Grade 2 is the grade you specify when a part has to survive a medium. Grade 5 is for parts that carry load. Once you know which of those two duties governs, the grade is close to settled, and the remaining work is product form, condition and documents. Grade 2 is commercially pure titanium, UNS […]
Grade 5 and Grade 23 are the same Ti-6Al-4V alloy, but Grade 23 is the extra-low-interstitial (ELI) version, with tighter oxygen and iron limits. Grade 5 is slightly stronger (895 MPa minimum tensile against 828 MPa for Grade 23) and cheaper. Grade 23 trades that small amount of strength for substantially higher fracture toughness, better
For seawater piping, 316L stainless steel is the wrong default. Its pitting resistance is too low for chloride immersion, so it pits and crevice-corrodes, usually at welds, deposits and stagnant zones. The two materials that actually survive seawater are copper-nickel and titanium. Copper-nickel (90/10 and 70/30) is the proven, biofouling-resistant choice for moderate-velocity piping. Titanium

In chemical processing, the grade is decided by whether the medium is oxidizing or reducing. Grade 2 (UNS R50400) handles oxidizing acids, wet chlorine, chlorides and most organic acids very well. For reducing acids such as hydrochloric and dilute sulfuric, especially hot, move to Grade 7 (UNS R52400), whose palladium keeps titanium passive where Grade

For most ambient seawater service, Grade 2 (UNS R50400) commercially pure titanium is the default, because titanium forms a stable passive oxide film that does not corrode in chloride water. When the service runs hot (roughly above 70 to 80 C), involves tight crevices, or carries concentrated brine, move up to Grade 7 (UNS R52400)

Titanium Grade 2 handles oxidising and neutral chloride service. Grade 7 adds 0.15% palladium for reducing acids. Grade 12 raises the crevice threshold in hot brine. For unalloyed titanium the TIMET corrosion manual puts the onset in sharp crevices in near-neutral brine at about 93 °C (200 °F), with attack not likely below 70 °C

Titanium anodes for impressed current cathodic protection (ICCP) are MMO coated titanium electrodes that deliver protective current to a buried or submerged structure without dissolving. They have largely replaced consumable anodes in ICCP because the titanium substrate is dimensionally stable and long-lived. This guide covers coating choice by environment, the forms used, and what to

An MMO coated titanium anode is a titanium substrate coated with a mixed metal oxide layer, also called a dimensionally stable anode (DSA). The titanium base gives mechanical strength and corrosion resistance, and the oxide coating carries the electrochemical reaction without the anode dissolving. This guide covers the coatings, substrate, forms and applications, and what

Titanium wire is drawn from 0.01 mm to 6.35 mm on spools, 0.8 mm to 12 mm in coil, and 0.8 mm to 6.0 mm in straight cut lengths up to 6,000 mm. General wire is ordered to ASTM B863, welding filler to AWS A5.16, and implant wire to ASTM F136 or F67. Titanium wire

Titanium welding wire is a filler metal used to join titanium by gas tungsten arc welding (GTAW or TIG) and gas metal arc welding (GMAW or MIG). AWS A5.16/A5.16M classifies titanium and titanium-alloy electrodes and rods primarily by electrode chemical composition and also addresses general requirements, testing, packaging and application guidance. This guide explains common
