Customer C: India's leading manufacturer of special alloy equipment, serving medium and large projects in the chemical and energy fields, with 20 years of industry experience. Its pressure vessel design has been adopted as a standard solution by many local petrochemical companies.
Cooperation status: TSM certified strategic supplier (cooperation for 3 years+)
A multinational chemical project undertaken by the customer requires titanium materials with hydrogen content ≤50ppm and iron content ≤0.15% (far exceeding the ASTM B348 standard)
The traditional supplier's products had hydrogen embrittlement cracks during welding, resulting in delayed equipment acceptance
The raw materials of titanium sponge need to be screened for high-quality batches with an oxygen content of ≤ 800 ppm
Control of hydrogen during vacuum melting
Avoid iron pollution in subsequent hot processing
1. Product: TA2 grade titanium plate
2. Source control:
3. Process innovation:
Double vacuum melting (VAR+EB furnace)
Add β-phase solution treatment after rolling
4. Full-process detection:
Spectral analysis every 50mm length (measured hydrogen content 45ppm±3)
Third-party SGS report confirms iron content of 0.12%
Only 28 days from order receipt to first batch delivery (industry average 45 days)
Provide a smelting process video for customer supervision
"TSM's metallurgical experts discovered the key points of hydrogen control even earlier than we did, and their technical memorandum has become training material for our new employees."
