304 and 316 are common materials of stainless steel wire ropes. Although they are both austenitic stainless steels, there are obvious differences in composition, performance and application.
The following are specific comparisons:
| Comparison Project | 304 Stainless Steel Wire Rope | 316 Stainless Steel Wire Rope |
| Chemical composition | 18% Cr, 8% Ni | On the basis of 304, about 2% molybdenum and a little nitrogen are added. |
| Corrosion resistance | Good atmospheric corrosion resistance, not resistant to chloride-containing environment (such as seawater and salt fog), and prone to pitting corrosion. | Molybdenum element significantly enhances its chloride ion corrosion resistance, and is suitable for strong corrosion scenes such as ocean and chemical industry. |
| High temperature resistance | It can be used stably below 800℃ | The maximum service temperature is 1200-1300℃, which is more suitable for high temperature environment. |
| Mechanical character | Moderate strength and hardness | Adding nitrogen element, the strength and hardness are slightly higher, and it can withstand large tensile force. |
| Application scenario | General corrosion-resistant demand scenarios such as interior decoration, furniture slings, and common building protective nets | High corrosion resistance and high temperature resistance fields such as marine engineering, food and chemical industry, medical equipment and nuclear industry. |
| Price | Low cost and affordable market price. | Because rare elements such as molybdenum are added, the price is 10%-20% higher than that of 304. |
