Cost-effective, durable, and tough, Boron grades significantly reduce steel hardening costs for moldboard plows, disc harrows, and cultivators — while increasing hardness and toughness. They are compelling replacements for carburized, triple-layered cladding, B27/B30, and high alloy tool steels for tillage implements.
Boron steel for tillage applications is engineered to harden through, so you skip the case-hardening process entirely. Carburizing ties up a furnace for 12 to 24 hours, involves hazardous chemicals, and carries a real energy and carbon cost. Boron steel needs a single quench. Toughness comes out higher than carburized surfaces, and the risk of quench cracks drops substantially.
Triple-layer cladding is faster than carburizing, but the trade-off shows up in low toughness and a hardened layer that's tough to drill or cut in the workshop. Boron steel for tillage keeps the hardness manufacturers need without that processing penalty, and a single engineered steel costs less than a multi-layer cladding process. Shops handle it on standard equipment.
High-alloy tool steels do offer through-thickness hardness, which matters for tillage parts that wear down past their surface layer. Boron steel delivers that same through-hardness at a better price point, with improved toughness against stone and rock impacts and far fewer quench cracks. No special workshop procedures required. You get the hardness profile without the premium or the processing headache.
Boron steel for tillage suits any implement that has to cut, turn, or break soil while surviving repeated stone impacts. The five applications below are where manufacturers get the strongest return.

Economical, ≈59 HRC through-hardness, good toughness, excellent workshop properties. Tillage implements such as moldboards operate in high-wear environments, especially after the harvest. The wearing becomes even more aggressive if there is frost and crop residue. Moldboard plow manufacturers, therefore, search for high hardness steels to reduce wear, plus good toughness to resistant impacts against stones and small rocks.

Compared to conventional B27/B30 steel, SSAB Boron 45 delivers 4 to 5 HRC higher hardness that goes all the way through its thickness. It can be used with a variety of common heat treatment processes, including press hardening and hot forming – without quench cracks.
