Stainless Steel Material Options: Bellows & Floats

Austenitic Grade


303
 

Free machining stainless. Used in automatic machining operations. Good corrosion resistance.

304
 

304 Most widely used stainless. Good corrosion resistance with good formability and welding.

304L
 

Low carbon stainless with the same properties as 304 but with superior intergranular corrosion resistance following welding or relieving.

316
 

Better corrosion resistance and higher strength at elevated temperatures than 304. It also has superior creep strength at elevated temperatures. Used in pumps, valves, chemical equipment, and marine equipment.

316L
 

Low carbon stainless with the same properties as 316 but with superior intergranular corrosion resistance following welding or relieving.


Ferrite Grade


416
 

Heat-treatable, free machining stainless used where corrosion is not severe. Resistant against natural food acids, water and basic salts in most atmospheres.


Martensitic Grade


Carpenter
Custom 450
 

Displays the same corrosion resistance as 304 stainless, with two to three times the yield strength. Can be used heat-treated or non heat-treated.


Precipitation Hardening Grade


17-7 PH
 

Excellent mechanical properties at elevated temperatures. Heat-treatable for high strength properties.

AM 350
 

Same properties as 17-7PH with slightly higher capabilities at elevated temperatures. Can be used heat-treated or non heat-treated.


Special Metals


Monel 400
 

High strength and toughness over wide temperature range. Corrosion and oxidation resistance to 1000 degrees F.

Inconel 625
 

Excellent corrosion resistance, formability, and welding properties. Good for cryogenic to high temperatures up to 2000 degrees F.

Hasteloy C
 

Used mostly in chemical environments for resistance against oxidizing agents.
