A high carbon version of the austenitic stainless steel grade 304 makes up Stainless Steel 304H Fasteners. The substance is sturdy, resistant to corrosion, and has outstanding mechanical qualities. Because of the higher carbon content, the austenitic chromium-nickel steel alloy has higher tensile and yield strengths. Due to the grade’s heat-resistant qualities, the material is advised for use in ASME pressure vessels in working service over 525 °C.

The sizes of the fasteners range from M2 to M30. International standards like DIN, ASTM, and ASME are used to regulate sizes. Materials range in length from 3mm to 200mm, and their diameters range from M5 to M56, or 14 inches to 1 inch. Carbon, silicon, nickel, chromium, phosphorus, manganese, and sulfur are all components of UNS S30409 Studs. The fasteners’ minimum yield and tensile strengths are 205 MPa and 515 MPa, respectively, thanks to this material composition.

What Makes 304 & 304H Different From One Another?

The carbon content of Type 304/304H is regulated between 0.04 and 0.10 for enhanced strength at temperatures exceeding about 800 degrees Fahrenheit. Compared to Type 304L, Type 304H has a higher carbon content, which makes the steel more appropriate for use in applications requiring higher temperatures.

What Kind Of Stainless Steel Are Fasteners Made Of?

The 18-8 (300 series) and 400 series are the two most often used varieties of stainless steel fasteners. The 18-8 series has the best corrosion resistance and ductility out of the two. One of the most misunderstood stainless families is that of types 302, 304, 305, and 316.
