Grade 250 steel
What does it mean by grade 250 steel?
It is a carbon steel flat product normally in plate or coil form with a minimum yield strength of less than 250. It is one of the most commonly used steel grades.
What are the benefits of grade 250 steel?
- Cost-effectiveness- it is probably one of the basic mild steel with lower cost.
- Weldability- Grade 250 mild steel is easy to weld.
- Formability- Medium tensile and yield strength with good elongation makes this material easy to form.

This steel is carbon steel, rather than alloy steel, as it does not contain large amounts of elements – like chromium or molybdenum. Known as ‘low carbon steel’, it typically has from 0.05% to 0.25% carbon content by weight. (It would be classified as cast iron if any more carbon were added.)
With low levels of both carbon and other alloying elements, mild steel has a number of distinct characteristics that make it a beneficial choice of material for a range of applications.
