304 stainless steel round bar
Langsda Metal Products Co.,Ltd supply 304 (UNS S30400 ) are austenitic alloys of stainless steel bars. These alloys are the most familiar and most frequently used alloys in the stainless steel family.
Description
Both 304 stainless steel stainless steel provide a general purpose stainless steel with good resistance to atmospheric corrosion, to many organic and inorganic chemicals and to food and beverages.
The difference between 304 and 304L stainless steel is that 304L has a .03 max carbon and is good for welding whereas 304 has a mid range level of carbon.
304 are austenitic alloys, which means that a nonmagnetic solid solution of ferric carbide or carbon in iron is used in giving this stainless steel its corrosion-resistant properties.
