TOKKIN 350 is a chromium-nickel-molybdenum precipitation hardening stainless steel. In solution heat-treated and annealed conditions, it boasts excellent workability and high strength by heat treatment.

Compared to other precipitation hardening stainless steels, the addition of molybdenum provides superior corrosion resistance and oxidation resistance, and the absence of aluminum and titanium provides good weldability.

It also has excellent yield strength and cyclic fatigue strength, and is used for bellows, diaphragms, actuation valves, etc. which require long life under cyclic stress.

TOKKIN 350 - UNS S35000 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 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 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.

Exceptional Mechanical Performance

TOKKINTM 350 offers outstanding strength and corrosion resistance, making it suitable for components exposed to demanding environments. Its properties ensure long-lasting durability and reliability in precision applications such as actuators and watch parts.

Versatile Form and Finish Options

Customers can select from a range of tempers-including Bright Annealed (BA), 2B skin passed, and As Rolled (Hard)-as well as surface finishes like bright or dull. The product is available as coils or sheets to accommodate diverse fabrication needs.

Widely Trusted for Critical Applications

This PH stainless steel grade is widely utilized in applications that demand tight tolerances and consistent performance. Industries ranging from air conditioning to manufacturing precision valves and bellows benefit from its consistent quality and exporter/manufacturer support from Japan.

FAQ's of TOKKINa 350 - UNS S35000 | PH Stainless Steel:

Q: How is TOKKINTM 350 stainless steel typically processed for industrial use?

A: TOKKINTM 350 can be supplied in various tempers such as BA (Bright Annealed), 2B (Skin Passed), and As Rolled (Hard), which are selected based on the required mechanical properties and intended fabrication process for the end application.

Q: What applications is TOKKINTM 350 most suitable for?

A: This alloy is ideal for precision parts such as bellows, diaphragms, valves, air conditioner components, actuated valves, and watch parts, due to its excellent mechanical strength and corrosion resistance.

Q: When should I choose BA, 2B, or As Rolled temper for my project?

A: Choose BA (Bright Annealed) for a smooth, lustrous finish, 2B (Skin Passed) for a uniform, slightly dull surface, and As Rolled (Hard) when maximum strength is needed. Each temper provides specific benefits depending on the end-use requirements.

Q: Where is TOKKINTM 350 manufactured and exported from?

A: TOKKINTM 350 is manufactured in Japan and is supplied globally by recognized exporters, manufacturers, and suppliers, ensuring consistent quality and reliable delivery.
