Estimation of Steel Casting Prices Per Pound, KG and Ton

In this article we try to introduce some information about the estimated costs of cast steel castings by weight. Actually both the costs of cast iron castings and cast steel castings have the similar factors which can decide how much we cost, such as complexity of casting structure, casting size, materials and the demand quantities per month or year.

Generally speaking the cast steel castings always cost higher than iron castings. This is caused mainly by two factors. The cast steel materials is more expensive, especially the steel alloys and the stainless steel. If the customers require special mechanical properties like wear-resistance, heat-resistance or anti-rust performance, the special chemicals (such as Mn, Mo, Cr, Ni) should be added into the molten metal during casting. Of course, the heat treatment tempering, quenching, annealing, carburization or normalization are usually made for steel castings to get the desired mechanical properties.

The other factor why steel casting is more expensive is the casting process. Comparing to the gray cast iron and ductile cast iron, which is cast mainly by green sand casting or shell molding casting, the steel castings should always be produced by so-called speical casting process, including investment casting (lost wax process), lost foam casting, vacuum casting or other new technologies. These above casting processes could make sure the accurate dimensions, well surfaces and good mechanical properties. Accordingly, the costs would also be higher of course.

	Investment Casting	High	0.0 - 0.5 lb (0.1 - 1.0 kg)	3.53	7.80	7800
			0.5 - 22.0 lb (1.0 - 50.0 kg)	3.44	7.60	7600
		Normal and Medium	0.5 – 4.5 lb (1.0-10.0 kg)	3.26	7.20	7200
			4.5 - 450 lb (10.0-1000 kg)	3.12	6.90	6900
Stainless Steel (take AISI 316 for example)	Sand Casting	High	0.0 - 0.5 lb (0.1 - 1.0 kg)	2.12	4.68	4680
			0.5 - 22.0 lb (1.0 - 50.0 kg)	2.04	4.52	4520
		Normal and Medium	0.5 – 4.5 lb (1.0-10.0 kg)	2.03	4.48	4480
			4.5 - 450 lb (10.0-1000 kg)	2.00	4.42	4420
	Investment Casting	High	0.0 - 0.5 lb (0.1 - 1.0 kg)	4.59	10.15	10150
			0.5 - 22.0 lb (1.0 - 50.0 kg)	4.44	9.82	9820
		Normal and Medium	0.5 – 4.5 lb (1.0-10.0 kg)	4.32	9.56	9560
			4.5 - 450 lb (10.0-1000 kg)	4.17	9.21	9210
Note: The above estimation is just based on the EXW price terms, steady costs of iron & steel, and the exchange rates. Any change of these factors will influent the casting costs.
