On this page, we would focus on greycast iron. First, let’s know a few essential information about grey iron.

What’s Grey Cast Iron?

Grey or gray iron has a graphitecomponent that gives its color and name. Grey iron is classified according to its tensile strength.

Here’s an example:

Grey iron under Class 20 has low orlittle tensile strength but higher in ductility. In Classes 3O, 40 (including)60, the grey iron has great strength. (But take note: the high strength of theiron reduces its ductility.) Meanwhile, the Class 😯 grey iron has increasedtensile strength, but it’s brittle.

Remember: Graphite is added or is withinmolten metal during iron casting.

Grey iron is 95% Iron in weight, 4%carbon, and 3% silicon.  You can findhigh silicone amount in grey cast iron that’s responsible for graphiteproduction when the alloy is heated. Take note: the deflectionof the graphic microstructure gives iron its grey color.

Also, it’s also noteworthy to mention:the production of ductile cast iron slows down the formation or growth ofgraphite. The process also allows carbon to separate as a spheroidal graphiteparticle.

Caster Metal monitors thetemperature and timing in melting grey cast iron as it plays an important rolein the iron castings.

How We Mold Grey Cast Iron?

After we achieve the right melttemperature, we pour the metals into molds. (The molds we’re using could beone-piece or two-piece split molds.) The two-piece mold has a cope and dragthat meet to the parting line.

Take note: the molds could be taper or draftmade to the edges. (In this way, the cast part is removed easily.)

During the process, core results toavoid in the grey cast iron and the core is destroyed in the process.  Hence, the core becomes a disposablematerial.

What happens after the mold breaksout?

The grey cast iron needs heattreatment so that It has strength.  Theheating or cooling is a secondary process that gives tempering, case hardening,annealing or quenching of the cast iron. The grey iron is sealed through metal impregnation that utilizeseffective vacuum pressure that seals the surface.

Then, our experts use shot peening (atype of sandblasting) to hammer a metal’s outer layer to create a solid finish.Thus, the metal gains additional strength that resists cracking and other metalproblems.

Why Choose Our Grey Iron Casting?
