What This Sector Is Up Against
Exhaust systems are a cost and durability problem at once. The material has to survive condensate, road salt and thermal cycling, and it has to press and weld at line rate. Grade 409 was developed for exactly this, and the rest of the programme covers the hot end where 409 runs out of temperature.
Pain Points
- Carbon steel exhaust components rusting through within a few seasons
- Weld zone corrosion in unstabilised ferritic sheet
- Cracking during pressing when the grade has too little elongation
- Hot end parts that scale where a ferritic grade is at its limit
What Buyers Need
- Titanium stabilised ferritic sheet that welds continuously
- Cold and hot rolled thickness that meets with no gap
- Nickel alloy tubing for the hot end and turbo sections
- Consistent width and length so blanks nest without waste

From Enquiry to Container
Step 1
Confirm the peak and continuous temperature at each section of the system
Step 2
Use 409 for the cold and mid sections and a nickel grade for the hot end
Step 3
Set width and length so blanks nest with minimum scrap
Step 4
Supply in the ordered finish with the mill test certificate
Step 5
Ship by sea from Shanghai in the agreed packing
