Stainless Steel Plates

Stainless steel 441 sheets are ferritic stainless steel with niobium stabilization that has excellent corrosion resistance. 441 stainless steel sheet is a niobium-stabilized ferritic stainless steel. It has good high-temperature strength as well as resistance to creep, oxidation, and corrosion. In high-temperature and gas exhaust environments, this stainless steel grade provides some of the best strength. One disadvantage of this stainless steel grade is that it has lower weld quality when compared to the other 400 stainless steel grades. It cannot be heat treated.

Our grade 441 stainless steel plate is primarily considered a general-purpose chromium stainless steel and is used for chromium-specific applications. Stainless Steel 441 Plates have excellent erosion resistance in a wide range of eroding chemicals such as sulfuric, nitric, and phosphoric acids. Our entire product line of 441 SS Sheets has high compressive strength and can be used in a variety of applications. Furthermore, our quality control team thoroughly inspects 441 Stainless Steel Plates against strict quality parameters to ensure their perfection and proper finishing.

Stainless Steel 441 sheets are moderately formable and have excellent creep resistance. These sheets’ higher oxidation and corrosion resistance increase their popularity. SS 441 sheets are useful in a variety of industries due to their high tensile strength, toughness, and longer workability. Multiple tests and inspections were performed on SS 441 sheets, including flattening, flaring, radiography, ultrasonic, and third-party analysis. All of these tests contribute to higher product quality.

The SS 441 sheets offer high-temperature strength as well as the ability to work in an exhaust gas environment. Furthermore, the material has deep drawing abilities as well as brightness. Titanium in SS 441 contributes to their good stabilization and excellent resistance to stress corrosion cracking. Welding of SS 441 sheets is simple using common fusion and resistance welding processes. SS 441 Sheets are available in a variety of sizes, thicknesses, and finishes. It has excellent pitting corrosion resistance and welding capabilities.

Typically found in gas processing equipment. Shafts and pumps are also common applications for these products. SS 441 sheets are widely used in heat exchangers and condensers. Chemical equipment frequently employs Stainless Steel 441 Sheets. Customers can easily obtain it as per their specifications because it is available in a variety of sizes and shapes. Alloy 441 Sheets combines copper and molybdenum with iron for significantly improved resistance to corrosive acids such as sulfuric acid. Alloy 441 Plates is high-quality austenitic steel with moderate to high corrosion resistance.

Uses and Purpose of 441 Stainless Steel Plates

Ferritic steel with respectable chromium content and no hardenability is known as SS UNS S44100. The advantages of this steel's mechanical properties, including its durability and corrosion resistance, are widely known. It can be used for several chemical processes because it can withstand nitric acid well. For use in automatic screw machines, Grade  of 441 stainless steel plate is normally supplied in the form of a bar. Grade 441 has the same characteristics as Grade 441 even though it contains molybdenum. Its corrosion resistance is increased by the inclusion of molybdenum. In stainless steel UNS S44100 plates, all ferritic grades exhibit excellent resistance to stress corrosion cracking.

Numerous chemicals, as well as several organic acids and nitric acid, can be tolerated by SS 441 Plate. Corrosion resistance is greatest in a well-polished or buff state. Its resistance to pitting and crevice corrosion is comparable to grade 304. Because it is an evaluated sulfur-free machining grade, 441 is less resistant to pitting and crevice corrosion than grades that are not.

Excellent corrosion resistance, formability, and useful mechanical properties are all offered by  441 stainless steel plates.  441 stainless steel plates are suitable for use in a variety of chemical applications because of their resistance to nitric acid. Excellent stress corrosion cracking resistance and good corrosion resistance to a number of chemicals, including nitric acid and organic acids, are both characteristics of ASTM A240 SS 441 plates and plates.

SS UNS S44100 plates can withstand temperatures of up to 870℃ and up to 815℃ in constant use. These Plates are used in linings for dishwashing machines, supports and fasteners for the elements, panels for refrigerator cabinets, wire lashing, automobile trim, and trim rings for stoves and chimney liners.
