If you are looking for fasteners that will stand up to industrial abuse, you might want to consider Stainless Steel B8 fasteners. These fasteners are made from 304 stainless steel (UNS S30400) and are widely used in several industrial systems. In addition, they are highly corrosion-resistant. Read on to learn more about B8 fasteners and how they work. 


These fasteners are used to attach studs, nuts, and bolts to a variety of materials. B8 fasteners are made to meet the ASTM A193 Standard for corrosion-resistant austenitic stainless steel. These bolts are designed to withstand high temperatures and pressure. 


The standard also lists the mechanical properties, hardness requirement, and preferred heat treatment for these fasteners. The specifications also provide information on product marking, tensile strength, and size. Tensile strength of 3,000 pounds is the maximum recommended for a fastener.


The most common stainless steel grade for fasteners is Type 304. This type of steel undergoes carbide solution treatment (also known as solution annealing) and is used for moderate to high-temperature applications. For example, Class 2 B8 nut is strain-hardened to reduce galling. The bolt is also marked with "B8M" for Strain-Hardening.


As an industry-standard, ASTM A193 specifies the size and thread for stainless steel fasteners. As a result, B8 and B8M fasteners are both manufactured in Mumbai. You can find ASTM A193 SS B8 fasteners in Mumbai and many other places around the country. So if you're looking for fasteners for industrial applications, you should make sure to find the one that meets the specifications for your application.
