Stainless Steel Plate

Alloy 904L stainless steel plate in thicknesses from 3/16″ through 2″. Alloy 904L (UNS N08904) is a superaustenitic stainless steel designed for corrosion and pitting resistance in a wide range of process environments.

304/304L stainless steel plate is one of the most versatile and widely used stainless grades. Due to its lower carbon content and higher chromium composition, this grade is among the best in its class for strength, corrosion resistance, and formability.

When the chromium content of the alloy is below a minimum of 12%, for example in the aerospace industry, the term “corrosion resistant steel” is used. Stainless steel comes in different grades and surface finishes, depending on where it is used.

Stainless steel is an iron alloy containing at least 10.5% chromium. Chromium produces a thin layer of oxide on the surface of the steel, called a “passivation layer”.

Stainless steel also contains varying amounts of carbon, silicon and manganese. Other elements, such as nickel and molybdenum, can be added to impart other useful properties such as enhanced formability and enhanced corrosion resistance.

Grade 304L is widely used in the manufacturing industry and all standard welding techniques can be used for 304L plate and 304L pipe. The “L” in 304L stands for “low carbon content” and indicates a maximum carbon content of 0.035%. The “H” in 304H stands for “High Carbon Content”, which means that the carbon content is not less than 0.04% and not more than 0.10%.

SS 304, SS 304L, SS 316 and SS 316L stainless steel sheets are the most popular and economical stainless steel grades. Stainless steel 304/304L plate and stainless steel 316/316L plate as well as duplex stainless steel plate have good corrosion resistance to many chemical environments as well as marine and industrial exposures.

304 Stainless Steel Plate has very good formability and can be readily welded by all common methods. 304/304L dual certified.

304 Stainless Plate may become slightly magnetic when worked and is not heat treatable.
