Japan Titanium Iron (JIS G2309-1986)
Japan Titanium Iron (JIS G2309-1986) is an alloy of iron and titanium, with a maximum titanium content of 0.10%. It is intended primarily for use in the manufacture of rolling stock and railway components. The alloy has been widely used in Japan since the 1960s, and is one of the most widely used titanium alloys in the world.
The alloy was developed using a combination of hot and cold working procedures, in order to take advantage of the superior physical and mechanical properties of titanium compared to those of other metals. The result is a material with excellent ductility, corrosion resistance and weldability.
The composition of the alloy is designed to provide a good balance between strength, toughness and workability. The alloy is made up of 52.8-55.1% iron, and 44.9-47.2% titanium, with a maximum of 0.10% carbon and 0.50% manganese. It also contains 0.10% phosphorus and 0.07% sulfur. The melting point of the alloy is 1660°C.
The physical properties of the alloy are excellent. It has a relatively high tensile strength of 860-940MPa, and good elongation. It has a hardness of 89-95 HRB, and a modulus of elasticity of 200Gpa. It also has excellent corrosion resistance, with the alloy showing little to no rust even when exposed to harsh environments.
The alloy is used in many applications due to its excellent properties. It is used in the manufacture of railway components and rolling stock, as well as in mechanics and hydraulics, such as pumps and valves. It is also used as an engineering material, in the manufacture of tools, and in nuclear power plants.
The alloy is available in a variety of forms, including rods, plates, sheets, bars and wires. It can also be machined and formed into components.
Overall, Japan Titanium Iron (JIS G2309-1986) is an excellent alloy, with superior properties compared to other metals. It is used in a variety of applications, due to its excellent ductility, corrosion resistance and weldability, and is one of the most widely used titanium alloys in the world.
