Cast Steel Price Calculator User Manual

This User Guide will teach you how to use our cast steel casting price calculator.

1. Material Grade

Most of alloy cast steel will have the alloy Chrome (Cr), Molybdenum (Mo), Nickel (Ni) and

Copper (Cu). These alloy compositions will affect their casting prices directly, so you must input

their composition (percentage) into our calculator.

You could search Google to get the chemical composition for your alloy, for example, as for

stainless steel 316, you could see its chemical composition is Ni 10.00-14.00, Cr 16.00-18.00, Mo

2.00-3.00. So, you could input our calculator by Ni as 14.00, Cr as 18.00, Mo 3.00.

As for the carbon steel, such as mild steel, medium-carbon steel and high-carbon steel, they do not

have certain alloy composition, so you do not need to input any alloy composition, just leave this

area as blank.

2. Casting Weight

If you want to get the unit price USD/pcs, then you have to input the unit weight. You may get the

unit weight from drawings, after input the unit weight, you need to tell our calculator what unit

weight it is. You could choose "Raw casting weight" or "Finish weight".

"Raw casting weight" means the weight for castings before machining, or do not need any

machining.

"Finish weight" means the weight for machined casting parts, or the castings after machining

process. So, if the castings need further machining works, then the "Finish weight" will be lighter

than "Raw casting weight".

Normally, if you get the unit weight from casting drawing, then it should be raw casting weight,

but if you get the weight from machining drawing, then it should be the "Finish weight".

If you are not sure about what unit weight you get, then, as our Dandong Hengrui Foundry's experience, most of them are "Finish weight".

Be careful, this choice will affect the unit weight about 10% or 20%, so you must choose it

carefully.

3. Complexity of Castings

DANDONG IRON CASTING GROUP

The complexity of the castings will affect their prices. The complex castings will need more

materials to make sand cores, and also more works for sand cores making and assembly. Also will

cause higher defective rates. All these will affect their prices.

Please choose one as your judgment to the complexity of your casting parts.

"Very Simple" means your casting parts are very simple. Simple shape, no complex inside

structures, such as simple plate, rings, balls. Most of counter weights could be taken as very

simple.

"Normal" means the casting parts only have one hole or simple inside structure.

"Complex" means the casting parts have complex inside or outside designs, many characters. Not

very easy to make.

"Very Complexity" means the casting parts are very complex, choose this carefully, because it will

affect the casting prices seriously.

If you are not sure about its complexity, you are better to choose "Normal" or "Complex".

4. Selection of Casting Process

As for the steel castings, there are several different casting processes, or called as casting

production methods. The casting processes will affect the casting prices very seriously, choosing

the suitable casting process will be very important.

If you do not have high requirements to the surface quality and dimensional tolerance, then you

could choose the sand casting process, which is the cheapest one. Plus, if your casting part is over

100 kg per piece, then you will have to choose the sand casting process.

If you have certain requirements to the surface quality and dimensional tolerance, you could

choose the lost wax investment casting process by water glass material. This casting process is

much better than sand casting process, but its price is not low and it can not be used to produce

steel castings over 100 kg normally.

If you have very high requirements to the surface quality and very high dimensional tolerance,

then you could choose the lost wax investment casting process by silica sol material. This casting

process could produce perfect steel castings, however, it can not be used to produce large castings

over 50 kg, and its prices are extremely high. Do not choose it as long as you are sure you need it.

For the difference of these casting processes, you could refer to our article Sand Casting vs. Water

Glass Investment Casting vs. Silica Sol Precision Casting

5. Machining Description

Dandong Iron Casting Foundry's casting price calculator could help you to get the machining costs.

Of course,the accurate machining cost is very difficult to get unless you are very professional machining engineer, so our calculator is just help you to get the approximate costs.

If you just need raw castings, or the castings do not need further machining, then you should

choose "No Machining".

You could check how many positions or surfaces will need machining, if there are many

machining positions and surfaces, then you could take it as complex or very complex.

If your casting parts need CNC centers, or very high accurate machining, then you may choose

complex or very complex.

If you think there are not many machining positions, or the tolerance is not very high, then you

could choose the "Normal Machining".

But please notice that the different machining complexity will affect the machining costs very

seriously, so please choose it carefully.

6. Surface Painting and Coating

If you want foundry to paint them or do some certain surface coatings, then you could choose the

painting method accordingly.

7. Packing and Delivery to Local Seaport

Packing cost means our Dandong Foundry will pack them into fumigation-free plywood crates.

We will also deliver them to our local Dalian port, then they will be ready for shipment. This is

FOB China terms.

If you want us to pack them and deliver them to the local seaport, then you could choose the

options accordingly.

Now, please click the button "Price Calculation", then you will see the prices for the casting price,

machining price, paint & coating price, packing & delivery cost, and total price.

By the way, the Price Index FG, and RG are only used by us to adjust the prices according to the

current material and manpower costs. The exchange rate will be adjusted by us too. So, the users

do not need to care about these data.
