Part One: Ferrous Sand Casting Materials
Steel
Cast steels offer a range of beneficial properties. It can provide sand-casted products with high tensile strength and high resistance to wear. It is a suitable material for applications where extreme conditions and temperatures are present. The steel Sand Casting Materials include:
- Carbon Steel: Al, A2, A3, A4, A5 ,A6
- Stainless Steel: SS304 and SS306. These two grades feature castability, corrosion-resistant and weldability characteristics.
- High Tensile Steel: BT1, Bl2 and BT3
Grey Iron (BS EN1561)
Grey Iron is One of the most widely used cast irons. It is widely used in heavy-duty industrial components, household appliances. This metal has excellent resistance to corrosion, is of high strength, and is easily machinable.
The sand casting gray iron grade is
- Grade 150
- Grade 200
- Grade 250
Ductile Iron
Ductile cast iron is also known as Spheroidal Graphite Iron or SG. Ductile Iron is used to produce parts that have to carry heavy loads or resist impacts. In some applications, it is also a suitable substitute for malleable iron.
The sand casting grade ductile iron is
- Grade 400/15
- Grade 450/10
- Grade 500/7
