Most of the industries have a liking for the metal called stainless steel. Well pulling off any work with this metal is easy because of its chromium and iron content. The presence of chromium adds a protective layer on top that fortifies the metal from getting rust. Talking of the categorization of the stainless steel well there are four types in general. Among them, austenitic stainless steel is the most recommended one. It is so because of its brilliant mechanical characteristics and its tolerance to corrosion. Generally, two grades of austenitic Stainless steel mostly used are 316 and 304. To understand more about these two grades we have segregated both of them based on certain elements and factors.
The whole composition
Generally, stainless steel contains both irons as well as chromium. But yes these two grades can differ from each other based on the percentage of these elements. Talking of 304 grade it consists of 18 to 20 percent chromium and nickel content counting to 8 to 10.5 percent. Additionally, it consists of manganese, silicon, iron as well as carbon. On the other hand, 316 grade replicates similar elements like that of 304. However, traces of molybdenum hitting 2 to 3 percent can be found in this grade as well.
Robust and enduring capacity
Both grades of stainless steel are robust and are durable. It is the high content of nickel and chromium that makes these grades tolerant to rust and corrosion.
Power to withstand corrosion
The 316 grade offers increased resistivity when it comes to corrosion. That is because of the molybdenum. Though the molybdenum counts to 2 to 3 percent, still it can help the steel to show its resistivity power when exposed to chlorinated and chloride solutions. Even 316 grade is considered congenial when exposed to salty applications. Well, that is again because of its resistance to corrosion and long-lasting capacity.
Overall price
The 304 grade of stainless steel is considered pretty functional for any kind of sector whether it’s industrial, residential, or commercial. Now it is fairly because of the toughness, longevity, and corrosion tolerance. Besides these, it is affordable which is why industries do prefer this grade of stainless steel. In comparison to that 316 is a bit costlier. However, in terms of reliability, it has more followers because of its long span and more tolerance to vulnerable environments.
General application
It is seen that grade 304 is widely used in crafting daily appliances such as freezers, Air conditioners, stainless steel sinks, stainless steel benches, stainless steel kitchen benches, dishwashers, heat exchanging units, food processors, fasteners, pipes. Compared to this steel grade 316 grade is mostly used for medical pieces of equipment, chemical processors, storage units, refinery tools. Else it is also useful in fabricating types of equipment mostly used in marine ambiance.
Bottom line
Finally, we came up with the detailed segregation of the 304 and 316 steel grade types. Read through the points and consider these carefully before you make the purchase. For more particulars on these, you can even ask for professional assistance as well.
