304 Stainless Steel Bolt

What is 304 Stainless Steel Bolt

Due to their strength, durability and attractive appearance, stainless steel fasteners are commonly used in different projects. In particular, 304, 304L and 304H are popular grades suitable for fasteners. Let us delve into the special features of these individual grades.

Grade 304:
The most widely utilized austenitic stainless steel is Grade 304, known as “18-8” because it comprises 18% chromium and 8% nickel. This combination results in great resistance to corrosion and sturdiness. These fasteners are sound for various applications and suitable for primary installation purposes in several industries.

Grade 304 stainless steel fasteners possess remarkable mechanical attributes. They feature excellent tensile strength, minimum yield strength of 205 MPa (30 ksi) and a minimum tensile strength of 515 MPa (75 ksi). Additionally, Grade 304 fasteners show exceptional resilience. They can withstand intergranular corrosion, making them suitable for all environments where a certain amount of acidity, alkalinity, or presence of chloride ions is expected.

Grade 304L:
Grade 304L stainless steel is a variation of Grade 304 with a reduced carbon content of 0.03%, indicated by the “L” for “low carbon.” This decreased carbon amount makes welding easier for these fasteners and lowers the potential for intergranular corrosion. As such, Grade 304L fasteners are commonly used in welding projects.

The characteristics of Grade 304L fasteners are comparable to those of Grade 304, offering great rust protection, strong tensile strength, and longevity. They offer great protection against corrosive atmospheres, including chemicals, coastal areas, and kitchens. Grade 304L steel fasteners are regularly used in construction, architecture, and marine engineering.

Grade 304H:
Grade 304H stainless steel is a variation of Grade 304, having a higher carbon content. The letter “H” indicates the increased carbon content lies between 0.04% and 0.10%. These increased carbon levels ensure greater resistance to higher temperatures, so they are suitable for applications that require contact with high heat.

Grade 304H fasteners have almost the same level of protection against corrosion as Grades 304 and 304L. Moreover, due to their high carbon content, they are not susceptible to sensitization and intergranular corrosion if they stay at temperatures between 800°C and 1500°C (1472°F and 2732°F) for an extended period. They are regularly used for heat exchangers, boilers, and pressure vessels.

At Sumit Impex, we pay special attention to the packaging of our 304/304L/304H stainless steel fasteners. Each grade is carefully wrapped and put in strong boxes or crates to ensure they stay safe throughout shipping. We use top-notch packaging materials to ensure the fasteners arrive to our customers in perfect condition and prevent rusting or other damage.
