Water Pump Impeller Parts Graphite Cast Iron GGG-40 Material ASTM A536

Water Pump Impeller Parts Graphite Cast Iron GGG-40 Material ASTM A536

Product Description and Process

1.Water Pump Impeller Parts Ductile iron Castings GGG-40 Material Sand Casting Foundry

2. Production process: green sand molding, pre-coated sand molding and resin sand molding which can produce iron castings from 50 gram to 2000 kilograms

3. Machining process: CNC machine, machining center, lathe, mill machine, drill machine, etc.

4. Surface treatment process: paint coating, electrophoretic coating, electrogalvanizing coating, black oxide coating, phosphate coating, powder coating, etc.

Product Material and Uses
1. Normally produce with gray iron HT200, HT250, ductile iron 65-45-12, 60-40-18, 80-55-06, 80-60-03, etc.
2. The ductile iron casting products are widely used for Auto-cars, trains, trucks, vehicle components, mining machinery components, agricultural machinery parts, textile machinery parts, construction machinery parts, valves and pump parts, etc.

What is Ductile Iron Used For? (Applications)

Ductile iron is great for use where you need strong metal with wear resistance.
Here is a sample list of things made from or contain ductile iron:
Pipe and pipe fittings (almost 50% of ductile iron sold in the US is for pipe and fittings)
Connecting rods (like in engines)
Disc brake calipers
Gears and Gear Boxes
Housings and manifolds
Hydrostatic Barrels
Idler arms
Large Machines
Machine Tooling
Military uses
Piano Harps (the part that holds the strings of a piano)
Spindle supports
Steering knuckles
Suspension system parts
Truck axles
Valves (especially high-pressure valves)
Wheel hubs
Yokes for power transmission

What is the difference between Ductile Iron and Cast Iron?
Cast iron refers to all iron parts that are cast and have a high carbon content, but in normal usage, “cast iron” refers to gray iron, the cast parts with weaker iron structures containing graphite flakes. Ductile iron must specifically have the spherical graphite structure in the metal.
Regular cast iron can be cast cheaply, machined very easily, and strength can be added through heat treating. Gray iron lacks the strength and durability of ductile cast iron. Ductile iron castings are not much more expensive than gray iron castings yet if there is no need for the benefits of ductile iron you should probably stick with the gray iron castings.

What is in Ductile Iron? (Composition)

If you were to do a chemical analysis of ductile iron, this is what you would normally find:
Iron ~94%
Carbon 3.2 – 3.60%
Silicon 2.2 – 2.8%
Manganese 0.1 – 0.2%
Magnesium 0.03 – 0.04%
Phosphorus 0.005 – 0.04%
Sulfur 0.005 – 0.02%
Copper <= 0.40%
To improve the strength of ductile iron, additional tin or copper can be added. To improve corrosion resistance, copper, nickel, or chromium can replace anywhere from 15-30% of the iron.
