Key Steel is widely used for many general engineering applications. Typical key steel applications include taper, gibhead, plain and parallel keys. As a bright drawn steel bar it is uncommon to harden key steel. In its supply condition key steel has an approximate tensile strength of 500 to 700N/mm2.
What steel is key steel?
medium carbon steel
A bright drawn steel in square and rectangular bar, key steel is an unalloyed medium carbon steel with reasonable tensile strength. It is supplied bright drawn in flat and square sections conforming to the specification requirements of BS46 and BS4235.
What is key steel made of?
Typically, key stock is made from carbon steel or stainless steel, but can also be made from aluminum, brass, copper, monel, and even nylon, all with varying material grades. AISI 316 stainless is also available for marine applications.
Is key steel stainless?
Keysteel 080M40 (EN8). Werkstoff C45 +C. A2 303/304 grade stainless steel.
Is key stock hardened?
In North America, a lot of ANSI key stock is made from C1018 a low carbon general purpose steel with good case-hardening qualities because it is less expensive, while in Europe it is made from C1045, a medium carbon steel that can be through-hardened to produce higher strength properties.
Is key steel magnetic?
Only car keys with nickel, steel, or iron in them will be magnetic.
Is key steel hardened?
The high carbon content of the key steel means that it can be hardened. As supplied however, the steel is machinable. On hardening and tempering a hardness of up to Rockwell C55 can be obtained.
What is key stock steel?
Key Stock, or bright steel, is a general term for a stock of square or rectangular bars 12 inches or longer in length from which machine keys are produced. Key Stock is cold drawn to exacting tolerances with sharp corners, perpendicular and parallel sides, and smooth, bright surface finishes.
Which key is used in automobile shaft?
Explanation: Normally in Automobile shafts Woodruff key is used.
What is the best material for shaft?
The material used for ordinary shafts is mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. Shafts are generally formed by hot rolling and finished to size by cold drawing or turning and grinding.
What is undersized key stock?
Undersize key stock is key stock 12 inches or greater in length with an actual size slightly smaller than a specified size while remaining within an acceptable tolerance range.
What is a shaft key?
The shaft Key is a small metallic component that plays a major role in connecting the shaft and hub with another rotational component such as gears, bearings, etc. Shaft keys are always parallel to the axial of the shaft. There are several types of shaft keys.
What is a key stock?
An Overview of Key Stock
The term key stock is a term that generally refers to square or flat steel (key) that has been precision drawn and processed to function as a locking torque mechanism in connecting a shaft to a gear or pulley.
Are Keys brass?
Keys are typically made of brass or a nickel-brass mixture, and the pins in a lock are also made of brass. Over years of use, keys and pins do wear down.
Are Keys ferrous?
Wood was replaced with bronze and iron. Today keys are made out of nickel silver, brass, and steel.
Are car keys brass?
The majority of aftermarket keys available today are brass. Some are plain brass and have the classic brass color. Most of the shiny bright silvery keys you see are actually nickel-plated brass. Once these are cut, you’ll see the brass color on the inside.
How do you remove key stock?
Place the assembly over the key, and then thread the bolt into the shaft as far as it will go. Spin the nut downward against the block. Then use a wrench to apply enough force on a nut to remove the key from the shaft. If you apply enough downward movement, the key will be extracted.

How much torque can a keyway handle?
The limiting pressure point of a keyed shaft is the keyway side of the male shaft, provided the proper key material is selected. Thus, 270 Nm is the maximum torque that can be transmitted before the 19 mm diameter keyed shaft plastically deforms.
What is saddle key?
Definition of saddle key
: a key for securing a member to a machine shaft that fits into a keyway in the secured member and is concave to grip the shaft by friction compare flat key, sunk key.
What is a key and keyway used for?
What are Keys & keyways? A key and the keyways make up a Keyed joint to secure the hub and the shaft to prevent relative movement between a power transmitting shaft and an attached component. For example, Gear drives, Pulleys or Sprockets are connected securely using keys to the power transmitting shaft (Figure 1).
