Measures to Improve Impact Toughness of Duplex Stainless Steel Pipe Fittings

DataTime:[2017-9-3]

Generally, the measures taken to improve the impact toughness of duplex stainless steel fittings are nothing but the following:

1. reduce the carbon content of dual phase steel pipe fittings;

2., increase the ratio of manganese to carbon (Mn/c);

3. adding alloying elements, such as Ni, Cr, Mo, etc.;

4. reduce sulfur content;

5. reduce the sulfur content inclusion in duplex stainless steel pipe fittings and improve the morphology of sulphide inclusion;

6., the use of furnace refining process;

7. improved heat treatment

In the above measures, the improvement of heat treatment is the first choice that should be paid attention to, because:

1. does not result in significant adjustments in the casting process;

2. do not have to add equipment;

3. production costs are increasing little.
