Forged with Hastelloy C-276/C-22/B-2, TongBall valve balls perform excellently in a wide temperature range and highly corrosive environment. The precision processing and polishing techniques for nickel-based alloys endow them with outstanding resistance to pitting corrosion, crevice corrosion and oxidizing acids (such as HCl, H₂SO₄), and they are also resistant to oxidizing salts and chlorine-containing media, ensuring their integrity in chemical and environmental protection systems.
