material fatigue. Typical alloys are SS 309, 310, 321, and 630, which are selected due to high chromium and nickel content or stabilizing elements such as titanium, which increase heat resistance and long life.
