Samestelling en eienskappe van 321 vlekvrye staal

When we talk about stainless steel, 321 vlekvrye staal is one of the most eye-catching varieties. This material is favored by various industries because of its unique chemical composition and excellent performance. Today, let’s uncover the mystery of 321 stainless steel together, learn more about the samestelling en eienskappe van 321 vlekvrye staal, and see why it stands out among many stainless steel.

Wat is die chemiese samestelling van 321 vlekvrye staal?

The main chemical components of 321 stainless steel include:

1. Iron (Fe): About 60-75% of the total mass of the alloy.
2. Nickel (Ni): Approximately 8-11%. Improves the corrosion resistance of the alloy.
3. Chromium (Cr): Approximately 17-20%. Increases the hardness, wear resistance, and corrosion resistance of the alloy.
4. Manganese (Mn): about 2%. Improves the strength and toughness of the alloy.
5. Silicon (Si): about 1%. It has an impact on the cold workability of the alloy.
6. Carbon (C): limited to less than 0.08%. The hardness and strength of the alloy are controlled.
7. Phosphorus (P) and sulfur (S): Both are limited to low levels to avoid negative effects on the corrosion and mechanical properties of the alloy.

These chemical components work together to let 321 stainless steel have good corrosion resistance, heat resistance, mechanical strength, and good welding performance.
