Alloy steel investment castings
Alloy steel is a steel adding other elements in addition to iron,carbon.So Fly foundry is a chinese leading manufacturer for alloy steel investment castings.It can obtain special properties like high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistant, no special performance.The main elements of alloy steel are silicon,manganese,chromium,nickel, molybdenum,tungsten,vanadium,titanium,niobium,zirconium,cobalt,aluminum,copper,boron,rare earth,etc.So Fly investment casting foundry usually use this material to manufacture alloy steel investment casting with lost wax casting technology for our customers.The common materials Fly investment casting foundry made for customers are 42CrMo,20Mn,8630,8620,4140,4130,35CrMo,20Mn5,40CrNiMo.We could use these material to custom alloy steel investment castings for different industries.
Chemical composition for common alloy steel investment castings:
| C | Si | Mn | Cr | Mo | P≤ | S≤ | Ni | |
| 42CrMo | 0.38-0.45 | 0.17-0.37 | 0.50-0.80 | 0.90-1.20 | 0.15-0.25 | |||
| 35CrMo | 0.32-0.40 | 0.17-0.37 | 0.40-0.70 | 0.80-1.10 | 0.15-0.25 | |||
| 40CrNiMo | 0.37-0.44 | 0.17-0.37 | 0.50-0.80 | 0.60-0.90 | 0.15-0.25 | 1.25-1.65 | ||
| 4130 | 0.28-0.33 | 0.15-0.35 | 0.40-0.60 | 0.80-1.10 | 0.15-0.25 | 0.035 | 0.04 | |
| 4140 | 0.38-0.43 | 0.15-0.35 | 0.75-0.10 | 0.80-1.10 | 0.15-0.25 | 0.035 | 0.04 | |
| 8630 | 0.28-0.33 | 0.15-0.35 | 0.70-0.90 | 0.40-0.60 | 0.15-0.25 | 0.035 | 0.04 | 0.40-0.70 |
According to the total number of alloying elements,alloy steel investment casting can be divided into two major categories of low-alloy steel castingand high-alloy steel casting.
1,low alloy steel investment casting, the main application of manganese,silicon manganese and chromium,etc.Like ZG40Mn, ZG30MnSi1, ZG30Cr1MnSi1 so on.Used to make gears,hydraulic cylinder and turbine rotors and other parts.However,ZG40Cr1 is often used to manufacture high-strength gears,high-strength shafts, and other important force parts.
2,high-alloy steel investment casting, with wear-resistant, heat-resistant or corrosion resistance and other special properties. Such as high-manganese steel ZGMn13,is an anti-wear steel,mainly used in the manufacture of friction in the dry operating conditions used parts, such as excavator grab and grab teeth,crawler tractors and tanks,etc.chrome-nickel stainless steel ZG1Cr18Ni9 and chrome stainless steel ZG1Cr13 and ZGCr28 ect, has high corrosion resistance to nitric acid,mainly for the manufacture of chemical, petroleum,chemical and food equipment parts.
Comparing with carbon steel investment castings,the properties of alloy steel investment castings are better than carbon steel investment castings and its application is becoming more wide.But the price is higher.Because of the advantages of alloy steel investment castings,we often use them to manufacture excavator bucket teeth,agricultural castings for tillage points,ect.So pls do not hesitate to contact us or email ella.fly02@cnool.net directly when you need,we will revert to you asap.
