Titanium Grade 5 Pipe Supplier in India — Ti-6Al-4V (R56400)

Titanium Grade 5 (UNS R56400) is an alpha-beta titanium alloy containing 6% aluminium and 4% vanadium, making it the most widely used titanium alloy accounting for over 50% of all titanium alloy production globally. The Ti-6Al-4V composition provides an exceptional combination of high strength (minimum 828 MPa tensile, 760 MPa yield), low density (4.43 g/cm³ — nearly half of steel), excellent fatigue life, and good corrosion resistance. These properties make it the default choice for aerospace structural components, gas turbine engine parts, medical implants, and high-performance motorsport applications where strength-to-weight ratio is the primary design driver.

Titanium Grade 2 (R50400) is commercially pure titanium with 99.2% Ti content offering moderate strength (345 MPa yield) with excellent corrosion resistance and formability — ideal for chemical processing and seawater applications. Titanium Grade 5 (R56400) is an alloy with 6% Al and 4% V additions that more than doubles the strength (760 MPa yield) while maintaining good corrosion resistance, though it sacrifices some formability and weldability. Grade 5 is chosen when high strength-to-weight ratio is critical such as in aerospace, defense, medical implants, and motorsport, whereas Grade 2 is preferred for corrosion-driven applications like desalination, chemical plants, and heat exchangers where strength requirements are moderate.

In aerospace, Ti-6Al-4V is used for airframe structures, landing gear components, engine compressor blades, and fasteners because it provides steel-equivalent strength at 45% lower weight, withstands temperatures up to 400°C, and resists fatigue in high-cycle vibratory environments. In medical applications, Grade 5 ELI (Extra Low Interstitials) is used for hip and knee replacement implants, spinal fixation devices, dental implants, and bone screws because of its proven biocompatibility, osseointegration capability, corrosion resistance in body fluids, and elastic modulus closer to bone than stainless steel or cobalt-chrome alloys. The combination of high strength, low weight, and biocompatibility makes it irreplaceable in both these critical sectors.

Creative Metal Industries stocks Titanium Grade 5 seamless pipes per ASTM B861 from 1/2 inch to 6 inches NB in schedules SCH 10S, 20S, 40S, and 80S in standard lengths of 4 to 6 metres. Round bars per ASTM B348 are available from 6mm to 200mm diameter in H13 and H14 tolerance grades, supplied in solution treated and aged condition for maximum strength. Welded tubes per ASTM B862 are stocked in OD range 25mm to 114.3mm with various wall thicknesses. All material is supplied with complete mill test certification per EN 10204 3.1 including chemical analysis, mechanical properties (tensile, yield, elongation), microstructure verification, and positive material identification (PMI).

Welding Titanium Grade 5 is significantly more challenging than welding commercially pure grades due to its sensitivity to contamination and tendency toward embrittlement. Ti-6Al-4V requires complete inert gas shielding (argon 99.995% minimum) using trailing shields, backing gas, and enclosed chambers for critical welds to prevent oxygen, nitrogen, and hydrogen pickup above 500°C which causes severe embrittlement and loss of fatigue life. The alloy is prone to formation of hard, brittle martensite in the fusion zone during rapid cooling, necessitating controlled heat input and often post-weld stress relief at 595–650°C for 1–4 hours. Pre-weld joint preparation must be immaculate — only stainless steel brushes, acetone cleaning, and no contact with carbon steel. ERTi-5 filler wire per AWS A5.16 is used, though ERTi-2 may be specified for improved ductility in the weld.

Titanium Grade 5 (Ti-6Al-4V) pipe and bar pricing in India typically ranges from Rs 5,000 to Rs 15,000 per kilogram depending on product form, size, heat treatment condition, and order quantity. Seamless pipes per ASTM B861 and round bars per ASTM B348 in solution treated and aged condition command premium pricing due to complex manufacturing involving vacuum arc remelting, forging, and multi-step heat treatment. Grade 5 is approximately 40-60% more expensive than Grade 2 due to the additional alloying elements (aluminium, vanadium) and stricter processing requirements.
