A stainless steel 904L fasteners or Alloy 904l (N08904) is an austenitic steel, made up of an alloy of Iron, Nickel, Chromium and Molybdenum.In other words, it is a member of the alloy steel family, possessing the range of 10-30 percent of Chromium.
Two major properties that it delivers is: high resistance to corrosion and tolerate high temperatures.Adding to this, it is also cost effective.
Any available fasteners, whether fastener stainless 904L steel or any other fasteners have almost the same installation procedure.904L screws are used in this case to install into pre-drilled holes.Following are the steps to install a fastener, in this case, 904L fasteners:
There are many forms of bolts available, all follow the same procedures when it comes to installing them.904L stainless steel hex head bolts are very ideal and easy to use, without causing any damage.

When characterizing a 904L stainless steel bolts, it is stronger than ordinary 304 grade material.Standards: These bolts must meet the standards as per ASTM F593/ ASME SF593.This standard describes about the mechanical and chemical prerequisites for hex screws, bolts and studs.The diameter for these materials are 1/4''-1/2''.

Due to high corrosion resistance, ASME SF593 904L stainless screws are mainly used in seawater applications.It is very resistive when dealing with crevice pitting corrosion attacks.As a result, we use these screws in sea water, manufacturing ships and in food processing industries.
Added advantage is that the minimum tensile strength is 490 MPa meaning that it would require more than 490 MPa of force before actually breaking the fastener made of a 904L material.
There are some bolts of 904L bolts nuts which are much more expensive than other types of bolts as they contain high amounts of expensive ingredients, such as Molybdenum and Nickel.
On the other hand, it provides high corrosion resistance and ability to withstand high temperatures, is non-magnetic, and has good resistance to sulphuric, phosphoric and acetic acids, which other bolts do not have.
If looking for a condition of long-term durability, one time investment on 904L bolts is needed.Hence these are some of the reasons why it is most expensive than other bolts, but offer unique characteristics.
Availability of a SS 904L hex bolts depends on the availability and order size.If the supplier of the product stays nearby, or within your vicinity, you would get the product sooner and quicker.But this needs to be taken care of that order size matters as it might take some time to release them as compared to the lighter or smaller ones.
Adding to this, response time of the supplier plays an important role in this case.If the product order placed has location which is very far, it would take maximum days to reach your location.This would include shipping and then courier services.
