Have you ever wondered how raw metal transforms into flexible, high-strength coils for chemical plants and aircraft? A titanium strip powers some of the most critical applications in modern industry. You can find these versatile metal ribbons in heat exchangers, medical devices, and marine hardware.
Manufacturing a premium titanium strip requires extreme temperature controls, specialized rolling mills, and deep metallurgical knowledge. At TSM Titanium, we convert raw titanium sponge into high-precision mill products. We follow rigorous international quality standards to deliver consistent performance across every batch.
In this guide, you will explore every stage of our production process. We will walk through melting, hot rolling, cold processing, vacuum annealing, and quality testing. You will also discover how selecting certified factory partners improves your procurement outcome.
Raw Material Selection: Preparing High-Purity Titanium Sponge
Superior metal products always begin with top-tier raw materials. We start our production line with high-purity titanium sponge. This porous metal form comes from processing raw titanium ore through chemical reduction.
Our metallurgy team inspects every incoming sponge shipment for chemical purity. We mix the sponge with specific alloying elements when producing custom titanium alloys. For commercially pure products like Grade 2, we keep the pure titanium content above 99%.
Vacuum Arc Remelting (VAR)
We press the titanium sponge into dense electrode blocks using heavy hydraulic compactors. Then, we place these electrode blocks inside a Vacuum Arc Remelting furnace.
Double and Triple Melting
We melt the metal two or three times under a strict vacuum environment. This process eliminates volatile impurities and removes gases like hydrogen, nitrogen, and oxygen.
Heavy Ingot Formation
The molten titanium cools slowly into massive, solid titanium ingots. These ingots weigh several tons and feature a uniform chemical structure.
Purification stops internal defects before mechanical processing begins. Clean ingots ensure your final coils maintain maximum tensile strength and corrosion resistance.
From Ingot to Slab: The Primary Hot Forging Process
Solid ingots are far too thick for direct coil rolling. We must break down the cast ingot structure through primary hot forging.
We load the titanium ingot into specialized pre-heating furnaces. We heat the metal to precise temperatures between 900°C and 1150°C. Titanium reacts quickly with oxygen at elevated temperatures, so we carefully limit heating times.
- Heavy Hydraulic Pressing: Giant hydraulic presses apply thousands of tons of force to squeeze the heated ingot.
- Grain Structure Refinement: Forging breaks down coarse cast grains into fine, uniform wrought structures.
- Slab Formation: We shape the round ingot into flat rectangular slabs, often called blooms or billets.
Engineers inspect the forged slabs after cooling. We grind away surface scale or minor imperfections to prepare a smooth surface for rolling mills.
Hot Rolling: Shaping the Core Metal
Hot rolling turns thick forged slabs into continuous, thin metal coils. This stage reduces metal thickness drastically while extending its length.
We reheat the conditioned slabs in a continuous heating furnace. The glowing slab feeds directly into our heavy-duty hot rolling mill stands.
- Roughing Passes: Heavy rolls reduce slab thickness from several inches down to a fraction of an inch.
- Finishing Passes: The metal passes through continuous rolling stands at high speeds to reach target strip thickness.
- Coiling Process: The long hot metal rolls tightly onto a heavy coiler mandrel.
Hot rolling creates a uniform coil structure with consistent mechanical properties. The metal surface forms a thin oxide scale during hot processing. We must remove this scale before advancing to cold working stages.
Descaling and Acid Pickling: Cleaning the Surface
You cannot cold-roll a metal strip with oxide scale on its surface. Hard oxides damage delicate cold rolling rolls and ruin surface finish quality.
We use a two-step cleaning line to restore a bright, clean metallic surface.
- Mechanical Descaling: We pass the coil through tension levellers or shot blasting machines. This action cracks and loosens tough surface oxides.
- Chemical Acid Pickling: We submerge the continuous strip in controlled acid baths containing nitric and hydrofluoric acid. The acid dissolves remaining scale cleanly.
- Rinsing and Drying: High-pressure water jets rinse away all acid residue, followed by warm air drying.
This cleaning sequence delivers a pristine, silver-white titanium surface ready for precision cold reduction.
Cold Rolling and Vacuum Annealing: Achieving Precision Tolerances
Cold rolling gives the metal strip its final thin gauge, smooth surface finish, and exact dimensions. Unlike hot rolling, we perform cold rolling at room temperature.
We feed the pickled continuous coil into high-precision Sendzimir mills or multi-roll cold rolling mills.
Multi-Pass Thickness Reduction
Specialized work rolls squeeze the metal repeatedly. We reduce thickness in small, controlled increments to prevent surface cracking.
Work Hardening Control
Cold working increases metal hardness and strength, but reduces flexibility. The metal becomes stiffer after each rolling pass.
Vacuum Annealing Treatment
We load work-hardened coils into giant vacuum annealing furnaces to relieve internal stress and restore ductility.
We repeat the cold rolling and vacuum annealing cycle multiple times. This allows us to produce ultra-thin strips with precise thickness tolerances down to fractions of a millimeter.
Surface Finishing, Slitting, and Edge Processing
Once we achieve the target gauge, we customize the metal strip to match exact customer project requirements.
Industrial buyers often need custom widths, specific coil weights, and bright surface finishes for automated production lines.
- Precision Rotary Slitting: High-speed rotary knives cut wide master coils into narrow custom strips according to client specifications.
- Edge Conditioning: We smooth sharp sheared edges using edge-rounding machinery to ensure safe handling and seamless welding.
- Surface Polishing: Depending on your application, we offer bright-annealed, matte, or polished surface finishes.
Custom slitting allows us to deliver ready-to-use materials for stamping, forming, or continuous tubing production.
Rigorous Quality Assurance and Factory Testing
B2B buyers demand complete reliability for critical industrial applications. We subject every batch to strict quality control protocols before packing and shipping.
Our quality laboratory tests physical, chemical, and mechanical properties against international engineering standards.
Chemical Composition Analysis: Spectrometers verify element concentrations to guarantee full compliance with ASTM standards.
Tensile and Yield Testing: Mechanical testing machines measure yield strength, tensile strength, and elongation rates.
Ultrasonic and Eddy Current Inspection: Non-destructive testing methods detect internal voids, cracks, or inclusions.
Dimensional Precision Inspection: Laser micrometers measure thickness uniformity across the entire coil width and length.
Every shipment includes complete Mill Test Certificates (MTC) according to EN 10204 3.1. You receive full material traceability from raw sponge to finished coils.
Understanding Grade 2 Titanium Strip Specifications
Grade 2 titanium stands out as the workhorse of commercially pure titanium grades. It balances excellent formability with outstanding corrosion resistance and moderate strength.
Engineers widely select Grade 2 for demanding chemical processing environments and marine equipment.
