Working with GE360-F
Is GE360 easy to machine?
Machines like normalized 1045: carbide tooling, 120–180 m/min turning, watch for hard skin, scale and sand inclusions on the as-cast surface.
Can GE360 be welded?
Weldable with low-hydrogen electrodes or MAG but CEV ≈0.5–0.6 — preheat 150–250 °C, control interpass, and stress relieve at 600–650 °C after major repair welds.
Can GE360 be formed, bent or molded?
Sand or investment cast at ~1560–1600 °C with generous risering/chills; feed heavy sections to avoid shrinkage porosity and hot tears, allow ~2 % pattern shrink.
What surface finishes work on GE360?
No inherent corrosion resistance — shot blast then paint, zinc-rich primer, phosphate, or hot-dip galvanize; can be flame/induction hardened or hard chrome plated on wear faces.

GE360-F — frequently asked
What is GE360-F used for?
GE360-F is typically used for heavy-duty machine castings, mill housings and crusher parts. In short: strongest plain-carbon cast steel; cast equivalent of normalized 1045; lower ductility than Mn grades.
What is the yield strength of GE360-F?
GE360-F has a typical yield strength of 320 MPa (46.4 ksi) and a tensile strength of 620 MPa (89.9 ksi) — weaker than 81% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is GE360-F easy to machine?
Not especially — machinability is rated fair (42/100, worse than 73% of steel grades). Machines like normalized 1045: carbide tooling, 120–180 m/min turning, watch for hard skin, scale and sand inclusions on the as-cast surface.
Can GE360-F be welded?
With care — weldability is rated fair (45/100). Weldable with low-hydrogen electrodes or MAG but CEV ≈0.5–0.6 — preheat 150–250 °C, control interpass, and stress relieve at 600–650 °C after major repair welds.
What surface finishes work on GE360-F?
No inherent corrosion resistance — shot blast then paint, zinc-rich primer, phosphate, or hot-dip galvanize; can be flame/induction hardened or hard chrome plated on wear faces.
Can GE360-F be formed, bent or molded?
Sand or investment cast at ~1560–1600 °C with generous risering/chills; feed heavy sections to avoid shrinkage porosity and hot tears, allow ~2 % pattern shrink.
What is the maximum service temperature of GE360-F?
GE360-F is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between GE360 +N and GE360-F?
+N is the default condition — standard supply condition: refines the as-cast structure and meets the GE360 strength/elongation minima at lowest heat-treat cost. F: lowest-cost condition for non-critical, lightly loaded parts where the specified mechanical minima are not certified. Yield strength is 400 MPa in +N versus 320 MPa in F.
