The difference between stainless steel precision casting process and traditional steel casting process

Edit:Xiangyang Liqiang Machinery Co., Ltd.UpDate:2019-12-16

Stainless steel casting is a kind of less drilling and an excellent production process in the foundry industry. Its application is very common. It is not only suitable for forging of various types and various aluminum alloys. So when everyone is using stainless steel casting, generally everyone understands the difference between the processing technology of stainless steel casting and the processing technology of steel castings?
1. Tapping temperature: stainless steel plate is higher than carbon steel;
2. Liquidity of molten steel: stainless steel plate is worse than carbon steel;
3. Condensation method: stainless steel plate is viscous coagulation, carbon steel is sequential coagulation;
4. Molten steel reducibility: stainless steel plate is more susceptible to air oxidation than carbon steel.
Stainless steel precision casting products can be divided into two categories: military, airline products and cargo products. The former one has high quality regulations, and the latter one is not as good as the former one. Nowadays, precision castings are basically used in aviation, aerospace, and military industries, but are basically used in all industrial sectors, such as electronic devices, crude oil, chemical plants, electric power, road transportation, light industry, textiles, pharmaceuticals, medical machinery, etc.
When aluminum die-casting, metal material must be used. It is a permanent forging process, which is different from precision castings. Because castings are mostly forged with aluminum alloy profiles or magnesium alloys and alloy copper metal materials with lower melting points. Precision castings belong to one-time metal mold castings. The key is stainless steel plates, titanium metal, heat-resistant alloys, cast steel valves and other high-line melting point metal composite materials. It is not easy to have sand holes during aluminum die-casting. If stainless steel precision castings are handled properly, sand holes are not easy to appear. Refining is a kind of name for gravity casting of aluminum alloy. It is actually a forging process carried out under force. Forging processes other than working pressure forging must use the aluminum gravity casting method.
At the forming level, stainless steel precision castings can endanger the quality of castings in most and every stage. Therefore, if you want to improve the quality of castings, you must strictly supervise the important links and the actual operation staff must be highly qualified. Only by mastering all the important links can the quality of castings stabilize and produce qualified products. Secondly, the quality of castings is also closely related to the raw materials used. If the quality of the raw materials is high, the quality of the manufactured castings will be high, and the opposite is the same. Therefore, when purchasing, you must ask clearly what kind of stainless steel plate the casting is made of. For example, products made of 304 stainless steel plate are very prone to rust and mildew when placed in a relatively humid and cold area.
