The steel we use on most of our implements is AR400F. The quality and grade of the steel is a large factor in determining the life of an implement. There is a significant difference in strength between metals as you can see here below.
Yes AR500 has higher abrasion resistance, but AR400 has higher impact resistance.
AR400 is quenched and tempered, through hardened abrasion resistant and corrosion resistant. This specialized plate is designed for applications that demand both wear resistance and impact toughness.
AR400F is an optimal combination of hardness, corrosion and abrasion resistance, formability and weldability.
Understanding why AR (abrasion resistant) steel is optimal for manufacturing an implement.Read more at www.leecosteel.com
