15B30 is a carbon-boron steel produced in accordance with the American Iron and Steel Institute (AISI) and the Society of Automotive Engineers (SAE) chemical composition limits. 15B30 is a carbon steel with boron added to enhance the hardenability, strength and wear resistance compared to plain carbon steels of the same carbon content.
SSAB supplies 15B30 in the as-rolled, non-heat treated condition. 15B30 is vacuum degassed as part of the secondary steelmaking process to reduce the dissolved gasses (hydrogen, nitrogen, oxygen) in the molten steel and promote enhanced cleanliness and improved properties.
Common applications for 15B30 include ground engaging tools and agriculture components such as tiller disks, sweeps and spikes.
