Ferrous Metals Flashcards
Learn ferrous metals
Contains 0.3% carbon and is soft and ductile
Mild steel
Contains 0.7% carbon and can be forged
Medium carbon steel
Contains 0.8% - 1.7% carbon and is used mostly for tools
High carbon steel
Contains 0.5 % - 0.7% carbon and is used in suspension springs
Spring steel
Contains 1% boron and forms an alloy
Boron steel
Automotive uses for high tensile steel
Body structure
Light and strong metal
High tensile steel
Does not withstand high temperatures
High speed steel
Contains iron and reacts to magnets
Ferrous metal
Does not react to magnets
Non ferrous metal
Used in gearboxes and steering columns
Magnesium
Lightweight and resists corrosion
Magnesium
Plastic reacts to heat and then sets
Thermosetting
Plastic reacts to heat and can be recycled
Thermoplastics
Used in lightweight body panels and car frames
Carbon fibre
Mechanical bonding is
Using nuts, bolts, studs etc.
Chemical bonding is
Using chemical compounds such as adhesives or tapes
Weld bonding is
Using MIG, TIG and oxy-acetylene
Used to determine thread pitch
Thread gauge
Used to secure wiring harnesses
Cable ties
Used to secure exhaust components
Clamps
Used to secure decals
Double sided tape
Used to secure components near high vibration areas
Lockwire
Used to secure door hinges
Pins
Used to secure automotive trim and on exterior mouldings
Plastic body clips
Used in large diameter holes
Morse taper drill
Used in portable drills
Parallel shank bit
Does NOT use morse taper drill bits
Drill press
Five measurements that can be taken using a combination square
Depth
Flatness
45 degree angle
Inside and outside right angles
Designed to cut external threads on rods
Split die
Used to restore external threads
Die nut
Used in bumper covers
Polyurethane
High strength to weight ratio and high tolerance to heat
Carbon fibre
Heated and then cooled very slowly
Annealing
Heated to annealing temperature then cooled in still air
Normalising
Heated and quenched in water or oil
Hardening
Heating then quenching
Tempering
Heated to 900°C, dipped in carbon, heated again and quenched
Case hardening
Used to secure two components together and is double ended threaded
Stud
Examples of mechanical locking devices
Spring washers Flat washer Speed nuts Tab nuts Split pin
