ASTM 4340 Alloy Steel Precision Cast Steel Parts Water Glass Investment Castings

 

 

Product Description and Process

ASTM 4340 Alloy Steel Precision Casting Lost Wax Water Glass Investment Castings Foundry

 

Production process: green sand molding, pre-coated sand molding, lost wax investment casting process

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

 

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

 

Product Material and Uses

Normally produce with ASTM A148/148M, ZG40Mn, ZG40Cr, ZG20SiMn, ZG35SiMn, ZG35CrMo, ZG35CrMnSi, etc.

 

The alloy steel casting products are widely used for Auto-cars, trains, trucks, vehicle components, mining machinery components, agricultural machinery parts, textile machinery parts, construction machinery parts, etc.

 

Low and High Alloy Steels

 

Low Alloy Steels add alloying elements such as nickel (Ni), chromium (Cr), and molybdenum (Mo) to attain specific properties. Depending on the alloying elements used, there can be great variation between different low alloy steels.

The total alloy content can range from 2.07% to approximately 10.5%. For many low-alloy steels, the primary function of the alloying elements is to increase hardenability (the degree to which the steel will harden during heat treatment). Alloy additions can also be used to reduce environmental degradations under certain specified service conditions.

 

High Alloy Steels are usually a type of stainless steel, the most widely consumed commercial high alloy steel. Stainless steels contain at least 10.5% chromium, along with other alloys such as nickel to alter other properties (such as strength or weldability) in addition to corrosion resistance.

 

Lost Wax Investment Casting Process

In lost wax investment casting, a sacrificial detailed wax pattern of the desired finished part is created and mounted onto a wax "tree", which includes the metal delivery system (gates and risers). The tree is alternately dipped into a ceramic slurry and sprinkled with stucco material, and is allowed to dry. This process is repeated until a thick shell is created over the wax pattern. The wax pattern is melted out leaving a cavity in the shape of the pattern. The cavity is filled with molten metal. After solidification, the shell is broken away, the gating material removed, and the finished part remains.

Advantages of Investment Casting

 

How are Investment Castings Made?

Developing investment castings involves creating an original wax model, coating the image with plaster and building of successive layers until a strong shell envelopes the model. After melting out the wax, molten metal will be poured into the mold, creating a perfect duplicate of the original wax pattern. Compared to machining apart, investment casting can economically offer undercuts, high definition, complex detail and a smooth surface finish.

Most often, investment casting is the only way a part can be economically manufactured.
