Measures to Improve Impact Toughness of Duplex Stainless Steel Pipe Fittings

by yane Yang Sales Manager

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.
