1/17/2024 0 Comments 304 stainless composition![]() ![]() Type 304L should be specified for welded applications as the low carbon version eliminates chromium carbide precipitation and enhances the corrosion resistance in the as-welded condition. The most commonly used stainless steel alloy in the world, 304/304L stainless steel offers a great mix of strength and corrosion resistance without being. Type 304L can be dual certified as 304 when the composition meets the lower carbon limit of 304L and the slightly higher strength levels of 304. Type 304/304L is non-magnetic in the annealed condition but may become slightly magnetic as a result of cold working. Higher strength, cold-worked conditions can also be specified for Type 304/304L for spring type applications. Higher nickel versions can be specified to enhance multi-stage deep drawing characteristics. These grades can be specified in the annealed condition where they have very good formability. Type 304/304L is a versatile, general purpose stainless steel with good resistance to atmospheric corrosion, and to many chemicals and food and beverages. Type 304/304L is the modern version of “18-8” stainless steel containing approximately 18% chromium and 8% nickel and is the most commonly specified stainless steel used throughout the world. Alloy Designations S tainless stee l grade 303 also corresponds to the following standard designations and specifications: Corrosion Resistance of Stainless Steel Alloy 303 Sulphur additions to the composition act as initiation sites for pitting corrosion. Alloy 304 a T-300 series stainless steel austenitic, which has a minimum of 18 chromium and 8 nickel.

Note: Maximum “ ≤“, unless range (Min-Max) or minimum (≥) is indicated. SS304 stainless steel has lower corrosion resistance than SS316 and slightly higher than SS302. Its nominal composition is 18 chromium and 8 nickel, so it is also called 18/8 stainless steel. For its compositions of 18 chromium and 8 nickel, 304 stainless steel is also. The following table lists the chemical composition of stainless steel alloys, including austenitic SS 304, 304L 316, 316L, 321, 303, 302, 301, 904L, 201, etc., martensitic SS 440A, 440B, 440C, 420 etc., ferritic SS 430, duplex stainless steel 2205, 2507, 329, etc. SS 304 is the abbreviation of Stainless Steel 304, which is the most widely used austenitic chromium-nickel stainless steel. Essentially, Grade 304 is an austenitic chromium alloy which is also known as an 18/8 stainless as the make-up of the steel is 18 chromium and 8 nickel. Type 304 is the most widely used austenitic stainless steel for casting. Therefore, stainless steel metal generally has a Chromium content of minimum 10.5%. Only when the Cr percentage composition reaches a certain value, the steel has corrosion resistance. The elemental chemical composition of stainless steel is mainly composed of Ferrum (Fe) and Chromium (Cr), other alloy elements in the chemical composition also include Carbon (C), Silicon (Si), Manganese (Mn), Phosphorus (P), Sulfur (S), Nickel (Ni), Molybdenum (Mo), Titanium (Ti), Nitrogen (N), and Cuprum (Cu), etc. Stainless Steel Chemical Composition Chart Mechanical Properties at Room Temperature Tensile Strength, MPa, 600, 515 Proof Strength, (Offset 0.2 ), MPa, 310, 205 Elongation (Percent in 50mm), 60. ![]()
