What Is the Melting Point of Stainless Steel?

The melting point of stainless steel varies according to the precise chemical makeup of the particular alloy, although the spectrum runs from 1,325 to 1,530 degrees Celsius. Melting range is important in the process of manufacturing to ensure proper melting and casting.

Once stainless steel has left the plant and has been installed, creep strength and oxidation resistance are more important than melting range. For example, Type 304 stainless steel has a melting point between 1,400 and 1,450 degrees Celsius, but the maximum service temperature is much lower: 870 degrees Celsius. The reason for this is that strength and oxidation are affected by factors other than the melting point.
