EN 1.4547 / UNS S31254 Stainless Steel Sheet
Top EN 1.4547 Stainless Steel Sheet Manufacturer in China
The UNS S31254 grade steel sheet is also known as 1.4547. It is a high-alloyed, super-austenitic steel with a remarkably high resistance to corrosion in aggressive chloride environments, such as seawater. Stainless steel, with its interruption and distinctive cavitation corrosion resistance, is thus best suited for use in marine, chemical, and offshore activities. The possibilities of this are ordinary in terms of industrial applications of steel, considering it is fully weldable and easily formable.
