Related QuestionsWhat are the requirements for NSF/ANSI Standard 61 and lead?
NSF International : Water Distribution : Frequently Asked Qu...NSF/ANSI Standard 61 requires all metallic products and components to be evaluated for the leaching of lead as well as other metal contaminants. Metallic pipe, fittings, valves, and other mechanical devices are all tested with two specially formulated waters. One is pH 5 and another pH 10. The pH 5 test water is especially aggressive for copper, chromium, nickel, and antimony.

Related QuestionsWhat makes stainless steel "stainless"?
Frequently Asked Questions about Steel for Wire ProductsCompared to plain carbon steel, stainless steels (there are more than 300 grades) contain at least 12% Chromium - a metal that is intrinsically corrosion resistant. Because of this alloying, stainless steels form a tightly-adherent and protective oxide layer which is so thin that the metallic coloration of the underlying steel is visible. The oxide layer that forms in ambient environments on plain carbon steels (i.e.

Related QuestionsHow do I weld stainless steel?
Frequently asked questionsThis is not a skill everyone can acquire. Thin stainless can be spot-welded which is suitable for the combustion chamber and case. The NGV assembly will require MIG or TIG welding. TIG sets are expensive and it may be necessary to find a specialist welder used to welding stainless steel to do the welding for you. Modern engines employ a casting for the NGV which is more stable during natural heat cycling.
Related QuestionsStainless SteelStainless steels are a family of steels that are resistant to corrosion (rusting) and elevated temperature. They must contain at least 10.5 % chromium. The chromium reacts with the oxygen in the air to form an invisible, protective chrome-oxide surface layer. This layer helps to prevent “staining” (rusting) of the surface. This does not mean that stainless steel will never rust. There are many different stainless steels with unique chemical compositions.Related Questions
