Stainless Steel 321H Foil

Stainless Steel 321H foil is the improved version of 321 grade material that is used in those areas where higher strength and resistance to the sensitization is required at the elevated temperature. The ‘H’ that is appended to the 321H means that the carbon content is higher than that of the normal 321 and this improves the mechanical properties of the alloy in a manner that makes it suitable for use in rather harsh conditions.
