What is BS EN 16124 – Founding about?
BS EN 16124 is a European standard that discusses the low-alloyed ferritic spheroidal graphite cast irons for elevated temperature applications for founding. Low alloyed ferritic spheroidal graphite cast iron is a cast iron material with carbon mainly present in the form of spheroidal graphite particles, alloyed with silicon to produce a predominantly ferritic matrix and alloyed with molybdenum to improve mechanical properties at elevated temperatures.
BS EN 16124 defines the grades and the corresponding requirements for low-alloyed ferritic spheroidal graphite cast irons for elevated temperature applications. These requirements are specified in terms of:
- Chemical composition: as given for each of the grades
- Graphite form and matrix structure: spheroidal graphite in a predominantly ferritic matrix
- Mechanical properties measured on machined test pieces prepared from cast samples.
Note: BS EN 16124 does not cover technical delivery conditions for iron castings.
Who is BS EN 16124 – Founding for?
BS EN 16124 on founding for low-alloyed ferritic spheroidal graphite cast irons applies to:
- Manufacturer of iron products
- Quality testing personnel
- Suppliers and distributors of cast irons
Why should you use BS EN 16124 – Founding?
Low alloyed ferritic spheroidal graphite cast iron is a cast iron material with carbon mainly present in the form of spheroidal graphite particles, alloyed with silicon to produce a predominantly ferritic matrix and alloyed with molybdenum to improve mechanical properties at elevated temperatures.
As a user, the manufacturer could ensure that the requirements defined in BS EN 16124 are met for the material grade specified in the order. The method of manufacture of low-alloyed ferritic spheroidal graphite cast irons and any heat treatment required to obtain the specified mechanical properties and the microstructure is left to the discretion of the manufacturer.
BS EN 16124 provides the principle which is used for their heat and oxidation resistance properties that classify low-alloyed ferritic spheroidal graphite cast irons.
