15HSND Application:

Steel grade 15HSND is used for the manufacture of different welded steel structures and parts that work in the temperature range from -70 to 450 ° С, High strength and corrosion resistance are required.

The surface of 15HSND steel plate should not have harmful defects such as bubbles, scars, cracks, folding, inclusions and pressing into the iron oxide scale that affect the use
