Feature:

Due to the addition of titanium, it has better resistance to intergranular corrosion and high temperature strength.

Effectively controls the formation of chromium carbide.


Application:

It is used in field open-air machines for chemical, coal, and petroleum industries with high resistance to intergranular corrosion, heat-resistant parts for building materials, and parts with difficult heat treatment, such as:

1. Petroleum waste gas combustion pipeline

2. Engine exhaust pipe

3. Boiler casing, heat exchanger, furnace components

4. Dust-proof parts for diesel engines

5. Boiler pressure vessel

6. Chemical transport vehicle

7. Expansion joint

8. Spiral welded pipe for furnace pipe and dryer

9. Aircraft
