Tantaline ® treatment uses high-end Chemical Vapor Deposition techniques to deposit a uniform, diffusion bonded layer of corrosion resistant tantalum onto very intricate shapes and smaller sizes of fittings while maintaining critical tolerances. Tantaline® treated fittings offer better corrosion resistance than austenitic stainless steels which cannot fight stress corrosion, chloride attack, and especially sulfide cracking. The metallurgical properties of the tantalum surface combined with the uniform and conformal CVD layer results in superior acid resistant fittings that have excellent compatibility in most aggressive acids and can be offered with economical pricing and short lead-times.
