What is White Oak GREEN?
White Oak GREEN is White Oak in the GREEN condition — pick for steam bending, wet cooperage stock, or timber-frame work that will season in place. White Oak GREEN has a tensile strength of 60 MPa (8.7 ksi), stronger than 66% of natural material grades. Elongation at break is 2% and the elastic modulus is 9.8 GPa (1.42 Msi). White Oak GREEN has a density of 1 g/cm³ (0.0361 lb/in³), heavier than 79% of natural material grades. KD12 is the default condition FabDigit quotes; GREEN is available on request or by drawing note.

Working with White Oak GREEN
Is White Oak easy to machine?
Cuts and turns well with carbide tooling at moderate feed, but silica/tannin content dulls HSS quickly and ring-porous grain tears out — use sharp 20–25° rake knives and back-up on cross-cuts.
Can White Oak be welded?
Not weldable; joined by PVA/PUR/epoxy adhesive or mechanical joinery — bond within hours of surfacing since tannin-rich, oily faces reduce glue wetting.
Can White Oak be formed, bent or molded?
Excellent steam-bending timber (green or freshly steamed at ~100 °C, 1 h per 25 mm); air-dry only after clamping to a form, and allow ~10 % tangential / 5 % radial shrinkage green-to-oven-dry.
What surface finishes work on White Oak?
Sands to 180–220 grit and takes stain, oil and film finishes well; fill the open earlywood pores for gloss, and use stainless or hot-dip galvanized fasteners since iron reacts with tannin to leave black stains.

White Oak GREEN — frequently asked
What is White Oak GREEN used for?
White Oak GREEN is typically used for furniture, flooring, cabinetry, wine/whiskey barrels and boat building. In short: rot-resistant structural hardwood; best steam-bending hardwood; liquid-tight cooperage timber.
What is the tensile strength of White Oak GREEN?
White Oak GREEN has a typical tensile strength of 60 MPa (8.7 ksi) — stronger than 66% of natural material grades. Strength varies by condition: see the 4 listed tempers.
Is White Oak GREEN easy to machine?
Reasonably — machinability is rated good (55/100, worse than 91% of natural material grades). Cuts and turns well with carbide tooling at moderate feed, but silica/tannin content dulls HSS quickly and ring-porous grain tears out — use sharp 20–25° rake knives and back-up on cross-cuts.
Can White Oak GREEN be welded?
Not weldable; joined by PVA/PUR/epoxy adhesive or mechanical joinery — bond within hours of surfacing since tannin-rich, oily faces reduce glue wetting.

Can White Oak GREEN be formed, bent or molded?
Excellent steam-bending timber (green or freshly steamed at ~100 °C, 1 h per 25 mm); air-dry only after clamping to a form, and allow ~10 % tangential / 5 % radial shrinkage green-to-oven-dry.
What is the maximum service temperature of White Oak GREEN?
White Oak GREEN is rated for continuous use to about 60°C (140 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
