Stainless Steel Core for Power Batteries
Purpose: In the field of power batteries, the "stainless steel core" is a key component that performs the functions of support, protection, connection and electrical conductivity in the battery structure. Stainless steel is used due to its advantages: high strength, corrosion resistance and relatively low cost.
In the automotive industry:
1.Application scenarios: Widely used in key automotive component areas such as fuel injection systems, brake systems, sensors, turbocharging lines, and electric vehicle battery cooling tubes.
2.Key requirements: Products must have excellent resistance to high pressure and high temperatures, as well as exceptional fatigue strength and high dimensional stability to adapt to demanding operating conditions.
3.Advantages of Xinliang: The production process and product quality fully comply with the strict standards of the automotive industry, ensuring consistency and reliability.

Product range
We can produce various types of stainless steel tubes with outer diameter from 0.4mm to 16.0mm and wall thickness from 0.05mm to 1.2mm. We have a significant advantage in the production of small diameter tubes and thin-walled tubes, which allows us to fully meet the stringent requirements of the precision manufacturing industry.
