Rust and Stainless Steel Fasteners

Stainless steel is so named because it is corrosion resistant; it is a term used to define steels that are very resistant to tarnishing and rusting. In stainless steel, there is a high percentage of chromium that helps form a thin chromium oxide layer that prevents corrosion.

Many people use stainless steel because of its resistance to corroding elements. Even if the surface of your project is damaged, the chromium will react with oxygen to create a new protective layer that resists rust and corrosion.

Can stainless steel rust? While for the most part stainless steel resists rust and corrosion, if the stainless steel is not sufficiently alloyed for the environment, it cannot maintain the thin layer that helps prevent corrosion. However, stainless steel is more resistant to rust and other corrosive materials than many metals. If chosen probably your stainless steel fastening solutions should last you a long time and they should fight off corrosion.

If you are looking to replace your current fasteners or you are curious about whether stainless steel would be a good choice in your next project, contact us at ProvenProductivity@bossard.com. We are happy to help answer your questions and find you a fastening solution that works well with your current project.

A Closer Look at Stainless Steel

Fastener Materials: A Closer Look at Stainless Steel

Should I use Stainless Steel for fastening in my next project? That’s a good question. Fasteners come in a variety of materials and it is important to consider your project before you decide what material to use for it.

Many fastening options involve steel. The main options you have for steel are Low Carbon Steel, Medium Carbon Steel, Alloy Steel, Stainless Steel, or Austenitic Stainless Steel. Let’s take a closer look at Stainless Steel.

Stainless Steel
Stainless steel is made up of alloy steels that contain a minimum of 10.5% chromium content. The presence of chromium creates an invisible surface film that resists oxidation and makes the metal corrosion resistant. If the surface is damaged, it rebuilds itself in the presence of oxygen. It is important to understand the self-healing process because stainless steel used in a low oxygen surrounding is susceptible to aggressive influences if the protective surface layer becomes damaged.

Stainless steel is divided into three classes: Austenitic, Martensitic and Ferritic.

Stainless Steel fasteners are a good option when you need a fastener with high corrosion resistance because these fasteners will not easily deteriorate. If you have questions about Stainless Steel fasteners or need help in deciding on a fastener, contact us at ProvenProductivity@bossard.com. Our experts can help you get the materials you need for a successful project.

A Closer Look at Alloy Steel

alloy steel for fasteners

Fastener Materials: A Closer Look at Alloy Steel

There are a lot of fastener options out there. When picking the fastener for your next project, you are going to want to consider the material it is made of. Many of our options include steel fasteners. The main options you have for steel are Low Carbon Steel, Medium Carbon Steel, Alloy Steel, Stainless Steel, or Austenitic Stainless Steel.

Carbon Steel
Low Carbon Steel, Medium Carbon Steel and Alloy Steel are all types of Carbon Steel. They are separated into these three groups because the mechanical properties of these fasteners are based on the amount of carbon in the fastener.

The vast majority of fasteners that are manufactured use carbon steel. This is because it is inexpensive, but also because it has a broad range of strength capabilities. Let’s take a closer look at one type of Carbon Steel: Alloy Steel.

Alloy Steel
Alloy steel is carbon steel that contains additives such as boron, manganese, chromium, silicon, etc. Additions of these elements improve the capacity of alloys to be heat treated to a wide range of strength and ductility combinations. However, the higher the strength the great the risk of hydrogen embrittlement if plated.

Alloy steels have a tensile strength in excess of 150,000 psi (1034 MPa).

SAE Grade 8 (metric class 10.9, 12.9) fasteners are made from alloy steel with AISI grades 4137, 4140, 4340, and 5140 falling into this category.

Benefits of ecosyn®-plast Screws

ecosyn®-plast Screws

There are many factors to consider when determining what kind of fastener you want to use in a project. Recently, there has been a desire to make products lighter, and the type of fastener can play a key role in the weight of a product. That is one of the reasons why ecosyn®-plast is a good fastening option.

You may think that ecosyn®-plast is only used for thermoplastics, but that does not necessarily have to be the case. ecosyn®-plast screws were created through the experience in thermoplastic screwing, but they have many advantages for applications outside of thermoplastic screwing as well.

Check out some of the benefits of ecosyn®-plast fasteners:

  • High durability of screw joints under various conditions in different thermoplastic applications
  • Optimized thread geometry for low stress generation in joints
  • Self-locking, no additional locking elements are needed
  • High generation of preload
  • High breaking torque and tensile strength of screw
  • High safety during assembly secured via low installation torque and high stripping torque
  • Minimized loss of preload secured via enlarged area of contact surface under head

When working with thermoplastic elements, or when looking for a fastener of a lighter weight, the advantages of using ecosyn®-plast screws are clear.
