A Short Guide to Grades of Stainless Steel

What is the Stainless Steel?

Stainless steel is commonly utilized in the manufacture of cookware, kitchen sinks, and automobiles because it is aesthetically beautiful and corrosion-resistant. The phrase stainless steel refers to a variety of iron-based alloys that include at least 10.5 percent chromium in their composition. Stainless steel comes in over 100 grades, all of which are distinguished by their crystalline structure.

In the 1930s and 1940s, the American Iron and Steel Institute created the first steel grading system. This method was then integrated with one developed by the Society of Automotive Engineers (SAE) International to create a more consistent numbering system. However, today’s steelmakers may employ multiple numbering systems, which can make things more complicated.

The main principle behind grading stainless steel is that it may be categorized into three major groups depending on the crystalline structure of its iron atoms: austenitic, ferritic, and martensitic. Series and grades are further separated into each category. The grades indicate how long an alloy will last, how good it is, and how resistant it is to heat. The numbers after the grade indicate the item’s chemical makeup, especially the amounts of chromium and nickel.

Each stainless steel grade has a somewhat varied chemical makeup and, as a result, a variable physical appearance. Stainless steel comes in a variety of grades:

Stainless Steel 304 Grades

Grade 304 accounts for half of all steel produced on the planet. Grade 304 has an 18% chromium and 8% nickel content, making it both visually beautiful and durable. Because of its saline vulnerability, grade 304 can pit or crevice when exposed to saltwater. 304 stainless steel sheet, 304 stainless steel plate, 304 stainless steel bar, and 304 stainless steel tube are all available in our inventory.

Stainless Steel 316 Grades

Grade 316, the second most prevalent steel, includes 2-3 percent molybdenum. As a result, it’s more saline-resistant and hence more suited to coastal areas. 316 stainless steel is also used to make a lot of surgical supplies. The extremely low carbon version of this grade stainless steel is available from Kloeckner Metals. 316L stainless steel sheet, 316L stainless steel plate, 316L stainless steel bar, and 316L stainless steel tube are among the materials available.

Stainless Steel 317 Grades

At high temperatures, this grade has high tensile strength. It is more corrosion and pitting resistant than stainless steel grades 304 and 316. Grade 317 stainless steel is more costly than most other 300-level grades due to its composition.

Stainless Steel 904L Grades

904L stainless steel is a non-stabilized austenitic stainless steel with copper as part of the alloy. As a result, this steel grade can withstand corrosion from a wide range of acids. However, due to the high cost of this grade of stainless steel, many producers have turned to the lower-cost duplex stainless steel 2205 as a substitute.

Stainless steel is available in a variety of series and grades. It’s critical to select the appropriate stainless steel for your product and environment. Visit our website to learn more about Stainless Steel: https://www.astectube.com/stainless-steel-pipe-fittings-manufacturer-supplier.html
