Industry Focus: The Material Debate of Electrical Enclosures - Stainless Steel VS Cold Rolled Steel How to Choose More Scientifically?
With the acceleration of industrial intelligentization, the material selection of electrical enclosures and distribution boxes, as the core equipment of the power system has become a hot topic in the industry. Stainless steel and cold-rolled steel, as the two mainstream materials, which one is superior? This article will provide you with-depth analysis from the perspective of industry application.
1. Stainless Steel Electrical Enclosures: The "Guardian" in High Corrosive Environments
recent years, special scenarios such as chemical engineering and offshore engineering have increasingly stringent requirements for the corrosion resistance of electrical enclosures. Stainless steel materials (such as 30/316L) have become the first choice in these fields, thanks to their natural corrosion resistance. A well-known manufacturer of distribution boxes revealed: "In coastal area, the service life of stainless steel electrical enclosures is more than three times longer than that of ordinary materials."
Industry Case: A certain offshore wind power project 316L stainless steel electrical enclosures, successfully withstood salt mist corrosion, and maintenance costs were reduced by 40%. The explosion-proof distribution boxes a chemical plant were upgraded to stainless steel material, and the accident rate dropped by 60%.
2. Cold Rolled Steel Electrical Enclosures: The King of Performance Still Dominates
Despite the excellent performance of stainless steel, cold-rolled steel is still the preferred choice for ordinary industrial electrical enclosures due to its cost advantage Industry data shows that in 2023, the domestic distribution box market, cold-rolled steel material accounted for more than 70%. Experts pointed out: "The of spraying process has greatly improved the rust resistance of cold-rolled steel electrical enclosures, making the cost performance advantage more prominent."
Industry Dynamics: a smart transformation project of an automobile factory, 2000 cold-rolled steel electrical enclosures were treated with a special coating, achieving zero rust for 5 years.A well-known distribution box brand launched a new product of "Cold-rolled Steel Nano Coating", the price is only 1/3 of stainless steel and the order volume has increased dramatically.
3. Industry Recommendation: Key to Choose Materials by Scenario
In view of the material selection of electrical enclosures and boxes, the industry association released the latest guidelines: · Stainless steel priority: Chemical, coastal, food and medicine and other corrosive environments · Recommended-rolled steel: Dry indoor environment, cost-sensitive projects
4. Future Trend: Composite Material May Become the New Direction
It is reported that some leading have developed "Stainless Steel-Cold Rolled Steel Composite Electrical Enclosures", which takes into account both cost and performance. A leading distribution box enterprise predicts:The market share of composite materials will exceed 15% in 2025."
Conclusion: Whether it is stainless steel or cold-rolled steel electricalclosures, the key is to match the use scenario. The industry calls on users to choose rationally according to actual needs, avoiding "over-configuration" or "cutting corners"
