Special tension leveled/tempered super thin stainless steel
In the recent years we are striving to develop CSP super thin with high tensileness strength coils/sheets at specified hardness such as 1/2H, 3/4H &FH to extra Hard and is capable of reaching 0.04mm super thin plate.
With the cutting-edge metal treatment technique of the mills, we have entered the high-end applications such as engine gasket, hard disc drive, LCD frame, computer fittings, cellular phone case, precision stamping parts, medical instruments., etc.
Our strategic alliance with the mills enables us to adjust manufacturing conditions for each product according to its application and processing by different heat treatment methods.
