Cr-V: Chromium-vanadium alloy steel offers higher strength and toughness than carbon steel, making this a desirable material for manufacturing high quality hand tools such as wrenches, ratchets, sockets, etc. This alloy has great oxidation, corrosion, and abrasion resistance properties.
Cr-Mo: Chromium-Molybdenum alloy steel, also known as chrome-moly or cro-moly, has superior impact resistance than Cr-V, a property that makes it an ideal material for impact sockets, high torque screwdrivers, rachet head components, breaker bar heads and more. The addition of molybdenum gives this alloy the ability to absorb percussive impact better than Cr-V; it also outperforms Cr-V in strength and toughness, but it is more expensive, which is why is reserved for impact rated and high-end tools.
S2 Steel S2
S2: S2 steel is an alloy designed to resist breakage by shock; it presents high impact and vibration resistance. S2 is known for its optimum mechanical wear resistance, long life, strength, and toughness; which is why it is our choice for bits and drivers.
Stainless Steel SS440
Stainless Steel 440: Stainless steel offers outstanding corrosion resistance and mirror-like finish, requiring minimal care. This type of steel is highly wear resistant and dependable. It is widely used for making scrapers, shears, trim and upholstery tools, as this type of tools favor high hardness blades with optimal edge retention.
It is often thought that “true” stainless steel is non-magnetic, however, this is a common misconception. There are different families of stainless steel: austenitic, ferritic, and martensitic; out of these three, only austenitic stainless steels can have non-magnetic properties and it is due to the addition of nickel to their composition.
