A stainless steel grade indicates the attributes of a particular type of this metal. The grades of stainless steel like 304 and 316 are common. Such grades are often represented by a number. To the laymen or new buyers of this metal, the meaning of these numbers may not be clear. Neeraj Raja Kochhar’s latest news has brought to light that better information can be obtained when the number of the SS grade is known. Grades of this metal like 18/10 and 18/8 help in knowing that nickel exists in fine quantities in them. Thus, the products made from these grades will be better suited to environments that have exposure to rusting or corrosion.
On the basis of what Mr. Kochhar, the founder of Viraj Profiles, has explained, more insights can be gained below.
Understanding Stainless Steel Grades and their Numbers
It has been shared by Neeraj Kochhar that the grade of metal like stainless steel hints at its attributes. Knowing about the quality of this particular metal can be easier when its grade is known. In addition, stainless steel’s grade can tell about the metal’s resistance to temperature as well as durability.
In an attempt to explain further about stainless steel grades and their numbers, Neeraj Raja Kochhar’s latest news suggests that they represent the composition of this metal. Thus, when you come across numbers like 18/10, 18/8, etc., you can find out about the elements and their amounts that have been used for composing stainless steel. The composition of SS grades can have elements present in different quantities. These quantities can give a particular grade more or less strength. Likewise, the other attributes of these grades can depend upon the composition.
Stainless Steel Grades 18/10 and 18/8
You may have often heard about the SS grades 18/10 and 18/8. Among the most common grades of this metal, they are at the top. These particular grades are more commonly recognized as grade 304. In the numbers 18/10 and 18/8, “18” indicates the percentage or quantity in which chromium is found in these grades. “10” or “8” can be understood as the quantity of nickel in its composition.
In addition to chromium and nickel, these grades also comprise carbon and iron. While the percentage of carbon is around 0.8, the percentage of iron is around 50. The presence of these alloys in their respective amounts ensures that the grade of stainless steel receives protection from oxidation. With nickel in the composition, this grade becomes quite effective in resisting corrosion. Here, one thing that is noticeable is the role of nickel. On the basis of Neeraj Raja Kochhar’s latest news, it has been observed that when the percentage of nickel is higher in the metal’s composition, the resistance to corrosion significantly increases.
Grade 18/0 of Stainless Steel
18/0 is another grade of stainless steel that has been commonly heard of. It can also be identified as SS grade 430. This grade of SS is formed using alloys like nickel. However, the percentage of nickel in this grade is around 0.75. It should also be known that the grade 430 of stainless steel has a higher presence of chrome. This percentage of nickel being low, the 18/0 grade of stainless steel cannot be expected to provide higher resistance to corrosion. Thus, for uses that do not include rusting, this grade can be a fine choice.
Also, when the purpose of usage does not involve the need for much strength or heat conduction, grade 18/0 should be preferred. Due to its attributes, this SS grade can be purchased at a very affordable price.
Industries that make flatware, as well as kitchen utensils, require the grade 18/0 in bulk. An interesting feature of this grade of stainless steel is that the utensils made from it can be washed using dishwashers. This is mainly due to the fact that nickel doesn’t exist in this grade’s composition in a high amount. Therefore, cleaning these utensils in dishwashers is absolutely safe and requires less time, as can be understood from Neeraj Raja Kochhar’s latest news.

Conclusion
As we read here, stainless steel comes in different grades. These grades are represented by certain numbers. These numbers are given on the basis of the composition of stainless steel. In different grades, the composition can have a higher or lower presence of certain alloys. As Mr. Kochhar has explained, by knowing the number of an SS grade, you can learn more about the attributes of the metal. Based on these attributes, industries should purchase stainless steel. By doing so, the best grade can be chosen. Also, this will help in utilizing that grade’s efficiency.
