1. Raw material cost share
Base cost weight: stainless steel valve production, raw material costs account for 40% -60% of the total cost, of which nickel, chromium and other alloying elements price fluctuations directly affect the overall cost. 316 stainless steel, for example, nickel content of 10% -14%, nickel prices rise by 10%, the cost of stainless steel increased by 3% -5%, corresponding to the cost of the valve rose 2% -3%.
Special scenarios amplification effect: in the field of high-end valves (such as nuclear power, deep sea engineering), super duplex steel (UNS S32707) and other special stainless steel accounted for a higher proportion of raw material price fluctuations on the total cost of the impact of up to 15%-20%. The impact of raw material price fluctuations on the total cost can be up to 15%-20%.
2. Price fluctuations in the transmission mechanism
Direct conduction: stainless steel prices rose 10% each, ordinary stainless steel valves (such as DN100 gate valve) production costs increased by 5% -8%, if the enterprise can not fully pass on the cost, the gross profit margin will be compressed by 3-5 percentage points .
Indirect transmission:
Sealing materials (such as PTFE) and stainless steel to form a supporting supply chain, stainless steel prices may be pushed up the cost of seals along with 2% -4%.
International nickel policy (such as Indonesia's export restrictions) led to 2025 stainless steel prices rose 12% year-on-year, corresponding to the electric stainless steel valve manufacturing cost increase of 8%-10%.
3. Typical scenario case study
| Type | Raw material sensitivity | Impact of price volatility |
|---|---|---|
| Common stainless steel ball valve | middle | 316 stainless steel costs 55%, nickel price up 10% → unit price up 5% |
| Nuclear Main Steam Valve | high | Super duplex steel accounted for 70 per cent of the cost, with raw material fluctuations leading to a 15 per cent change in cost |
| Pneumatic Fluorine Lined Butterfly Valve |
higher | Stainless steel accounts for 50 per cent of manufacturing costs and 80 per cent of price fluctuations are transmitted efficiently |
