Assuming you mean a barrel that is for lead pellets, if the barrel is not rifled, steel shot will not damage the smooth barrel. If it is rifled however, steel shot will in fact damage the rifling.
Steel is typically at room temperature, which is around 68-77°F (20-25°C).
Steel typically melts at a temperature range of about 2,500°F to 2,800°F (1,370°C to 1,540°C), depending on its specific alloy composition. Different types of steel, such as carbon steel or stainless steel, can have slightly varying melting points due to their differing chemical properties.

A damascus barrel is a barrel made of damascus steel, which is steel produced by hammering two different steels together. The twist refers to the pieces of steel being twisted while they are hammered, which produces the distinctive pattern on the steel.
