Huawei Investment Casting  is one of the largest lost wax foundries in China. Through our decades of experience with investment casting, we can assure efficiently produced high quality castings. .


Huawei Investment Casting has the possibility to compose her own alloy elements, so nearly any type of steel can be created and casted in house. Below you will find a short overview of the steel types that are regularly cast at CIREX.

DIN Material Similar to Strength (N/mm2) Elongation (%) Hardness
1.2346 GX 38CrMoV5-1 - > 1300 - 50-58 HRc
1.2436 X 210CrW12 - - - 45-55 HRc

1.7225 GS 42CrMo4 - 650-800 > 12 90-100 HRb

In addition to the above mentioned “standard’ steel alloys, Huawei Casting  can also cast high quality and special steels. These types of steel are characterised by high tensile strengths, high elongations, high hardness or corrosion resistance. That is why these alloys are especially suitable for operating in environments which are aggressive (hostile) or subject to large differences in temperature. Below you will find a short overview of these types of steel:

DIN Name Similar to Strength (N/mm2) Elongation (%) Hardness
1.4549 GX 4CrNiCuNb16-4 17-4PH > 1000 > 6 > 30 HRc
2.4964 GX 275CoCrW 55-30-12 Stellite > 750 - 37-43 HRc
2.4603 NiCr30FeMo Hastelloy - > 8 -
2.4856 NiCr22Mo9Nb Inconel 625 - - -
- GJS-X SiMo 5-1 SiMo > 550 > 5 -
- Ni-Resist D-5S   - - -
1.3912 Invar 36 Invar - - -


Huawei Investment Casting develops and produces high quality investment castings which can be cast in virtually any steel alloy. Steel is an alloy consisting of iron (Fe) and carbon (C), where the term ‘steel’ is used for iron alloys with a limited amount of carbon (less than 1,9%). When the iron contains more than 2% carbon, we talk about ‘cast iron’ instead of steel.

Next to the basic elements of iron (Fe) and carbon (C), steel often contains multiple alloy elements such as: chromium, nickel, manganese, silicon or molybdenum. Depending on the different alloy elements and the quantity of these elements (%) within the steel, a unique steel alloy can be created. By varying with different alloy elements and quantities, almost any steel alloy can be created and cast.

Steel can be divided into three different groups based on the amount of added alloy elements:

  • Unalloyed steel                   (maximum 1,5% alloy elements)
  • Low-alloyed steel                (from 1,5% to 5% alloy elements)
  • High-alloyed steel               (more than 5% alloy elements)

Stainless steel (INOX) is one of the steel types that Huawei Investment Casting is specialised in. Stainless steel is cast in large quantities. This steel type is known for its corrosion resistance after contact with aggressive  substances and water. Next to the elements iron(Fe) and carbon (C), stainless steel also contains chromium (Cr) and nickel (Ni). For more information about stainless steel investment casting, click here!


A proper design starts with the right choice of material and knowledge of steel. The metallurgists of Huawei Investment Casting will be glad to assist you in choosing the most appropriate alloy for your application. Depending on the application, the necessary hardness, tensile strength or elongation of the steel, an alloy will be determined and the most appropriate steel will then be chosen. Our metallurgists have extensive practical knowledge of steel alloys, heat & surface treatments and casting structures. Do you have any specific questions? Then feel free to contact CIREX.
