Grade 7 is commercially pure titanium with 0.12 to 0.25 wt% palladium per ASTM B265, UNS R52400, Werkstoff 3.7235. Strength matches Grade 2 at 345 MPa minimum tensile, so the palladium buys corrosion performance in reducing acids rather than mechanical properties. Grade 7 titanium is commercially pure titanium with a small palladium addition. ASTM specifies […]

Two decisions make or break a titanium weld: choosing the right ERTi filler wire for the base grade, and keeping oxygen out of the weld until it has cooled. Titanium is welded with filler wire classified under AWS A5.16, where each ERTi number maps to a base titanium grade. Pick the filler to match the

Choose a titanium forging grade by the part’s job. Grade 2 suits flanges, valve bodies and corrosion-equipment forgings; Grade 5 (Ti-6Al-4V) is the high-strength choice for forged discs, rings and blocks; Grade 7 and Grade 12 handle aggressive acids and hot brine; Grade 23 (ELI) is for fracture-critical and medical-related forgings. Forgings are made to

Choose a titanium tube or pipe grade by service first, then by strength and form. Grade 2 seamless tube is the default for heat exchangers, condensers and seawater; Grade 7 and Grade 12 handle reducing acids and hot brine; Grade 9 (Ti-3Al-2.5V) is the high-strength choice for hydraulic lines, aerospace tube and bicycle frames. Decide

A titanium plate or sheet quotation needs more than the grade. State the grade, the ASTM or ASME standard, thickness, width, length, tolerance, surface condition, supply condition, inspection scope and certificate package in one RFQ. This checklist gives engineering and purchasing teams the exact fields a supplier needs to quote titanium sheet and plate without

Choose a titanium plate or sheet grade by corrosion environment first, then the strength the part needs, then budget. Grade 2 is the corrosion default for tanks, heat exchangers and chemical equipment; Grade 5 (Ti-6Al-4V) is the strength choice for structural and aerospace plate; Grade 7 and Grade 12 handle aggressive acids and hot brine;

A titanium bar quotation cannot be reviewed from the alloy name alone. State the grade, the ASTM or AMS standard, the size, tolerance, surface condition, supply condition, inspection scope and certificate package in one RFQ. This checklist gives engineering and purchasing teams the exact fields a supplier needs to quote titanium round, flat, square or

Grade 2 bar is the usual starting point when corrosion service, forming or welding drives the choice. Grade 5 bar is the higher-strength route for loaded machined parts. The drawing, service environment, supplied condition and governing standard decide between them, so I stop an RFQ that names only ASTM B348 and ask for the missing

Titanium bar machines predictably when you start from annealed stock in the right grade, run sharp carbide at a controlled speed, and never let the tool rub. Titanium conducts heat at roughly one sixth the rate of steel, so heat piles up at the cutting edge, and a feed rate that is too low work-hardens
