Stainless steel plates are available in a variety of grades to suit different industrial applications. The most common grades include Austenitic, Duplex, Martensitic, and Ferritic, offering a range of mechanical properties and resistance to corrosion. Special grades such as 310S, 309S, 317L, 904L, Duplex 2005, and 230 are also available, each offering specific advantages like higher heat resistance or superior corrosion resistance.These plates are available in thicknesses ranging from 3 mm to 100 mm, with widths between 1000 mm to 3200 mm and lengths ranging from 2438 mm to 3048 mm, 6096 mm, or extending up to 13500 mm for larger applications. The plates come with a No.1 finished surface, which is ideal for many structural, architectural, and industrial uses. The materials meet strict standards such as ASTM A240 and ASME SA 240, ensuring high-quality performance in demanding environments.Additionally, the plates conform to NACE MR 01-75 standards, which makes them highly resistant to sulfide stress cracking, making them suitable for use in sour service environments. The plates are certified according to EN 10204 3.1, ensuring they meet the required specifications and offer prime material quality.These stainless steel plates are widely used in industries such as construction, architecture, chemical processing, automotive, and food manufacturing. Their resistance to corrosion, high temperatures, and mechanical stress makes them perfect for use in structures, tanks, pipes, reactors, facades, and more. Whether it's for high-stress environments or corrosive conditions, stainless steel plates offer versatile, durable solutions.

These types of steel are some of the most regularly specified and have come to represent the embodiment of the basic stainless product. They are part of the 300 Series of steels (as defined in SAE specifications) which covers a range of austenitic chromium-nickel alloys. They are also known as 18/8 stainless due to their chemical composition which includes approximately 18% chromium and 8% nickel by weight. The steels are easy to form, weld, and fabricate and their resistance to corrosion from, amongst other things, acids naturally contained in food has resulted in them being used widely in the food and drink processing industries.
Type 304 and Type 304L have very similar chemical and mechanical properties and are often included on a single material test certificate when the actual properties of a stainless steel plate meet the criteria of both types. This is a very common occurrence. Type 304L is a variation of Type 304 and has a lower carbon content which improves weldability and lowers the risk of reduced corrosion resistance around the weld. Type 304L also has a slightly lower yield and tensile strength than Type 304.
As with most steel plate products, a number of different designations are used for these steels:

These steels are the second most regularly specified stainless steels after Type 304 and are part of the SAE defined 300 Series which encompasses a range of austenitic chromium-nickel alloys. Austenitic stainless steels like Type 316 are widely available, have good general corrosion resistance, good cryogenic toughness, and excellent formability and weldability.
Type 316 has 2-3% Molybdenum included in its chemical composition which prevents specific forms of corrosion and generally enhances its corrosion resistance. Type 316 is often referred to as “marine grade” stainless due to its increased resistance to chloride corrosion compared to Type 304 making it a very suitable material for use in salt water environments.
Type 316L is a variant of Type 316 and differs by having a lower Carbon content as well as slightly lower yield and tensile strengths. Type 316L offers improved weldability and also reduces the possibility of lower corrosion resistance around welded areas.
