0.03mm hand tearing steel set the limit of specification accuracy

Recently, we successfully produced 0.049mm wide ultra-thin precision stainless steel strip, and made successful mass production of 1m wide, 0.03mm thick "hand tearing steel". The 30000 ton automobile steel production line, which has been put into operation for a short time, has reached the acme of specification precision. This is also the largest "hand torn steel" product with the same thickness and width in the world.

The production technology of stainless steel precision products is recognized as a cutting-edge technology in the field of stainless steel cold rolling in the world.

The production technology of stainless steel precision products has very strict requirements in thickness precision, plate type requirements, surface roughness, gloss, mechanical properties, hardness and strength.

The ultra-thin precision stainless steel strip below 0.05mm, commonly known as "hand tearing steel", is the most difficult and the most valuable stainless steel product at present.

With the rapid development of new energy, electronic communication and other industries, the application prospect of "hand torn steel" is more and more extensive. High end mobile phone folding screen, photovoltaic power generation flexible substrate and so on all need to use hand tearing steel material.
