Compare all 6 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
As fabricated | Cheapest condition for non-critical, lightly loaded castings where dendritic structure and residual stress are tolerable. | 200 | 410 | 20 | 125 HB | 10 % IACS |
Stress relieved | Use when dimensional stability after heavy machining or weld repair matters but no grain refinement is required. | 200 | 405 | 23 | 118 HB | 10 % IACS |
Solution annealed | Softest and most machinable condition; pick it for heavily machined castings or where maximum ductility is wanted. | 200 | 400 | 27 | 112 HB | 10 % IACS |
NDefault Normalized | Standard supply condition: refines the as-cast structure and gives the specified 200 MPa yield with good toughness. | 220 | 430 | 25 | 125 HB | — |
Normalized and tempered | Choose when residual stresses from normalizing must be removed and slightly higher, more uniform toughness is required. | 225 | 425 | 26 | 122 HB | 10 % IACS |
Quenched and tempered | For thinner sections needing higher yield and toughness than normalized; hardenability of this low-C composition limits section size. | 300 | 500 | 23 | 155 HB | — |
What is GS200?
GS200 (1.0449) is a low-carbon cast steel carrying an older DIN-derived designation, available as-cast, stress-relieved, annealed, normalized, normalized-and-tempered or quenched-and-tempered. Default properties are 220 MPa yield, 430 MPa tensile, 25 % elongation and about 125 HB (70 HRB), with service up to 425 °C, so it suits lightly stressed sand-cast housings and general machinery parts where ductility and weldability matter more than strength. It has no useful natural corrosion resistance; GS240 or GE240 are the obvious steps up in strength. GS200 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,425°C (2,597 °F). GS200 has a yield strength of 220 MPa (31.9 ksi) and a tensile strength of 430 MPa (62.4 ksi) — weaker than 98% of steel grades. Elongation at break is 25% and the elastic modulus is 205 GPa (29.7 Msi).

Working with GS200
Is GS200 easy to machine?
Machines like mild steel but gummy — use positive-rake coated carbide, generous feed and coolant; skim sand skin and scale first to protect edges.
Can GS200 be welded?
Excellent weldability with E7018/ER70S-6; thin sections need no preheat, heavy sections 100–150 °C preheat and post-weld stress relief for repair welds.
Can GS200 be formed, bent or molded?
Green-sand or no-bake casting with ample risering and chills — the wide freezing range makes it prone to centreline shrinkage and hot tears at section changes.
GS200 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on GS200?
Shot-blast then prime/paint or zinc-coat; no useful natural corrosion resistance, and cast porosity limits mirror polishing and electroplating quality.

GS200 — frequently asked
What is GS200 used for?
GS200 is typically used for general machinery castings, housings and low-load brackets. In short: most ductile cast carbon grade; excellent weldability; lightly stressed castings.
What is the yield strength of GS200?
GS200 has a typical yield strength of 220 MPa (31.9 ksi) and a tensile strength of 430 MPa (62.4 ksi) — weaker than 98% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is GS200 easy to machine?
Reasonably — machinability is rated good (62/100, better than 89% of steel grades). Machines like mild steel but gummy — use positive-rake coated carbide, generous feed and coolant; skim sand skin and scale first to protect edges.
Can GS200 be welded?
Yes — weldability is rated excellent (88/100). Excellent weldability with E7018/ER70S-6; thin sections need no preheat, heavy sections 100–150 °C preheat and post-weld stress relief for repair welds.
What surface finishes work on GS200?
Shot-blast then prime/paint or zinc-coat; no useful natural corrosion resistance, and cast porosity limits mirror polishing and electroplating quality.
Can GS200 be formed, bent or molded?
Green-sand or no-bake casting with ample risering and chills — the wide freezing range makes it prone to centreline shrinkage and hot tears at section changes.
What is the maximum service temperature of GS200?
GS200 is rated for continuous use to about 425°C (797 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between GS200-N and GS200-QT?
N is the default condition — standard supply condition: refines the as-cast structure and gives the specified 200 MPa yield with good toughness. QT: for thinner sections needing higher yield and toughness than normalized; hardenability of this low-C composition limits section size. Yield strength is 220 MPa in N versus 300 MPa in QT.
