Soil-engaging tools face simultaneous rock impact and silica sand abrasion. Using certified European-grade 30MnB5 and 38MnB5 micro-alloyed boron steel, automated billet induction heating, and computer-controlled quench-and-temper furnaces, we achieve uniform HRC 48–52 through-hardness—preventing brittle breakage on stones while delivering up to 45% longer field acreage than carbon manganese steel.

Micro-additions of boron (0.002%–0.005%) dramatically increase hardenability at lower carbon equivalents, allowing the entire blade cross-section to achieve HRC 48–52 hardness while retaining fine-grained core toughness that absorbs rock strikes without shattering.
Yes. Custom cold/hot stamping of your brand mark, batch code, and OEM part number is included at standard MOQ, and our CNC laser/punch cells produce 4-bolt, 5-bolt, 6-bolt, square, or round center hubs with zero tooling delay.
