A Titanium Grade 12 Sheet is a flat piece of titanium alloy that has small amounts of molybdenum and nickel. This alloy is resistant to crevice and pitting corrosion, even in places with a lot of chloride, according to standards like ASME SB 265 Titanium Alloy GR.12 Sheet. International standards also refer to this material Ti Alloy UNS R53400 Sheet and Titanium 3.7105 Sheet.
The alloy chemistry about 0.2–0.4% molybdenum and 0.6–0.9% nickel adds strength and improves performance at higher temperatures. Titanium Grade 12 sheets can handle stress well without adding too much weight. They have a yield strength of about 380 MPa and a tensile strength of about 550 MPa. Limits on contaminants in oxygen, carbon, nitrogen, and hydrogen stay low, which helps keep the toughness and quality of the weld.
These sheets are referred as Ti Gr 12 Cold Rolled Sheets, which have a smooth finish and tight thickness control, or as Titanium Grade 12 Hot Rolled Sheets, which are better for heavier sections where strength is important. Standard widths range from 1000 mm to 1800 mm, while lengths can go up to 6000 mm, with custom cuts available. This flexibility makes them easy to fit into many designs.
Titanium Grade 12 stands out for its balance of corrosion resistance, weld ease, and strength-to-weight ratio. It also performs well at low temperatures and resists attack from harsh media. Because of this mix, engineers often choose it over pure titanium grades when service conditions are demanding.
These sheets see wide use across aerospace, chemical processing, marine, and pressure vessel work. You will find them in airframe parts, heat exchangers, reactors, storage tanks, ship components, offshore units, and hydromet systems. Manufacturing starts with alloy melting and slab casting, followed by forging or rolling. Hot rolling forms an alpha case that is later removed by pickling. Cold rolling and annealing refine thickness, strength, and corrosion resistance.
All supplied sheets undergo strict testing before dispatch. Checks include chemical analysis, hardness, flattening, flaring, PMI, pitting resistance, and intergranular corrosion tests. Each order is backed by material test reports and third-party inspection papers. Sheets are packed in wooden pallets or cases to avoid damage and surface marks during transit. Parag Metal is mentioned here once as a trusted Titanium Grade 12 Sheet Supplier, Titanium Grade 12 Sheet Stockist, and Titanium 3.7105 Sheet Dealer serving global markets.

Titanium Grade 12 sheets under ASTM B265 contain controlled limits of carbon (0.08% max), nitrogen (0.03% max), oxygen (0.25% max), and hydrogen (0.015% max). Iron stays low at 0.30% max, while nickel (0.6–0.9%) and molybdenum (0.2–0.4%) give the alloy its strength and corrosion resistance. This balance is what defines ASME SB 265 Titanium Alloy GR.12 Sheet quality.
ASTM B265 Titanium GR 12 Sheets are available in 0.5 mm to 100 mm thick. Widths can be as wide as 2000 mm and lengths are given based on what the project demands. You can easily choose between cold rolled and hot rolled options based on your needs for finish and strength.
Common finishes include mill finish, polished, pickled and passivated (PP), and BA for Ti Gr 12 Cold Rolled Sheets. These finishes help match surface needs for corrosion control, weld prep, or visual use.
Titanium Grade 12 sheets offer a hardness up to HB 170, minimum yield strength of 345 N/mm², and tensile strength of at least 480 N/mm². Elongation reaches 18%, with a modulus of elasticity around 105 kN/mm². These values support use in pressure and load-bearing parts.
Titanium Grade 12 sheets are widely used in chemical plants for reactors and heat exchangers, in marine systems for offshore platforms and seawater units, in desalination plants, and in aerospace structures. Their corrosion resistance and steady strength make them a reliable choice in harsh service.
