Alloy Nickel200 steel plate (UNS N02200) achieves its precise chemical composition through a systematic production process that combines high-purity raw materials, advanced smelting/refining techniques, and strict quality control. Here's a detailed breakdown of how its 化学成分 (chemical composition) is formed:

1. Raw Material Selection

Nickel200 starts with high-purity nickel ores (e.g., pentlandite or laterite) or recycled nickel scrap. Key requirements include:

 

Nickel Content: ≥99.0% (minimal impurities like sulfur, phosphorus, and iron).

Trace Elements: Careful selection to limit carbon (<0.15%) and other alloying elements (e.g., iron ≤0.4%, copper ≤0.25%) 12.

Purity Standards: Compliance with ASTM B162 and ISO 6208 ensures raw materials meet specifications 16.

2. Smelting Process

a. Melting

Electric Arc Furnace (EAF):

High-purity nickel is melted at 1500–1600°C under an inert gas atmosphere (e.g., argon) to prevent oxidation 13.

Scrap nickel is sorted and preprocessed to minimize contamination (e.g., removing non-nickel metals)
