Heat Resistant Titanium Rod for Industrial Furnaces

Inside an industrial furnace, things get hot. 300°C. 400°C. Steel starts to scale. Components warp. Creep becomes a problem.

Heat resistant titanium rod for industrial furnaces is not for extreme heat. It won't replace Inconel at 800°C. But for the 300°C to 400°C range, it does something nickel alloys can't - it saves weight. Lots of it.

Furnace racks. Jigs. Fixtures. Thermocouple tubes. Burner components.

Nickel alloys handle the really high temperatures. 600°C to 1000°C. But they're heavy. 8.4 g/cm³. And expensive.

Steel is cheap. But steel scales. Rust flakes off. Contaminates parts.

Titanium sits in the middle. Good to 400°C. Half the weight of nickel alloys. No scaling. No rust.

For heat resistant titanium rod for industrial furnaces, the sweet spot is applications that run at moderate temperature but get lifted in and out of the furnace by hand. Weight matters there.

Grade 2 works to 300°C. Above that, oxidation accelerates. The surface darkens. A thin oxide layer forms. Still usable, but watch it.

Grade 5 works to 400°C. It holds strength better. Creeps less.

Push either grade to 500°C and the oxide layer grows fast. Gets thick. Flakes off. The rod loses section.

For heat resistant titanium rod for industrial furnaces, stay at or below 400°C. Above that, use Inconel.

Grade 5 costs more. But it runs hotter and stronger. For furnace parts that see constant heat and load, Grade 5 is worth the extra cost.

Grade 2 is fine for parts that run cooler or don't carry heavy weight.

Furnace racks. Parts go on the rack. Rack goes into the furnace. Then pulled out hot. Titanium handles the temperature. Stays straight. 20mm to 40mm rod. Grade 2.

Heat treatment jigs. Hold parts during hardening or annealing. Complex shapes machined from rod. Grade 5 for higher temp.

Thermocouple protection tubes. Small diameter. 10mm to 16mm. Grade 2. Protects the sensor without melting or scaling.

Burner tips. See direct flame. Short bursts to 500°C. Grade 5.

For heat resistant titanium rod for industrial furnaces, each application relies on the rod holding shape at temperature.

A furnace rack might be 2 meters long. 50mm diameter. Stainless steel rack weighs about 30kg. Titanium rack weighs about 17kg.

Operators lift these racks in and out of the furnace all day. Titanium saves their backs. Less fatigue. Fewer dropped parts.

For heat resistant titanium rod for industrial furnaces, the weight savings is the main selling point.

At room temperature, titanium is bright silver.

• At 300°C, it starts to darken. Light straw color. Then brown.

• At 400°C, it turns dark gray. The oxide layer is thin but visible.

• At 500°C, the oxide thickens. Flakes start to form. The surface becomes rough.

The oxide layer is not structural failure. But flaking oxide contaminates furnace atmosphere. Not good for clean processes.

Creep is slow bending under load at high temperature.

Grade 2 at 300°C under heavy load will slowly bend over time. Months, not days.

Grade 5 at 400°C is better. Less creep.

For permanent furnace fixtures that see constant load, design with creep in mind. Or plan to replace them every couple of years.

Titanium expands less than steel.

That means less growth when hot. Fixed rods push less on their supports. Fewer stress problems.

Furnace rods get threaded. Drilled. Slotted.

Grade 2 machines like soft stainless. Easy.

Grade 5 needs carbide. Low speed. High feed. Don't rub.

We supply rod cut to your length. Turned to tolerance. Ready for your mill.

Titanium reacts with some gases at high temperature.

For heat resistant titanium rod for industrial furnaces, ordinary air furnaces are fine. Controlled atmospheres need checking.

For 400°C and below, titanium wins on weight. For higher temperature, you need Inconel.

You have a furnace that runs at 300°C to 400°C. Your current racks are stainless steel. Heavy. Rusty. Hard to lift.

Heat resistant titanium rod for industrial furnaces solves the weight problem.

Grade 2 for 300°C. Grade 5 for 400°C.

Half the weight of stainless. No rust. No scale.

For furnace racks. For jigs. For fixtures.

Keep the heat. Lose the weight.
