Stainless Steel Sheet Types

Stainless steel sheet is available in type 304 and type 316.

Stainless steel sheet types. Aisi 304 304l astm a240 ams 5513 5511. The letter l after a stainless steel type indicates low carbon as in 304l. 276 is a family of iron based alloys that contain a minimum of approximately 11 chromium. 316 stainless sheet is widely used in marine and highly acidic environments underwater equipment surgical tools food and pharmaceutical applications the addition of molybdenum increases the corrosion resistance of 316 stainless over the more economical 304 grade.

The second most common grade after 304. This type of stainless sheet thickness provides excellent corrosion resistance for both industrial and marine applications. Ryerson stocks many varieties of stainless steel sheet including 304 stainless steel the most popular of the stainless steels. 3 a composition that prevents the iron from rusting as well as providing heat resistant properties.

Also known as marine grade stainless steel due to its increased resistance to chloride corrosion compared to type 304. There are countless variations of stainless steel that you could potentially use for a custom wire basket or tray. The carbon is kept to 03 or under to avoid carbide precipitation. 304 stainless sheet offers good corrosion resistance to many chemical corrodents as well as industrial atmospheres and marine environments.

Carbon in steel when heated to temperatures in what is called the critical range 800 degrees f to 1600 degrees f precipitates out combines with the chromium and gathers on the grain boundaries. Picking the right grade of stainless steel requires knowing what your options are. 304 stainless steel sheet is the most popular and economical of the stainless steels. Type 304 can be easily roll formed or bent and its excellent corrosion resistance and weldability make it one of the most popular grades.

These steels can be divided into three groups based on their crystalline structure. Type 316 is a high corrosion resistance alloy providing greater resistance to pitting type corrosion. For food and surgical stainless steel uses. Stainless steels generally contain between 10 20 chromium as the main alloying element and are valued for high corrosion resistance.

With over 11 chromium steel is about 200 times more resistant to corrosion than mild steel. Alloy addition of molybdenum prevents specific forms of corrosion. 316 316l stainless steel sheet is a popular grade of stainless where superior corrosion resistance is of primary importance. Each formulation of stainless steel alloy has its own unique properties for tensile strength melting point oxidation resistance and corrosion resistance.

Another popular grade is 316 stainless steel which is used in. To make an informed decision when purchasing food grade stainless steel equipment you should understand the major elements in the alloy the different grading systems and the main types of stainless steel.
