Frequently Asked Questions (FAQs)

1. Are lawn mower blades hardened steel?

Yes, lawnmower blades are tempered. Tempering is used to make the blade durable, stronger, and tougher. However, the temperature of doing so often depends on the type of metal. Steel is the preferred metallic material for making lawnmower blades.

2. What are the toughest mower blades?

The E6 blades are the widest, thickest blades offered by USA Mower Blades. E6 blades are 3-inches wide and 0.250-inches thick. These extra-thick blades are heavy-duty and will tackle any lawn with ease. Designed for commercial applications, E6 blades offer unmatched durability and longevity.

3. Are lawnmower blades high-carbon steel?

lawnmower blades are not made of high-carbon steel, but medium-carbon steel at best. So from a lawnmower blade you can make a knife that will act like a lawnmower blade- it will bend instead of breaking and smoosh instead of chipping.
