About the properties of 904L stainless steel bolts

904L stainless steel bolts, due to their high nickel, chromium, and molybdenum contents, offer excellent corrosion resistance, particularly in acidic, high-chloride, and seawater environments. They are also high-strength, with a minimum yield strength of 220 MPa and a tensile strength of 490 MPa. Their low carbon content also provides excellent resistance to weld-induced intergranular corrosion. Key applications include the chemical, oil and gas, marine, and food processing industries.

What's so special about 904L steel?

904L is more corrosion-resistant than other types of stainless steel. This metal offers exceptional resistance to pitting and crevice corrosion, making it ideal for use in harsh environments. While 904L is more expensive than other types of stainless steel, its superior corrosion resistance is well worth the price.
