v engine valve                                           [Click here for technical details] Single Metal, 2 Pcs. Construction (Bi-Metal), seat stellited & Tip Hard, stainless steels with or without tuff-triding, Hard chrome on stems.

Materials
A variety of alloys to suit all applications. These include carbon steel, martensitic steel with chrome and silicon, stainless martensitic, stainless austenitic, Inconel and Nimonic.

Engineered Features
One-piece construction for most applications. These OE spec materials are designed to handle the extreme hostile environment of engines at full operating temperatures. On Heavy Duty applications we also offer bi-metallic construction to gain the best properties of two different OE spec materials for thermal resistance (head) and mechanical resistance (stem and tip). Hard chrome-plated stems where required, to reduce stem wear. Stellited seats where required , to avoid corrosion caused by combustion gases. Welded wafer tips to resist friction of dynamic load. Some tips are also stellited.
