Grey Iron, SG Iron, Steel & Stainless Steel

Learn more about the types of ferrous castings Majorfax delivers:

Grey iron – up to 5000 Kg

(BS EN 1561 Grades 150,200 & 250)

Grey iron is widely used and lends itself to many applications.  It combines strength and machinability with practicality and competitiveness.

We can also offer alloyed irons such as Ni-Hard and Ni-Resist for resistance to impact and wear.

Spheroidal graphite iron – up to 2000kg

(BS EN 1563 Grades 400/15, 400/18LT, 450/10, 500/7, 600/3 & 700/2)

Commonly known as ‘SG’ or ductile cast iron; this material is often used where parts need to take a load or need to be impact resistant.  SG Iron is also a suitable alternative to Malleable Iron in many cases.

In addition, we can also offer ADI in grades 800/8, 1000/5, 1200/2, 1400/1



Carbon Steel A1, A2, A3, A4, A5, A6 – up to 5000kg

High Tensile Steel BT1, BT2 & BT3 – up to 2000kg

Stainless Steel 304 and 316 – up to 5000kg

Cast steel has many different properties such as wear resistance and high tensile strength.  Its applications are varied including where extreme temperatures and conditions are encountered.  Steel also lends itself to casting processes such as sand and lost wax.

304 and 316 are typical grades in the most common group of stainless steels; also known as austenitic stainless steels.  These grades exhibit characteristics of castability, weldability and corrosion resistance*

Important note about corrosion resistance of stainless steels:
Despite what the name implies, ‘stainless steel’ castings are ‘stain-less’ and not ‘stain-impossible’.  Under certain conditions, corrosion can happen in varying degrees. Careful selection of material grade and final surface finishes and treatments at design stage is important to achieve application requirements.
