These stainless steel plates have some unique mechanical properties resulting from their chemical composition. Mechanical Properties of 309, 309S and 309H Stainless Steel Plate They also contain 2.0% manganese and 1.0% silicon, 0.045% phosphorous and 0.03% sulfur. 309S is made up of no more than 0.080% carbon and 309H stainless steel is made up of between 0.04% and 0.10% carbon. 309 is comprised of at most 0.20% carbon. The only chemical difference between 309, 309S and 309H stainless steel plate lies in the carbon content. Chemical Composition 309, 309S and 309H Stainless Steel Plate Contact Penn Stainless Products directly for more information or custom sizes. This type of stainless steel plate is available in plate in plate mill plate in a variety of mill sizes. It is available in coil plate lengths of 96 “, 120”, 144”, but custom lengths are also available per customer request. It can be purchased in thicknesses ranging from 0.188” to 1.5”. This plate is available for purchase at Penn Stainless Products in plate mill plate, and coil plate. 309H contains more carbon than 309, this results in an enhanced creep resistance. 309H differs from 309 plate in the amount of carbon as well. 309S contains much less carbon which minimizes carbide precipitation and improves weldability. The main difference between 309 and 309S stainless steel lies in the carbon content. This type of stainless steel also provides excellent strength at room and elevated temperatures. Due to their high chromium and nickel content, these grades of stainless steel plate are highly corrosive resistant and have outstanding resistance to oxidation as well as excellent heat resistance. It is found everywhere, from the springs in tanks to the fuel lines carrying vehicle exhausts.309, 309S and 309H Stainless Steel Plate Overviewģ09, 309S and 309H stainless steel plate are chromium-nickel austenitic stainless steel grades that are commonly used in environments with elevated temperatures. Since WW2, stainless steel has also played a key role in the defense sector. A good quality piece of stainless steel serves as a buffer against the damaging effects of wind and water, maintaining safety and stability. When it comes to infrastructure, the corrosion resistance of stainless steel helps extend the lifespan of structural and architectural projects. In the medical industry, stainless steel is found in nearly all the equipment that doctors use in their work as well as the many of the small, intricate parts of hospital machinery (such as the EKG or ECG) for monitoring patients. These applications can include food handling/processing (i.e., kitchen sinks, cutlery), medical instruments (i.e., thermostats), hardware, appliances, and structural/architectural uses (i.e., bridges, airport roofs). Unlike ordinary steel, stainless isn’t prone to corrosion, rusting or staining from water exposure – giving it many versatile applications. The most common of these steps include hot rolling, cold rolling, annealing, descaling/ pickling, cutting and finishing. You can have everything from stainless steel tubing and stainless steel pipes to a stainless steel bar and stainless steel sheet.ĭepending on which grade or shape is being produced, a piece of stainless steel may go through some processing steps multiple times before reaching the desired appearance or characteristics. Stainless steel also comes in many different shapes and dimensions. There are more than 100 grades of stainless steel – most are classified into five groups in the family of stainless steels: The exact composition is strictly measured and assessed throughout the alloying process to ensure the steel demonstrates the required qualities. Other elements can be added to increase corrosion resistance (nickel) and formability (molybdenum). This type of steel also contains varied amounts of other elements such as carbon, silicon and manganese. Once stainless steel is put into service, it does not need to be treated, coated or painted.īesides resistance to corrosion, stainless steel is known for its: This layer prevents corrosion from occurring on the steel surface the greater the amount of chromium in the steel, the greater the corrosion resistance. The chromium content produces a thin chromium oxide film on the steel’s surface called a passivation layer. Stainless steel is an iron alloy that has a minimum chromium content of 10.5%.
