Within the existing metallurgical families, we have the 300 series stainless steel family. This family, with an austenitic crystalline structure, has various types of alloyed materials. Next, we are going to get to know AISI 316 stainless steel from the 300 series, which, together with AISI 304 stainless steel, is one of the most used materials in the manufacture of accessories for our products:
It is a non-magnetic austenitic alloy with traces of molybdenum. This element allows the increase in resistance to corrosion in the material. At a general level, it has properties similar to those of the AISI 304 alloy.
With the naked eye, the differences between AISI 304 alloy and 316 alloy are difficult to see. The most notable feature in our products is the finish, which ranges from satin in AISI 304 to bright in 316. But, at the level of structure and composition of materials, there are marked differences for manufacturers.
Molybdenum is the element that makes the difference in obtaining the AISI 316 alloy. This component improves resistance to corrosion in saline environments, which gives it an extra for applications near maritime and underwater areas.
Of course, this does not imply that Alloy 304 is poor at corrosion control, but this added element allows 316 to be used safely in environments where 304 might not last as long.
It is a material used in extreme applications related to maritime activities. Under these conditions, it has greater durability than AISI 304 alloy, although this characteristic raises its price.
It is also widely used in the food industry, in environments with the presence of chloride.
Other fields of application are: laboratory equipment, architectural elements, chemical and fishing industry, among others.
