Titanium Grade 2 Plate Weight
Mass per square metre for titanium grade 2 plate at 4,510 kg/m³ (ASTM B265 / B348 (UNS R50400)). Plate is sold by area, so every figure here is per square metre rather than per metre of length.
At the reference dimensions (w = 1000 mm, t = 10 mm) this section has a cross-sectional area of 10,000.0 mm², giving 45.10 kg/m² (9.24 lb/ft²). Against carbon steel's 7,850 kg/m³ that is -42.5 % — the same section in steel would be 78.50 kg/m².
Plate — formula and derivation
Area of a plate
A = w · t
A = w × t. For plate the useful output is mass per unit area: m″ = t × ρ
Worked through with the default dimensions:
A = w × tA = 1000 × 10A = 10000.0 mm²Per square metre: 10 mm × 1 m² = 0.0100 m³/m²
- w
- Width
- t
- Thickness
Weight follows from the area with no further geometry: m = A × 10⁻⁶ × ρ, where A is in mm², ρ in kg/m³ and m in kg/m. At 4,510 kg/m³ that is 45.1000 kg/m for the reference size above.

Each row is one nominal size. The thickness column drives everything: mass per square metre is thickness × density, so it scales in a straight line.
Imperial sizes

The same plate in every material
Geometry is fixed and only density changes, so this table is the whole material-selection question in one view. Titanium Grade 2 is highlighted. The percentage column is against carbon steel, which is the figure most quotations are built on.

Same geometry throughout, so the only variable is density. Carbon steel is highlighted as the baseline.
A note on using this table for costing: mass is not price. Aluminium is roughly a third of steel's mass here, but per kilogram it costs several times more, so a straight swap rarely saves money — what it buys is reduced load on a structure or a vehicle.
About titanium grade 2
Commercially pure titanium, the workhorse corrosion grade rather than the aerospace high-strength one. Density 4,510 kg/m³ gives it 57 % of steel’s mass with a comparable tensile strength, which is the headline — but titanium’s real advantage in chemical plant is a passive oxide film that survives chlorides, wet chlorine and oxidising acids that destroy stainless. It is expensive enough that the mass change is a secondary concern to the corrosion allowance it lets you remove.

Poor machinability — low thermal conductivity causes heat to concentrate at the cutting edge. Titanium is also combustible as fine swarf.
About plate
Plate is the one product where the customer usually wants mass per unit area rather than per unit length, because plate is priced and handled by the square metre. Reducing thickness by a fraction of a millimetre has an outsized commercial effect: stepping a 6 mm floor plate down to 5 mm removes 16.7 % of the steel on a job that may be measured in thousands of square metres. That is also exactly why plate thickness tolerances are specified separately from the nominal value — a permitted negative tolerance on a nominally 6 mm plate is real money at scale.
Specified as thickness × width × length, plus the tolerance class and whether the pattern is plain, chequer or floor plate.

Frequently asked questions
How much does titanium grade 2 plate weigh?
At the reference thickness of 1000 mm, titanium grade 2 plate weighs 4,510.00 kg/m², which is 923.72 lb/ft². Weight per unit area is thickness multiplied by density, so it scales in a straight line: halve the thickness and you halve the weight.
How is the weight of plate calculated?
Weight is cross-sectional area × length × density. For this shape the area is A = w · t. At the reference dimensions that gives 10,000.0 mm², and multiplying by titanium grade 2's density of 4,510 kg/m³ gives 45.100 kg/m. Nothing is looked up in a table — which is why a non-standard size is calculated just as accurately as a standard one.
Why does titanium grade 2 weigh more or less than steel?
It is lighter than carbon steel for the same section — about 43 % lighter at 4,510 kg/m³. Density is the only variable: the cross-sectional area depends purely on geometry, so a plate of the same dimensions has the same area in every material and the mass simply scales with density. In this case the ratio is 0.5745× carbon steel.
What is the cross-sectional area of a plate?
The area depends only on the dimensions, not on the material, so it is identical whichever material you select: at the reference dimensions it is 10,000.0 mm² (15.5000 in²). That is the number you would enter into a stress or deflection calculation, and it is why changing material on this page never changes the area column.
Does a ti gr 2 plate weigh the same as a ti gr 2 part of a different shape?
No, and the difference is larger than most people expect. At equal nominal size, a square bar is 27.3 % heavier than a round bar, and a hollow section is typically 60–80 % lighter than the solid bar it replaces. Weight follows area, and area changes faster than dimensions do — which is exactly why this needs calculating rather than estimating.
