he selection of the suitable alloy should not be based on individual criteria, but on as comprehensive as possible a consideration of the various requirements, so as to reach the right decision for the particular application.

1.4301 (vhi 304)
1.4301 is a versatile alloy. Usable at temperatures up to 700 °C - 750 °C, 1.4301 has good temperature and corrosion resistance. This alloy is highly suitable for use at constant temperatures. Major temperature fluctuations can cause or increase embrittlement phenomena.

1.4828 (vhi 309)

1.4828 has a relatively high chromium content with a low nickel component. With its low nickel content, this alloy is suitable for use where sulphur attack is to be expected. 1.4828 has a good tensile strength and is suitable for use at temperatures up to 1000 °C. Due to this composition, 1.4828 should not be used in cyclically operated facilities, as it is sensitive to sigma phase embrittlement. 1.4828 is highly suitable for use at continuous high temperatures.

1.4845 (vhi 310)

1.4845 has the same properties and technical data as 1.4841, but has one great advantage in relation to sigma phase embrittlement. Due to the much lower silicon content, the sigma phase separation quantity is reduced.

1.4862 (vhi 4862)
1.4862 is the suitable alloy for anchors to be used at temperatures up to 1150 °C, particularly under strongly carburising or nitriding conditions. With good tensile strength, the composition of this alloy protects it fully from formation of the sigma phase, and it can therefore also be used in cyclically operated facilities.
