All of our shear blades are crafted from the highest-quality alloys using close tolerance quality control standards. Our “Made in the USA” shear blades provide optimum performance and extended blade life, meaning that you receive more tons per edge, while reducing downtime due to blade changes. Extended blade life combined with less downtime leads to a more productive and profitable production shearing operation.
Our blades are available in single-edge, two-edge, four-edge, and bowtie configurations. Each of these configurations are available in different alloy grades to suit your individual needs. All of our shear blades are thru hardened to ensure consistent hardness; our in-house hardening and tempering furnace can handle shear blades up to 16 feet in length.
We offer the following shear blade grades to cover the most shearing applications possible:
MARK I - Premium grade High Carbon/High Chrome tool steels, providing maximum life between regrinds when cutting mild steel up to .250” thick on mechanical shears. This grade is also ideal for shearing mild steel up to .375” thick on hydraulic shears, due to the lack of impact and a slower cutting action. For shearing stainless steels, most OEM’s recommend that you reduce stated capacities by 50%.
MARK II - Premium grade modified alloy tool steels, providing a maximum number of cuts before dulling when cutting mild steel grades up to 1” thick. These alloys have a high degree of toughness, combined with excellent shock resistance, making them equally suitable for shearing high tensile, heavy cross section steels as well. For shearing stainless steels, most OEM’s recommend that you reduce stated capacities by 50%.
MARK III - Premium grade alloy tool steels for unique situations, such as hot work type applications, where elevated temperatures would have an adverse effect on other alloys. Our technical staff can provide application assistance for these alloys in order to determine the correct alloy and hardness range.
