You're changing the crystal structure of the actual stainless itself and I'm going to demonstrate that to you right now. Zinc plated alloy steel is most often available in Grade A, Grade C, Grade 2, Grade 5 and Grade 8. I'm going to show you that this is magnetic. The length of the 1.4301 304 Stainless Steel Threaded Rod ranges from M02 to M33 in the metric system. They have a tensile strength of between 180,000 and 250,000 PSI. It is also harden-able by cold working. Let's get started. Please feel free to contact us for more information and the pricing of these fasteners.
This is very common in those applications. Its corrosion resistance is greater than 18-8 stainless, which is why we recommend using 316 stainless steel fasteners for salt-water application. Really the only one that's non-magnetic, other than some special stainless, is this 316 stainless and that's the stainless you use in salt-water applications and that's the one that you won't find surface corrosion or deep corrosion. The information from this chart is derived from the MCA technical document, "Fastener Compatibility with Profiled Metal Roof and Wall Panels". These are ideally used with Thru-Bolting applications whereby bolts, machine screws, sockets, U-bolts and threaded rods are required. Hex tap bolts are used in drilled and tapped holes which are threaded full length. 3 mm
This is a stainless bolt. They are often used in marine applications in freshwater environments but will not work as effectively in a salt-water environment as 316 stainless. c ) 316 Stainless Steel:
Due to the 304 Stainless Steel Nuts being good at resisting these contaminants or corrodents, they have a long work or service life. Below are some of the many bolt grades of stainless steel that we carry. Socket products: These are excellent for use where corrosion resistance is required or where you have limited space. What you're buying. This increased amount of carbon gives the 400 series of stainless steels increased strength characteristics as well as better performance at elevated temperatures while still maintaining some corrosive resistance.
