Amigo Impex is a renowned name in supplying and manufacturing of stainless steel 321 Fasteners. We have been part of this industry for many years serving our clients with our superior quality products. We specialize in these fasteners in all standard sizes.
These fasteners are made from common and widely used austenitic steel alloy as the name suggests. These fasteners contain a content of titanium in it. The presence of Titanium significantly increases the carbon content in the alloy. These results in a reduction in precipitation of carbide while the welding process. It is known for delivering tremendous resistance to oxidation due to the effect of air, water or chemicals. Its mechanical property of extremely high resistance to all types of corrosion makes it suitable for many process-oriented industrial applications. These fasteners come with a workable creep length. These are extremely convenient for forming and drowning applications.
The most important feature of the fasteners is that these are resistant to most of the organic and inorganic chemicals. These fasteners exhibit a higher-order resistance to the effect of nitric and sulfur acids. To go with that these fasteners offer resistance to all kinds of corrosion. This it does by tying up the carbon and nitrogen as carbides or nitrides. These fasteners are prone to pitting and crevice corrosion if in case it comes in direct contact with warm chloride environments. So this is something one has to take care of. This is because of the marginal content of chromium in it.
Stainless steel 321 fasteners are of great use in high-temperature environments. The temperature can go up to elevate levels while industrial applications and even in such situations as well these fasteners are reliable and sturdy. This is why these are always in high demand. These fasteners exhibit tremendous welding characteristics. These are used in several industries and industrial processes that is why these are quite popular. Some of the most prominent users of this category of fasteners are manufacturers of oil refinery equipment & industrial boilers. These are also used in the manufacturing units of chemical and pharmaceutical equipment. These fasteners are not recommended for exposure to saltwater. Therefore these are not to be used in marine applications.
