304L Stainless Steel Fasteners

ASTM A193 SS 304L Bolts and Nuts Manufacturer and suppliers in india

304l stainless steel fasteners are made up of the lower carbon version of the 304 austenitic stainless steel grade. The material has nickel, chromium, carbon, manganese, silicon, sulfur and phosphorus in the composition. The ASTM A193 304l stainless steel bolts are intended for high temperature or high pressure services such as the boilers, heat exchangers, hydraulics, power generation plants and in oil and gas applications. The material can be used to make ASTM A193 or 194 specifications of fasteners.

There are different types of these fasteners such as the bolts, nuts, screws, washers, studs and threaded rods. The SS UNS S30403 nuts and bolts can range in DIN, ASTM, BS and other international standards. The sizes range from M02 to M33. The length of the different fasteners range from 3mm to 200mm and they can be made under custom sizes as well. The DIN 1.4306 screws material is strong and corrosion resistant.

It has 205MPa minimum yield strength and 515MPa minimum tensile strength. The different types such as the 304l stainless steel stud bolts are used in different application types. The applications of the studs are mostly in connecting parts that do not require or cannot have nuts in them. Please feel free to contact us for the different types such as the ss 304l threaded rod and the pricing.
