Shear Blade

DESCRIPTION OF GRADES

AKI-1 is a Standard Carbon alloy tool steel, used in manufacturing of shear blades for maintenance-type shearing equipment. This low-cost alloy is generally used when the life of the blade is not a major concern.

AKI-2 is a Mid-Range alloy tool steel, which provides the highest degree of toughness, recommended for shearing of mild steel 3/8" and thicker. This durable , "shock resistant" material has increased wear ability over and above that of our AKI-1. When shearing stainless steel, it is  recommended that you shear no more than 50% of the machine's rated cutting capacity.

AKI-3 is a High Carbon, High Chrome (HCHC) alloy tool steel containing sufficient amounts of chromium to provide excellent wear resistance on lighter gauge

shearing. This wear-resistant tool steel is designed for shearing no more than 3/8
 thick mild steel on hydraulic shears. When using this grade on mechanically controlled shears, the maximum shearing capacity is no more than 1/4" Thick mild steel. When shearing stainless steel, it is recommended that you shear no more than 50% of the machine's rated cutting capacity.

AKI-4 is a true AISI M-2 High Speed Steel (HSS), usually used in the manufacturing of single edge shear blades when the customer requires maximum blade life between sharpening under light capacity shearing conditions. This tool steel contains large percentages of molybdenum, which increases wear resistance, thereby maximizing the number of cuts between sharpening.
