SAE 304 stainless steel temperature strength and thus the specified minimum tensile properties of 304L are lower than for 304. However, nitrogen also has a strong influence on room temperature strength and a tiny addition of nitrogen produces 304L with the same tensile strength as 304. Thus, practically all 304L is produced as dual certified 304/304L, meaning it meets the minimum carbon content of 304L and also meets the minimum tensile strength of 304. SAE 304 stainless steel SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18–20%) and nickel (between 8–10.5%) metals as the main non-iron
Stainless steel plates (Cala Galdana bridge), or reinforcing bar (Champlain Bridge) Stainless steel is a modern trend for roofing material for airports due to its low glare reflectance to keep pilots from being blinded, also for its properties that allow thermal reflectance in order to keep the surface of the roof close to ambient temperature. The Hamad International Airport in Qatar was built with all stainless steel roofing for these reasons, as well as the Sacramento International Airport in California. Stainless steels have a long history of application in contact with water due to their excellent corrosion resistance. Applications include a range
