3. Manufacturing Techniques for Nitro V Stainless Steel

Nitro V’s manufacturing requires precision to preserve nitrogen content and alloy balance—critical for its performance:

3.1 Primary Production

• Electric arc furnace (Eaf): Scrap stainless steel is melted, and high-purity alloys (хром, молибден) добавлены. Nitrogen is injected under pressure to ensure solubility—key to Nitro V’s strength.
• Basic oxygen furnace (Боф): Редко используется (EAF is better for nitrogen control); used only for high-volume, lower-precision parts like architectural railings.
• Вакуумная дуга переворачивает (НАШ): For medical/ aerospace grades—molten steel is remelted in a vacuum to remove impurities (НАПРИМЕР., кислород, сера), ensuring biocompatibility and uniformity.

3.2 Secondary Processing

• Горячая катящика: Нагретый до 1100 - 1200 ° C., rolled into plates, батончики, или простыни (for chemical tanks or architectural parts). Hot rolling enhances grain flow and retains nitrogen content.
