Bellows, Connectors & Couplings
Bellows used in Exhaust Manifold are made from AISI Grade 321 Austenitic Stainless Steel Sheet with 4 Plies and 3 Convolutions according to EJMA Standard. This grade of steel contains Titanium which withstands very high temperatures and is less corrosive and prevents premature failure so that Bellows give correct expansion and contraction with satisfactory life cycle.
