Grade 27 Ti-0.1Ru (UNS R52254) is an industrial pure titanium plate/strip with a trace amount of ruthenium added. You can think of it as a "Grade 7 titanium material with low-cost ruthenium replacing high-cost palladium". It maintains excellent corrosion resistance while significantly reducing raw material costs, making it a highly cost-effective material in the field of chemical anti-corrosion. Core characteristics and composition: Grade 27 is essentially industrial pure titanium Grade 1 with 0.08% - 0.14% ruthenium added. This special microalloying gives it the following advantages:
Extremely cost-effective: The price of ruthenium is only about 15% - 20% of that of traditional corrosion-resistant titanium materials (such as palladium used in Grade 7), and using Grade 27 instead of Grade 7 can save a lot of material costs.
Strong corrosion resistance: In weakly reducing acidic environments (such as hydrochloric acid, sulfuric acid) and high-temperature chloride brines, its resistance to crevice corrosion and pitting corrosion is very similar to that of expensive Grade 7/16 titanium alloys.
Excellent processability: Its mechanical properties (strength, ductility) are comparable to those of Grade 2 titanium, with higher strength than Grade 1, and it is easier to form and weld than palladium-containing titanium materials.
Common product forms and standards: When supplied as plates or sheets, Grade 27 usually follows the following standards:
Product standard: Mainly conforms to ASTM B265 (Standard Specification for Titanium and Titanium Alloy Strip, Sheet, and Plate)
Form and size: In addition to plates, it is also often supplied in the form of coils, strips, or foils, with thickness ranging from extremely thin 0.001 inches to several millimeters, meeting different industrial processing needs.
Main application scenarios: Due to its excellent corrosion resistance and cost advantage, Grade 27 plates and coils are widely used in:
Chemical processing: Manufacturing storage tanks, reactor linings, towers, and piping systems that come into contact with reducing acids (such as hydrochloric acid, sulfuric acid).
Marine engineering: Used in desalination equipment, offshore oil platforms, and other corrosion-resistant components, effectively resisting chloride corrosion in seawater.
Energy and environmental protection: Used as structural materials in flue gas desulfurization systems, electroplating equipment, and various industrial processes that require the use of strong corrosive chemical media.
