Home > Welded Tubes > ASTM B338 B862
Ultimate corrosion resistance with unmatched strength-to-weight ratio
Titanium is not chosen to save money — it is chosen to eliminate failure.
ASTM B338 / B862 titanium welded tubes are specified where stainless steel, duplex, and even nickel alloys struggle to deliver long-term reliability.
INOX STEEL INDIA supplies project-grade titanium welded tubes engineered for critical service environments.
Titanium welded tubes are manufactured from titanium strip or plate using high-purity inert-gas welding (TIG / Plasma) under controlled environments.
Covered by:
Grade 1 — Maximum Formability
Highest ductility, excellent corrosion resistance, used in chemical processing & low-pressure systems
Grade 2 — Industry Standard (Most Popular)
Best balance of strength & corrosion resistance, dominant grade for condensers & heat exchangers
Grade 5 (Ti-6Al-4V)
Very high strength, used in aerospace & high-stress components
Grade 7
Pd-stabilized titanium with exceptional crevice corrosion resistance
Grade 9 & Grade 12
Special purpose alloys for moderate strength and hot brine environments

B338 covers seamless & welded tubes; B862 covers welded titanium tubes only. Titanium is immune to seawater corrosion and has a very long service life. Grade 2 is the most widely used for heat exchangers and condensers. Yes—BV, DNV, TUV available. What is the difference between ASTM B338 and B862?
