The core components of steel Forging cost
The cost of steel castings is not a single number; it is composed of multiple factors. The market price of steel castings per kilogram typically ranges from 20 to 70 yuan, depending on the following key factors:
1. Raw material cost: Ordinary carbon steel costs approximately 9 to 10 yuan per kilogram, while alloy steel (such as chromium-molybdenum steel) costs as much as 15 to 30 yuan per kilogram. Costs are expected to fluctuate significantly in 2023 due to fluctuations in iron ore prices.
2. Process complexity: Simple sand casting costs approximately 8 to 9 yuan per kilogram, while precision casting (such as the lost wax method) can reach over 50 yuan per kilogram.
3. Labor and energy consumption: Labor costs for small and medium-sized enterprises are approximately 9 to 10 yuan per kilogram, while automated factories can reduce this to 6 to 7 yuan per kilogram.
The Deeper Reasons for Price Differences
Quotations for the same type of steel casting can vary several times. Reasons include:
Batch Effect: The cost of small-batch production of a single piece (such as custom parts) can be 2-3 times that of a full batch.
Post-processing Requirements: If heat treatment or flaw detection is required, an additional 5-15 yuan per kilogram will be added.
How to Reduce Procurement Costs?
1. Design Optimization: Reducing wall thickness or simplifying the structure can reduce material usage.
2. Selecting Alternative Materials: Using Q235B instead of alloy steel in non-critical areas can reduce costs by 30%-40%.
3. Negotiating Prices Through Long-Term Partnerships: Signing an annual agreement with a foundry typically offers a 5%-10% discount.
