The difference between Cast Iron Exhaust Manifold And Cast Steel Exhaust Manifold

When you need a new exhaust manifold, your parts supplier may ask you that you want 'Cast Iron' or 'Steel'? Would you be able to answer this right away? 

Here is some information that can help you make a decision.

CAST IRON:

1.The material is inexpensive and easy to work with. 

2.Material is durable and can have a long life.

3.It is more weight than steel.

4.Requires special tools for production, but easier for mass production.

CAST STEEL:

1.Steel with different options, mild steel or stainless steel.

2.Mild steel has a 'low degree to thermal expansion' and is an excellent choice for flanges.

3.Stainless steel is stronger and more corrosion resistant than mild steel, but costs more.

The decision to replace your exhaust manifold and what type of replacement to go with also depend on many factors. You should consider from actual situation, or you can come to ask our engineer for assistance.
