JISCO achieves stable thin-gauge titanium coil production at 2.5mm
China's titanium processing sector has cleared a major technical hurdle. JISCO Hongxing Hongyu New Materials has achieved stable, repeatable production of 2.5mm thin-gauge titanium coils. The company accomplished this on a combined CSP and conventional hot strip rolling line in a single integrated campaign.
The result is significant on two levels. It closes a longstanding gap in China's domestic thin titanium supply. It also confirms that steel and titanium can share the same rolling line efficiently — a process known as steel-titanium mixed rolling.
For buyers sourcing titanium coil and specialty metal products, this development expands available supply and shortens lead times considerably.
What this production milestone covers
The project went well beyond hitting a target thickness. The technical team ran the process through multiple coil specifications and full quality verification before declaring it production-ready.
Key outcomes from the program include the following.
Stable mass production
2.5mm coils produced consistently across multiple campaigns without yield loss.
Mixed-rolling verified
Steel and titanium campaigns alternate on the same line with validated process changeover.
Multi-spec output
Several titanium coil widths and grades produced within the same rolling program.
Quality benchmarks met
Surface quality, thickness tolerance, and flatness all passed customer acceptance criteria.
Why this is technically demanding: Rolling titanium to 2.5mm on a hot strip mill — rather than cold-reducing from thick plate — requires precise control of heating, tension, and strip shape at every stage. Titanium behaves very differently from steel under heat and rolling pressure, making a shared production line particularly challenging to engineer.
How the technical team achieved stable output
The engineering team identified four process variables that directly affect thin titanium strip quality. Each required dedicated optimisation before the line could run stably.
Heating schedule optimisation
Titanium requires tighter thermal control than steel. The team developed specific heating profiles to manage slab temperature uniformity. Uneven heating leads to edge cracking and surface defects in thin gauge material.
Rolling rhythm and pass sequencing
Pass timing and rolling speed were adjusted for titanium's flow stress behaviour. The sequence was refined to maintain strip thickness within tolerance across the full coil length.
Inter-stand tension control
Titanium strip is prone to necking under excessive tension. The team set precise tension windows at each inter-stand position. This kept the strip stable and prevented gauge variation throughout the run.
Strip shape and flatness correction
Crown and edge drop were corrected through work roll bending and schedule adjustments. The result was flat, uniform coil geometry — a prerequisite for downstream forming and welding operations.
Together, these four improvements moved the process from trial runs to repeatable production. The methodology is now embedded in the line's standard operating procedures.
Why 2.5mm thin-gauge titanium coil matters to buyers
Thin titanium strip in the 2–3mm range has historically been difficult to source domestically in China. Most Chinese producers have focused on thicker plate, bar, and slab formats. As a result, importers and fabricators have relied on material from Japan, Russia, or Europe — with the lead times and cost premiums that entails.
JISCO's new capability changes that equation directly. Buyers who need thin-gauge titanium coil for stamping, forming, or welded fabrication can now access domestically produced material at competitive terms.

Target industries and applications
Thin titanium strip serves industries where corrosion resistance and strength-to-weight ratio are non-negotiable. JISCO's 2.5mm coil targets three primary markets.
New energy
Electrolysers, hydrogen fuel cells, and battery cooling systems rely on corrosion-resistant titanium components.
Chemical equipment
Heat exchangers, reactors, and process pipework in aggressive chemical environments require thin titanium strip.
Marine engineering
Offshore structures, desalination systems, and naval hardware demand long-life corrosion resistance.
All three sectors are expanding in China and internationally. Reliable domestic supply of 2.5mm titanium coil reduces import dependence and improves project scheduling for fabricators across these industries.
Broader impact on China's titanium supply chain
This achievement strengthens JISCO Hongxing Hongyu's standing among China's high-end titanium producers. The verified steel-titanium mixed rolling process also improves overall mill utilisation. The same line can handle both product families, giving the facility greater scheduling flexibility and faster order response times.
For China's titanium industry overall, the development signals growing domestic capability in thin strip formats. It reduces the country's reliance on imported coil for precision manufacturing applications. Industry observers expect this kind of capability to support future export growth in Chinese titanium products.
As global manufacturing continues to demand lighter, more durable materials, thin-gauge titanium coil production will become increasingly strategic. JISCO's investment positions it well for that long-term trend.

Thin-gauge titanium coil is hot-rolled titanium strip wound into coil form at thicknesses typically below 3mm. At 2.5mm, the material is suitable for stamping, deep drawing, and welded fabrication into complex components. Producing it on a hot strip mill — rather than cold-reducing from thick plate — is technically demanding. It requires precise control of heating, tension, and strip shape throughout the rolling process. Few Chinese producers have achieved this consistently, making JISCO's breakthrough commercially significant. For sourcing enquiries, visit lyhsteel.com.
Steel-titanium mixed rolling means alternating steel and titanium campaigns on the same hot strip rolling line. Titanium and steel have very different flow stress, thermal conductivity, and surface chemistry characteristics. Running both on one line requires carefully validated process changeover procedures. For a mill operator, this capability improves equipment utilisation and revenue per shift. For buyers, it means a more flexible and responsive supply chain for both steel and titanium products.
The three primary markets are new energy equipment (electrolysers, fuel cells, hydrogen storage systems), chemical processing equipment (heat exchangers, reactors, pressure vessels, and pipework), and marine engineering (offshore platforms, desalination plants, and naval vessels). All of these require materials that resist corrosion in aggressive environments, maintain structural integrity under load, and can be formed or welded into complex geometries. Thin titanium coil meets all three requirements in ways that plate or bar cannot in many fabrication scenarios.
CSP stands for Compact Strip Production. It is a process that combines continuous casting and hot rolling in a single integrated line — producing hot-rolled strip directly from liquid metal with a shorter route than conventional mills. CSP lines are well established for carbon steel. Adapting one to handle titanium alongside steel is technically challenging, which is why JISCO's combined CSP and conventional hot strip approach represents a meaningful capability advancement for the industry.
Expanding domestic production of thin-gauge titanium coil reduces China's reliance on imported strip. Previously, buyers sourced thin titanium coil primarily from Japanese, Russian, or European mills — often at significant price premiums and with 8–16 week lead times. Domestic supply from producers like JISCO shortens lead times, increases competition, and creates downward pressure on pricing for end-users in energy, chemical, and marine sectors. It also improves supply chain resilience for Chinese manufacturers and fabricators.
JISCO's technical team focused on four main areas. First, heating schedule optimisation to manage titanium's thermal sensitivity and prevent surface defects. Second, rolling rhythm and pass sequence adjustment to maintain gauge consistency across the full coil length. Third, inter-stand tension control to prevent necking and thickness variation. Fourth, strip shape parameter tuning — using work roll bending and schedule corrections — to achieve the flatness required for downstream forming. All four had to be solved together before the process reached stable production status.
