Selection of grade: 304, 316L, 430

Decorative Stainless Steel Sheet is usually in Grade 304, which is sufficient to prevent corrosion. Grade 316 should be used near the seacoast. Low carbon versions of these grades(304L/316L) should be used when parts are to be welded. 430 is a slightly lower grade than the 300 series and is commonly used for applications when the metal needs to hold a magnet.

304 stainless steel sheet is the most widely used stainless steel, is a versatile, anti-rusting and heat resistant steel for general use.304 stainless steel sheet has numerous applications in architectural, industrial, commercial and transportation applications for its durability and high resistance to wear and scratching. 304 stainless steel sheet is austenitic, meaning it will not attract or hold a magnet in normal condition.

316L has better overall corrosion resistant properties than Grade 304, 316L stainless steel sheet metal, also called marine grade stainless steel, is used primarily for its increased resistance to corrosion. The “L” means that the carbon content of the alloy is below 0.03% which makes the 316L stainless steel sheet preferable for welding. 316L stainless steel sheet is austenitic, meaning it will not attract or hold a magnet in normal condition.

430 stainless steel sheet is a slightly lower grade than the 300 series and is commonly used for applications when the metal needs to hold a magnet, which the 300 series does not. 430 stainless steel sheet is more susceptible to corrosion since it does not contain nickel or molybdenum like the 300 series. This metal will hold a magnet, but not act as a magnet.
