What is GE240?
GE240 (1.0446) is a medium-strength general engineering cast carbon steel, supplied as-cast (F) or in the annealed, normalized and quenched-and-tempered conditions. In the default condition it delivers 265 MPa yield, 480 MPa tensile and 24 % elongation at about 145 HB, with a weldability score of 85, which makes it a routine choice for sand and investment castings such as machine bases and pump bodies. It offers higher tensile strength than GE200 but has no inherent corrosion resistance and a 400 °C maximum service temperature; GE270 is the next step up when more strength is needed. GE240 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,470°C (2,678 °F). GE240 has a yield strength of 265 MPa (38.4 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 92% of steel grades. Elongation at break is 24% and the elastic modulus is 210 GPa (30.5 Msi).

Working with GE240
Is GE240 easy to machine?
Machines like normalized 1020–1025 steel (~65 % of AISI 1212); use rigid setups and carbide tooling, and expect abrasive cast skin — take a deep first cut through the scale.
Can GE240 be welded?
Readily weldable by SMAW/GMAW/SAW with low-hydrogen consumables (E7018 class); preheat 100–150 °C for sections over ~30 mm and stress-relieve at 580–620 °C after major repair welds.
Can GE240 be formed, bent or molded?
Sand or investment cast with generous feeders and chills — steel shrinks ~2 % and needs strong risering; normalize after casting for uniform properties.

What surface finishes work on GE240?
No inherent corrosion resistance: shot-blast then prime/paint, zinc-spray, hot-dip galvanize or phosphate; can be flame or induction surface hardened only marginally due to low carbon.

GE240 — frequently asked
What is GE240 used for?
GE240 is typically used for machine bases, gear housings, pump bodies and general engineering castings. In short: medium-strength cast steel; highly weldable casting grade; stronger than GE200.
What is the yield strength of GE240?
GE240 has a typical yield strength of 265 MPa (38.4 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 92% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is GE240 easy to machine?
Reasonably — machinability is rated good (62/100, better than 89% of steel grades). Machines like normalized 1020–1025 steel (~65 % of AISI 1212); use rigid setups and carbide tooling, and expect abrasive cast skin — take a deep first cut through the scale.
Can GE240 be welded?
Yes — weldability is rated excellent (85/100). Readily weldable by SMAW/GMAW/SAW with low-hydrogen consumables (E7018 class); preheat 100–150 °C for sections over ~30 mm and stress-relieve at 580–620 °C after major repair welds.

Sand or investment cast with generous feeders and chills — steel shrinks ~2 % and needs strong risering; normalize after casting for uniform properties.
What is the maximum service temperature of GE240?
GE240 is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between GE240 +N and GE240-F?
+N is the default condition — standard supply condition: normalizing refines the as-cast dendritic structure and gives the specified 240 MPa yield with good toughness. F: economy option for low-stress, non-impact parts where only stress relief is applied; properties are less uniform than +N. Yield strength is 265 MPa in +N versus 245 MPa in F.
