Application and Benefits of Stainless Steel Fasteners

Because of its stability, strength, anti-corrosive, and high heat properties, stainless steel is one of the most commonly used materials for fasteners. The combination of steel’s strength and its superior anti-corrosion and heat-resistance properties results in a versatile, cost-effective alloy. Stainless steel is classified into three types: austenitic (300 series), martensitic, and duplex. Stainless steel has several advantages that make it unique as well as long-lasting. While stainless steel is the general term for corrosion-resistant steel alloys, small variations in the alloy’s constituents can drastically change the component’s electrical and mechanical properties. To name a few, the core of a stainless steel alloy can be chromium, nickel, copper, tungsten, or molybdenum.

Stainless steel fasteners are made from an alloy of steel that contains at least 10.5 percent chromium and is also known as Inox steel. Stainless steel fasteners and stainless bolts are available in over 150 different grades and surface finishes. Fasteners are typically unaffected by weak bases, but their resistance to acid attack varies by grade and is dependent on variables such as acid type, concentration, and temperature. 

Uses of Stainless Steel Fasteners:

  • Components that are exposed to saltwater, chemicals, or other corrosive environments.
  • High wear parts.
  • Sanitary equipment.
  • Components that are exposed to high heat and high stress.
  • Components that require superior strength and stability. 

Benefits of Stainless Steel Fasteners include:

  1. Stainless Steel is corrosion resistant

The fact that stainless steel is corrosion-resistant is probably its most appealing feature. Stainless steel contains slightly more than 10% chromium, which allows for the formation of a thin layer of chromium oxide on the material’s outer surface. This effectively prevents any corrosion or degradation from occurring as a result of oxidation or other corrosion-causing chemical reactions. Stainless steel is also resistant to internal and external hydrogen embrittlement, making it the most popular material for fastener manufacturing.

  1. Stainless Steel Fasteners are capable of self-repairing

The thin chromium oxide film on the fastener’s outer layer uses oxidation to combat oxidation. Isn’t that clever? The oxide layer not only protects the fastener from corrosion but also allows the fastener to self-repair. If the fastener is damaged by a scrape, dent, or other physical distortion, the bare alloy on the damaged part is exposed to oxygen. Oxidation causes another layer of chromium oxide to form on this exposed layer, protecting it from further corrosion.

  1. Stainless steel Fasteners have a long life

SS 904L fasteners can be used in extreme temperatures as well as underwater because the material is extremely durable. No other material can provide such long-term benefits, at least not unless you spend a fortune on it! While stainless steel fasteners may be more expensive at first, they are more cost-effective in the long run. You will save more money over time because stainless steel fasteners only need to be replaced every few decades.

  1. Stainless Steel Fasteners looks better

The visual appeal of stainless steel in any structure is undeniable. Its rugged yet sleek appearance has even prompted builders, manufacturers, and automobile manufacturers to allow the fasteners to show where they are used! When comparing the aesthetics of equipment built with stainless steel fasteners to that of equipment built with fasteners made of other materials, you will notice that the components built with stainless steel fasteners are much better to look at due to their anti-corrosion properties.
