    The properties for forgings are typical values for section thicknesses up to 11.81” (300mm) solid or 9.84” (250mm) in an annulus with a minimum bore of 3.94” (100mm).
    As the properties from forgings are very dependent upon the product route and the actual forging ratio, then properties and design are by agreement for other than standard items.

    Zeron 100 Impact Strength

    Zeron 100 has good impact strength. There is no true ductile brittle transition, just a gradual decrease in impact energy as the temperature is lowered. The impact energy varies according to product type and production route. Some typical values are shown in Figure 1 on the following page.
    The impact strength of welded Zeron 100 is slightly less than that of parent metal (See also figure 1). Present data suggests that 30 ft. lbf (40J) is a suitable acceptance criterion for duplex stainless steels and Figure 1 shows that 40J is achievable with all product forms of Zeron 100 down to very low temperatures.
    However, to obtain good impact toughness after welding, a higher level of impact toughness is required in the parent metal. Zeron 100 typically has a Charpy toughness > 70J at -58°F (-50°C).
