Stainless steel castings are steel castings used in various stainless steel materials, mainly used in various media corrosion conditions. Too high carbon content of stainless steel castings will generally cause alloy steel castings to become bad products and cause some waste of resources. Many people do not understand this reason, and we need to avoid it. So what is the reason for the high carbon content of stainless steel castings?

1. Unreasonable setting of pouring conditions for alloy steel castings: If the pouring filling process is set too long, the temperature of the molten steel during the pouring process is low, especially for the position where the wall thickness of the casting increases, the solidification speed of the molten steel is slow. Increase the amount of carburization and carbon deposition of steel castings.

2. The carbon content in the smelting ingredients for the production of alloy steel castings is not strictly controlled, especially the carbon content in various scrap steels and whether there are materials with other alloy components in various scrap steels.

3. Unreasonable setting of the pouring system for alloy steel castings: especially the unreasonable configuration of the vacuum system and the pouring flask or the casting process modeling, which causes the castings to be poured in the process, so that the thermal decomposition products of the pattern cannot be quickly and quickly discharged from the pouring The cavity causes carburization or carbon deposition of the casting.
