Working with VT1-00-M
Is VT1-00 easy to machine?
Use sharp, positive-rake carbide, low speed (25–50 m/min) with heavy rigid setup and flood coolant; soft CP Ti gums and builds up on the edge, and chips can ignite in fine form.
Can VT1-00 be welded?
Very good weldability by GTAW/PAW/EBW with high-purity argon trailing shields and backing; keep interpass temp low, weld surfaces clean, and reject any straw/blue/grey oxide colour (hydrogen/oxygen pickup embrittles).
Can VT1-00 be formed, bent or molded?
Excellent cold formability — deep draws, tight bends (≈2t) and roll forming in the annealed condition; allow for high springback and consider 200–400 °C warm forming for heavy sections; never use lead/chlorine-bearing lubricants.
What surface finishes work on VT1-00?
Pickle in HNO₃/HF to remove alpha case and heat tint before service; colour anodising and plasma electrolytic oxidation give decorative or wear layers; avoid iron contamination from steel tooling and grit.

VT1-00-M — frequently asked
What is VT1-00-M used for?
VT1-00-M is typically used for chemical process equipment, medical implants, marine components and cryogenic vessels. In short: softest CP titanium; best-forming CP grade; CIS equivalent to Grade 1.
What is the yield strength of VT1-00-M?
VT1-00-M has a typical yield strength of 230 MPa (33.4 ksi) and a tensile strength of 330 MPa (47.9 ksi) — weaker than 93% of titanium grades. Strength varies by condition: see the 4 listed tempers.
Is VT1-00-M easy to machine?
Not especially — machinability is rated fair (42/100, better than 98% of titanium grades). Use sharp, positive-rake carbide, low speed (25–50 m/min) with heavy rigid setup and flood coolant; soft CP Ti gums and builds up on the edge, and chips can ignite in fine form.
Can VT1-00-M be welded?
Yes — weldability is rated excellent (88/100). Very good weldability by GTAW/PAW/EBW with high-purity argon trailing shields and backing; keep interpass temp low, weld surfaces clean, and reject any straw/blue/grey oxide colour (hydrogen/oxygen pickup embrittles).
What surface finishes work on VT1-00-M?
Pickle in HNO₃/HF to remove alpha case and heat tint before service; colour anodising and plasma electrolytic oxidation give decorative or wear layers; avoid iron contamination from steel tooling and grit.
Can VT1-00-M be formed, bent or molded?
Excellent cold formability — deep draws, tight bends (≈2t) and roll forming in the annealed condition; allow for high springback and consider 200–400 °C warm forming for heavy sections; never use lead/chlorine-bearing lubricants.
What is the maximum service temperature of VT1-00-M?
VT1-00-M is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between VT1-00-M and VT1-00-H?
M is the default condition — default stock condition: maximum ductility for deep drawing, roll forming, lining and cladding. H: pick when higher strength/springiness is needed in thin sheet, strip, foil or drawn wire and forming is minimal. Yield strength is 230 MPa in M versus 420 MPa in H.
