Description	TOKKIN™ 350 is a chromium-nickel-molybdenum precipitation-hardening stainless steel designed to provide excellent workability in the solution-treated condition and outstanding strength after heat treatment. Compared with conventional precipitation-hardening stainless steels, TOKKIN 350 contains molybdenum, which significantly improves corrosion resistance and oxidation resistance. In addition, the absence of aluminum and titanium contributes to improved weldability and fabrication characteristics. The alloy exhibits excellent yield strength and cyclic fatigue performance after aging treatment, making it particularly suitable for components subjected to repeated stress and long service life requirements. Main Features: Excellent Workability Before Aging Solution-treated and annealed material can be easily formed, stamped, and fabricated into complex shapes. High Strength Through Precipitation Hardening Heat treatment significantly increases strength and spring characteristics while maintaining dimensional stability. Superior Corrosion Resistance Molybdenum addition provides enhanced corrosion resistance compared with many conventional precipitation-hardening grades. Excellent Oxidation Resistance Suitable for applications exposed to elevated temperatures and cyclic environmental conditions. Good Weldability The absence of aluminum and titanium reduces welding-related challenges and helps maintain consistent mechanical properties. Outstanding Fatigue Performance High yield strength and cyclic fatigue resistance make it ideal for components subjected to repeated loading and vibration. TOKKIN 350 is widely used in bellows, diaphragms, precision valves, actuator components, air-conditioning control systems, watch parts, and other precision applications where long fatigue life, corrosion resistance, and high strength are required.
