Choosing the best fasteners materials
Fasteners are available in a wide variety which includes the common steel to titanium, plastic, and other extensive options. With the best fasteners suppliers in Australia, other materials are coated or platings which increase the property of corrosion resistance or alter the fastener appearance. Fasteners material can be the best choice in brittleness, strength, corrosion resistance, galvanic corrosion features, and includes the cost. Fasteners manufacturer have an understanding of different materials. When replacing fasteners, it is generally best to match what you are replacing. In this article, we are going to mention the different types of materials that are the best for the project.
Different range of Fasteners
- Stainless Steel
Stainless steel is an alloy of low carbon steel and chromium for enhanced corrosion features. Stainless steel is the best in terms of price. Also, it contains anti-corrosive features which are best in terms of the metal, and if the material is scratched it will not be used during use or installation.
It is a common misconception that stainless steel is better as compared to regular steel. It is because of their low carbon content, many stainless steel alloys are not hard through heat treatment. It is important to take care of thee features:
- 18-8 Stainless
- Stainless 410
- Stainless 316
- Steel
Steel is the most common fastener material. Steel fasteners are a pain as various surface treatments such as zinc plating, chrome plating, and galvanization. Steel fasteners are commonly available in different grades:
- Grade 2
- Grade 5
- Grade 8
- Determining bolt grade
Bolts are marked ahead to show the type of grade bolt. The grade marking comes with different bolts and they have manufacturer’s marks.
- Grade 2
Grade 2 is the best choice for grade steel. This is the best choice for steel fasteners and you can even get in under your budget.
- Grade 5 or F
Grade 5 is hardened to increase strength and it comes with common bolts which are in different applications.
- Grade 8 or G
Grade 8 bolts get hard with Grade 5 bolts. This is the reason, it is strong and it is used for different applications. Also, the head has radial lines.
- Alloy steel
Alloy steel bolt is made with high strength which is heated. Also, these are not plated which gives them a dull black finish. The strength of this material is high and it is brittle at the same time.
- Silicone bronze
Silicone bronze is alloy and it contains tin & copper. Also, it is the best choice for marine environments. It is better over stainless steel, specifically in wooden boat construction and the re-fastening feature allows it to provide the features of corrosion resistance. If you are on a budget then this is not the best choice for you.
- Brass
Brass contains zinc & copper. It has the feature of corrosion resistance and is electrically conductive. Although, its use is limited to a certain extent because it is highly soft and the appearance is even better at the same time.
If you are confused about which option to go with, then get in touch with the fasteners suppliers to make the right choice.
