Stainless steel is a term used to refer to any dissimilar metals that are commonly used in industries together with transportation, construction, and even architecture. Two commonly used alloys are 201 and 304. While all stainless steels contain more than fifty percent iron and at least eleven percent chromium, each grade has a dissimilar aggregate of other metals, giving it unique properties, strengths, and weaknesses. Understanding these distinctions will help you choose the definite grade to use for your project.
A dissimilarity of nickel

In order to understand the dissimilarity between these two grades of stainless steel, it is helpful to know why 201 became beloved in the first place. A one point, the price and availability of nickel became prohibitive to the output of 304 grade.
This created an opening in the shop for an alloy that used less nickel and thus would not be branch to price increases as easily. 201 uses a aggregate of chromium, nickel, and manganese that reduces the number of nickel principal for production, this development it economy in normal than the 304 alloy that is most commonly used. How does the decrease in nickel affect the steel?
- 201 grade is stronger than 304; some estimation as much as 30% stronger
- 304 grade, although not as strong, is easier to form and weld than 201
- 201 is not as corrosion-resistant as 304, limiting its practicality in harsh environments
Applications for both
Due to the differences and similarities between the two grades, some of the uses overlap. Both can be found in automobiles, architecture, railways, and even appliances. However, 201 is used more often in food preparing industries, together with cooking utensils, sinks, dishwasher components, and other bistro equipment. 304 can be used in these applications but is also unyielding sufficient to corrosion to be used in maritime environments where it will be exposed to the corrosive seawater. Depending on your needs, you may want to consult with others in your industry to find out which type of steel they are using and how it stands up to the challenges of that industry.
