Product Description

Product name:Titanium Beta 21S UNS R58210 alloy sheet

Titanium Beta 21 S (Timetal 21S) is one of the beta titanium alloys which was developed as an oxidation-resistant aerospace material and as a matrix for metal-matrix composites. Titanium Beta 21 S (Grade 21) offers the good formability and weldability of a beta alloy, but with greatly improved oxidation resistance and creep strength. The composition of Beta 21S is Ti-15Mo-2.7Nb-3Al-0.2Si, designed to improve corrosion resistance with molybdenum and niobium working together to raise corrosion resistance to very high levels. Beta-titanium alloys show a reduced Young's modulus compared to pure titanium or Ti-6Al-4V, and can be composed completely from biocompatible elements making it a great choice for some medical applications.

Beta Titanium has strength & modulus of elasticity ratios almost twice those of austenitic stainless steel, larger elastic deflections in springs, and reduced force per unit displacement 2.2 times below those of stainless steel appliances.
Grade 21 Titanium has one of the lowest hydrogen uptake efficiency levels of any titanium alloy. It combines high strength, high corrosion resistance, and fracture toughness making it an ideal candidate for orthopedic implants, deep sour oil wells, geothermal brine wells, aerospace honeycomb, aerospace fasteners, and aerospace engine applications.

COMMON APPLICATIONS FOR TITANIUM GRADE 21

• High resistance to aircraft hydraulic fluids
• Used in warm airframes or engine structures
• Structural Honeycombs
• Fasteners
• metal matrix composites
• welded and seamless tubing
