Frequently Asked Questions (FAQs)

What are the key certifications to look for when evaluating the quality of electrical steel from Chinese suppliers?

When assessing the quality of electrical steel from Chinese suppliers, look for certifications such as ISO 9001 and ISO 14001. These certifications indicate that the manufacturer adheres to international standards for quality management and environmental management. Additionally, inquire about their production process and quality control measures to ensure the products meet industry standards.

How dominant is China in the global electrical steel market?

China is highly dominant in the global electrical steel market. In 2023, China produced 15.28 million tonnes of electrical steel, accounting for a significant portion of global production. Chinese manufacturers such as Baosteel, WISCO, Ansteel, and Shagang lead the global market in both grain-oriented and non-oriented electrical steel, with China producing 56% of global grain-oriented electrical steel and 72% of global non-oriented electrical steel.

What are the different types of electrical steel commonly produced in China?

Chinese manufacturers produce two main types of electrical steel: grain-oriented and non-oriented electrical steel. Grain-oriented electrical steel is primarily used in transformers due to its high magnetic permeability, while non-oriented electrical steel is used in motors and other electrical devices. Both types are crucial for various applications, including power generation, transmission, and consumption.

How can I ensure the reliability and trustworthiness of an electrical steel supplier in China?

To ensure the reliability and trustworthiness of an electrical steel supplier in China, it’s important to build a rapport and ask the right questions at the right time. Find out where the factory is located, as this can impact logistics and visits. Also, check if the supplier provides services such as material sourcing, fabrication, and customized solutions. Sampling and testing the products can also help verify their quality.

What are the potential risks and challenges associated with sourcing electrical steel from Chinese suppliers?

One of the main risks is the potential for overcapacity in the electrical steel sector, which could lead to market saturation. Experts warn that unchecked production growth might result in overproduction, especially in high-end products. Additionally, managing capacity carefully and ensuring a balance between supply and demand is crucial for sustaining growth in the industry. Keep an eye on industry policies and adjustments made by regulatory bodies to manage capacity.
