JIS C2553 27G130 Introduce
JIS C2553 27G130 has good corrosion resistance due to its high levels of silicon and chromium. The silicon helps to form a protective rust which prevents surface corrosion. The chromium helps to form a hard outer layer that prevents rust from forming beneath the surface. Additionally, JIS C2553 27G130 is anodized, which further improves its corrosion resistance by creating an additional layer of protection.
Smelting temperature:1235°C - 1822°C
Application:Fully processed state to deliver cold rolled grain oriented electrical steel strips and sheets
