304 ( 1.4301) QUALITY STAINLESS STEEL

Astm 304 (American Society for Testing and Materials)

EN 1.4301 (European Norm)

Class : Austenitic Stainless Steel

It is the quality standard with the widest usage area of ​​the stainless class.
High weldability, compatibility with cold forming,
It is widely used due to its strength and corrosion resistance.

Oxidation resistance is max.870ᴼC.

Chemical Composition;

(Chrome) Cr % 18-20

(Nickel) Ni 8-10.5%

Carbon (C) 0-0.08%

316 ( 1.4401) QUALITY STAINLESS STEEL

Astm 316 (American Society for Testing and Materials)

EN 1.4401 (European Norm)

Class : Austenitic Stainless Steel

It is the most widely used stainless steel after 304 quality.
Thanks to the Molybdenum in its content, its corrosion resistance reaches high levels.
Corrosion resistance is stronger in environments containing chloride and high humidity. Oxidation resistance is max. It is 1090ᴼC.
It is recommended to use between 425ᴼ-860ᴼC in high temperature continuous use areas.

Chemical Composition;

(Chrome) Cr % 16-18

(Nickel) Ni 10-14%

Carbon (C) 0-0.08%

Molybdenum (Mo) 2-3%

DUBLEX ( 1.4462 ) QUALITY STAINLESS STEEL

Astm 2205 (American Society for Testing and Materials)

EN 1.4462 (European Norm)

Class : Ferritic - Austenitic Stainless Steel

Duplex grade stainless steels, compared to 304 and 316 grades, contain both austenitic and ferretic stainless steel properties.
shows a much higher corrosion resistance.

Compared with ferritic stainless steels, it has the advantage of increased hardness and corrosion resistance,
Compared to austenitic stainless steels, it provides superiority with an increase in breaking strength.
Oxidation resistance max. Since it is limited to 300ᴼC, it is not recommended to use at temperatures above.

Chemical Composition;

(Chrome) Cr 21-23%

(Nickel) Ni 4.5-6.5%

Carbon (C) 0-0.03%

Molybdenum (Mo) 2.5-3.3%
