Printable PDF: 302 Stainless Steel Alloy Data Sheet
Alloy represents an excellent combination of corrosion resistance and fabricability. Past users of 302 stainless are generally now using 304 alloy since AOD technology has made lower carbon levels more easily attainable and economical. There are instances, such as in temper rolled products, when 302 alloy is preferred over 304 since the higher carbon permits meeting of yield and tensile strength requirements while maintaining a higher level of ductility (elongation) versus that of the lower carbon T304. The true 302 melt is rare as most are using 304 to apply as 304 and 302 applications. All 304 can qualify as 302 since it is a subset of 302 however not all 302 can be 304.

Additional Information on 302 Stainless Steel Alloy
When you are looking for high-quality stainless steel, specifically 302-grade stainless steel, then ESM Hampshire Mill has got you covered.
Stainless steel 302 is often used in making items such as high-grade food-processing equipment, specifically found in most restaurants. Furthermore, you can find it in the creation of utensils like ladles and spatulas.
It is also used in the automotive industry, for things like trim. However it is very versatile, and it can be used in a variety of industries for multiple applications, including the fabrication of small items such as wires, springs, and washers.
At ESM Hampshire Mill, we understand that you need exactly the right steel with its particular properties, especially when picking the wrong type can be dangerous. This version of stainless steel comes in a Chromium or Chromium-Nickel base. It generally comes in sheets, strips, or wire. And we can deliver it to you how you need it and when you need it.
This type of steel is not hardened by the use of heat but by cold working the material. You will find that stainless steel 302 has a better ability to reduce corrosion than that of its neighbor 301. To keep the corrosion resistance in place, however, you want to make sure that your forgings are annealed completely.
When you cold-work this type of stainless steel you will find that it increases in hardness. Normally, 302 stainless steel is non-magnetic. As you cold-work with it, however, you may discover that it can become slightly magnetic at that point.
One of the best things about stainless steel 302 is that it can be formed into almost any shape that you desire. It will harden very quickly so it may be necessary to anneal as you form it into its desired shape.
There are several ways that 302 stainless steel can be welded. You can use gas fusion, Tig weld, electrical resistance, or electrical arc. We can advise you on how to work with the various stainless steels that we can deliver for you. This way, you will get exactly what you need and you can be more productive.
The chemical composition of any metal that you work with can be critical. This specific version of stainless steel is composed of seven different elements. They are Chromium at about 18%, Nickel at 8 -10%, Manganese at 2%, Silicon at 1%, Carbon at .15%, Sulfur at .03%, and Phosphorus at .045%.
If you order your stainless steel 302 from ESM, you will be in good hands. We can also provide a wide variety of other steels including 305 stainless steel, 347 stainless steel, and 409 stainless steel. We make Stainless Steel Precision Strip Coils and offer custom finishes as well.
Here at Elgiloy Specialty Metals, a Stainless Steel Precision Rolled Products Division, we look forward to hearing from you and learning how we can serve you better. We aim to innovate our technology and processes so that we can continue to deliver high-quality products at competitive prices.
You are at the center of what we do, so please let us know what you need and we will provide advice, information, and high-quality products.
