Ferrous Metals
High quality steel for a full range of applications
Material name
- Low carbon steels
Composition
- Contains less than 0.30% Carbon
Properties
- Relatively softer, malleable and ductile, easy to form and weld, relatively cheap
Applications
- Chains, rivets, nails, wire, pipe, machine and structural parts
- High carbon steels
- Contains 0.3-1.7% Carbon
- Higher hardness and wear resistance, fair formability, usually heat-treatable
- Gears, spindles, shafts, crankshafts, axles machine parts
- Tool steels
- Above 0.8% in Carbon
- Even higher hardness but more brittle, usually heat-treatable
- Hand tools, springs, drills, knives, cutting tools and other applications that require higher hardness and tensile strength
- Stainless steels
- Contains at least 10.5% chromium, with or without other elements
- Good corrosion resistance, shiny silver appearance, and good mechanical properties. The Chromium in the alloy forms a self-healing protective clear oxide layer. This oxide layer gives stainless steels their corrosion resistance
- Wide range of applications including culinary uses, cutlery, cookware, food processing applications; surgical tools and medical uses; architectural and construction; automotive and aerospace applications
- Grey Iron
- Contains 2.5-4.0% carbon and 1-3% silicon by weight
- A type of cast iron with a graphitic microstructure, relatively low cost and good machinability, good galling and wear resistance with self-lubricating properties, good corrosion resistance and easy to weld; low tensile strength and ductility
- Common engineering alloy, used for engine blocks, pump housing, valve bodies, heat resisting applications such as cookware, crucible and disc brake rotors.
- Ductile Iron
- Carbon: 3.2-3.60%
- Silicon: 2.2-2.8%
- Manganese: 0.1–0.2%
- Magnesium: 0.03–0.04%
- Phosphorus: 0.005–0.04%
- Sulfur: 0.005–0.02%
- Copper: <0.40%
- Iron: balance
- Superior elasticity, tensile and impact strength, elongation and ductility due to the spheroidal nature of the graphite particles in the material
- Most common applications include ductile iron pipe used for water and sewer lines, as well as automotive components, and structural parts and frames
- White Cast Iron
- Contains carbon content >2% in the form of cementite (Fe3C)
- Low cost, high hardness and abrasion resistance; rather brittle
- Wear surfaces of slurry pumps (impeller/volute), shell liners and lifter bars in ball mills and grinding mills, balls and rings in coal pulverisers etc.
- Manganese Steel
- Contains 12-14% manganese
- High impact strength and resistance to abrasion after hardening
- Mining: cement mixers, rock crushers, tractor treads and other high impact components
- Railway: switches and crossings
- Security: safes, bullet proof cabinets and anti-drill plates
