Titanium VT1-00 FORGED-ANN vs VT1-00-HR

Titanium · VT1-00 temper comparison

VT1-00 FORGED-ANN and VT1-00-HR are two conditions of the same titanium grade, VT1-00: FORGED-ANN (forging / ring, annealed) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Both yield at about 235 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (forging / ring, annealed versus hot rolled). For most parts the choice follows the drawing's specified condition; ask for the one your standard calls out.

VT1-00 FORGED-ANN vs VT1-00-HR — frequently asked

What is the difference between VT1-00 FORGED-ANN and VT1-00-HR?

VT1-00 FORGED-ANN and VT1-00-HR are two conditions of the same titanium grade, VT1-00: FORGED-ANN (forging / ring, annealed) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Both yield at about 235 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (forging / ring, annealed versus hot rolled).

Which condition does FabDigit quote by default, FORGED-ANN or HR?

M is the default VT1-00 condition in the FabDigit quote flow (neither FORGED-ANN nor HR). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
