Type 304L is a low carbon version of the 304. Used on heavy parts to improve weldability. Some products, such as plates and pipes, may be available as "dual certified" materials that meet both 304 and 304L standards.
Stainless steels are a group of corrosion-resistant steels with a chromium content of 10.5% or more. Among the various qualities, 304L stainless steel stands out for its combination of excellent properties. The "L" in 304L stands for its low carbon content, which increases resistance to weld sensitization and reduces the risk of corrosion in certain environments. This variety is commonly used in a wide range of industries, from construction to food processing.
Prosaic Steel & Alloys is a known supplier and manufacturer of SS 304L Patta, which is a good general all-purpose stainless grade. ASME SA 240 Type 304L Patta Patti is a low carbon variant of 304 and more suitable for welding. The low carbon in ASTM A240 Stainless Steel 304L Patta Patti may be easier to shape and form, which in turn may also affect the levels of residual stress left the steel after is forming and fitting up for welding. AISI 304L SS grade is used almost exclusively for parts requiring machining, welding, grinding, or polishing where good corrosion resistance is also required.
ASTM A 240 Stainless Steel 304L Patta is resistant to carbide precipitation and can be heated into this temperature range. Typical Applications of ASTM A 240 Stainless Steel 304L Patta Patti are: Moisture separator reheaters, Feedwater tubes, Stator bars, Heat exchangers and so on. ASME 240 Type 304L Patti is also include in other applications such as beer barrels, bellows, chemical equipment, coal hopper linings, cooling coils, cryogenic vessels, dairy equipment, evaporators, flexible metal hose, food processing equipment, hypodermic needles, nuclear vessels, oil well filter screens, refrigeration equipment, paper industry, pressure vessels, sanitary fittings, valves, shipping drums, spinning, still tubes, textile dyeing equipment, etc. Buy 304L Stainless Steel Patta Patti at very competitive price from us.
Due to its lower carbon content, SAE 304L has a lower tensile strength of 85 KSI compared to approximately 90 KSI for SAE 304. Additionally, SAE 304L has a yield strength of approximately 35 KSI, while SAE 304 has a yield strength of 42 KSI.
SS 304 contains a maximum carbon content of 0.08%, while SS 304L has a maximum carbon content of 0.03%. The lower carbon content in SS 304L helps to minimize the formation of chromium carbides during welding, which can lead to intergranular corrosion and reduced corrosion resistance.
SS 304L is specifically designed to be more weldable than SS 304. The lower carbon content in SS 304L reduces the likelihood of carbide precipitation at the grain boundaries during welding, known as sensitization. Sensitization can cause intergranular corrosion and compromise the corrosion resistance of the material. Therefore, SS 304L is often the preferred choice for applications involving welding or where the material will be subjected to high temperatures.
Both SS 304 and SS 304L offer excellent corrosion resistance in a wide range of environments, including atmospheric conditions and many corrosive media. However, the reduced carbon content in SS 304L provides better resistance to intergranular corrosion in welded areas. This makes SS 304L a suitable choice for applications that involve welding, such as fabrication of pipes, tanks, and other equipment.
SS 304L exhibits higher strength and improved creep resistance at elevated temperatures compared to SS 304. This makes SS 304L a preferred choice for heavy gauge components or applications where the material will be exposed to higher temperatures.
SS 304 and SS 304L are widely used in various industries, including food processing, chemical processing, pharmaceuticals, and architecture. SS 304 is commonly used in applications that do not involve welding, such as kitchen equipment, appliances, and decorative elements. On the other hand, SS 304L is more commonly used in welded components, such as pipes, tanks, and heat exchangers.
304L SS Patta Patti often eliminates the necessity of annealing weldments except for applications specifying stress relief. Grade 304L Stainless Steel Patta is good in corrosive environments as in paper and chemical industries and cryogenic services. Type 304L Stainless Steel Patti is non-magnetic in the annealed condition but may become slightly magnetic as a result of cold working or welding.
