321 stainless steel round bar

321 stainless steel round bar has the following characteristics:

1. TL exists as stabilized yuanliao, but it is also a hot strength steel. It is much better than 316L in high temperature.

2. It has good wear resistance in organic and inorganic acids with different concentrations and temperatures, especially in oxidizing media. It is used to manufacture linings and transmission pipelines of wear-resistant acid containers and wear-resistant equipment.

3. It is a Ni Cr Ti austenitic stainless steel. Its properties are very similar to 304. However, due to the addition of titanium, it has better grain boundary corrosion resistance and high temperature strength. Due to the addition of titanium, it can effectively control the formation of carbide.

4. The excellent high-temperature stress fracture performance and high-temperature creep resistance stress mechanical properties are better than 304 stainless steel.

Application scope and application field of 321 stainless steel round bar:

It is applied to outdoor machines in chemical, coal and petroleum industries with high requirements for grain boundary corrosion resistance, heat-resistant parts of building materials and parts with difficulty in heat treatment, such as:

1. Petroleum waste gas combustion pipeline

2. Engine exhaust pipe

3. Boiler shell, heat exchanger, heating furnace components

4. Silencing parts for diesel engine

5. Boiler pressure vessel

6. Chemical transport vehicle

7. Expansion joint

8. Spiral welded pipe for gas furnace pipe and dryer
