Stainless Steel is a group of alloy steel comprising 10 to 30% of chromium. When associated with low carbon content, chromium exhibits excellent oxidation and high temperature. Other elements, such as nickel, molybdenum, titanium, aluminum, niobium, copper, nitrogen, sulfur, phosphorus, can be added to improve corrosion resistance, oxidation resistance, and impart special properties. Stainless steel is the material that is best known for its resistance to corrosion, it can be used for a wide range of applications, having too many grades, on the other hand, necessitates selecting the best.
Grades of Stainless Steel
These stainless Steel Plates are available in a variety of grades, each stainless steel grade has a slightly different chemical composition and, as a result, a distinct physical appearance.
Stainless Steel 300 series
Stainless Steel 300 series is austenitic, with additions of 18 to 30 % Chromium and Nickel configurations ranging from 6 to 20 %. It is made of solid iron with face-centered cubic crystals. The Stainless steel 300 plate composition makes it particularly useful in the construction, automotive, and aerospace industries. These plates can only be hardened by cold working methods because it can withstand extremely high temperatures.
Stainless Steel 301 series
Stainless Grade 301 Plates are attractive and pliable, with a max strength and corrosion-resistant composition. Grade 301 Plates of stainless steel are frequently used for decorative structural applications due to their high malleability and abrasion resistance.
Stainless Steel 304 series
Stainless steel Grade 304 Plates series is the most popularly used Grade, this grade 304 plate contains 18 Percent of chromium and 8 Percent of Nickel, making it both aesthetically pleasing and durable. Because of their saline sensitivity, these plates can tolerate pit or crevice when used near salt water.
Stainless Steel 316 series
SS Plates of Grade 316, are the second most common steel grade 316 plates that contain 2-3 percent molybdenum. As a result, it is more resistant to saline and thus better suited to coastal environments. Grade 316 stainless steel plate is also used to make a variety of surgical supplies.
Stainless Steel 317 series
Stainless Steel 317 is a modified version of the stainless steel grade 316. These 317 plates are extremely strong and resistant to corrosion. 317 stainless steel is more durable than 304 stainless steel. If constant feeds and low speeds are used, the hardenability of this alloy will be reduced. All common hot working procedures can be used in Grade 317 stainless steel. It is heated to a temperature of 1149 to 1260 degrees Celsius. At extreme temps, this grade has high tensile strength.
Stainless Steel 904L series
SS 904L Plates are non-stabilized Austenitic Stainless Steels grade with copper as part of the alloy. This steel can stand in corrosion from a wide range of acids. It is considered to be a high-cost Stainless Steel Grade. Grade 904L stainless steels can be solution heat-treated at temperatures ranging from 1090 to 1175°C, followed by rapid cooling. These grades can be hardened using thermal treatment. Plates of this grade are commonly used in marine applications, petrochemical industries, and chemical and fertilizer industries, refining sectors, and so on. In general, yield strength, tensile strength, hardness, toughness, creeps resistance, and fatigue resistance, as well as grade, reflect the specific alloy’s durability, quality, and temperature resistance. The grade refers to chemical components, specifically the chromium and nickel percentages.
