Stainless Steel 904L Fasteners

SS 904L Plain Washer, UNS N08904 Bolt, Werkstoff Nr. 1.4539 Stud Bolt, ASTM A673 Stainless Steel 904L Fasteners, Stainless Steel 904L Hex Bolt, UNS N08904 Hex Nut, Werkstoff Nr. 1.4539 Allen Bolt, Din 1.4539 Spring Washer.

An austenitic and non-austenitic type of stainless steel is known as 904l. This Stainless Steel 904L Fasteners has a low carbon content, indicated by the letter l following the grade number. These fasteners have a low carbon content, which makes them resistant to corrosion caused by welding and, consequently, prevents intergranular corrosion. Copper is added to this high-alloy stainless steel grade alloy to make it more resistant to reducing solid acids such as sulfuric acid. It is done so that the grade can be used in applications exposed to such acids. 904l bolt nuts also have other characteristics, such as high formability, durability, and weldability.

Grade 904l is non-magnetic by nature, it can be used in situations where the non-magnetic nature of the material may be beneficial to the product being designed. 1.4539 bolts have high nickel and molybdenum content, which contributes to excellent resistance to crevice and stress corrosion cracking corrosion. This resistance is possible due to the superior resistance to crevice corrosion of the Din 1.4539 Bolt. Despite this, 904l grade bolts are susceptible to breakage due to stress-related cracking, which is particularly likely to occur in chlorine settings. Although fasteners of stainless steel 904l grade have strong oxidation resistance, this grade loses structural integrity at temperatures above 400°c.

About Stainless Steel 904L Fasteners

Din 1.4539 Nut Manufacturer, ASTM A673 Stainless Steel 904L Fasteners Manufacturer, ASME SA673 SS 904L Threaded Rod Stockist, UNS N08904 Bolt Supplier, Werkstoff Nr. 1.4539 Allen Bolt Supplier, SS 904L Hex Bolt Stockist.

Bolts made of alloy 904l stainless steel can be solution-treated between 1090 and 1175 degrees Celsius, followed by a rapid cooling process to quench the fastener. Grade 904l should be cold-worked before solution treatment to obtain the best resistance to stress cracking. These UNS N08904 Threaded Rod have a total carbon content of 0.02%. In addition to acetic, phosphoric, and sulfuric acid manufacturing sites, 904l screws are used in pipeline systems, gas scrubbing plants, oil refinery parts, pollution control equipment, seawater cooling devices, heat exchangers, bleaching systems, and pollution control equipment.
