Hex Forge Inc. is a leading provider and manufacturer of martensitic Stainless Steel 904L Hex Nuts in various sizes and shapes. 904L stainless steel is an austenitic, non-stabilized grade. This type of stainless steel has a low carbon content, as indicated by the L next to the grade number. These stainless steel 904l self-lock nuts have a maximum carbon content of 0.02 percent. The low carbon concentration of these fasteners prevents intergranular corrosion by making them resistant to welding sensitization. This high alloyed stainless steel grade has copper in its alloy to improve its resistance to strong reducing acids such as sulphuric acid. The 904L Hex Nuts are also known for their exceptional formability, durability, and weldability. Because stainless steel 904l heavy hex nuts are non-magnetic, they can be employed in situations where their non-magnetic properties benefit the planned product. While fasteners made of Grade 904L stainless steels have considerable oxidation resistance, their structural stability is compromised at temperatures beyond 400°C. The alloy of 904L Stainless Steel Nuts can be solution treated between 1090 and 1175°C, after which the fastener can be quenched by rapid cooling. Stainless steel 904l flange nut must be cold worked before solution treatment to achieve the best stress corrosion cracking resistance. Despite this, grade 904L Nuts are still prone to stress-related cracking, particularly in chlorine conditions.
Epoxy coating, electropolishing, zinc plating, chrome, oxidation, and other finishes are available for the AISI 904L Hex Nut. The 904L Hex Nuts, like several other austenitic stainless sheets of steel, have a high oxidation resistance. However, because of the risk of structural failure above 400°C, using ss 904l Hex Nuts is not recommended at such temperatures.
