The Quality of Stainless Steel Alloys in Your Refractory Anchors

May 2012

Manufacturing refractory anchors is not just being able to hammer out a product made with a certain composition. It should be taken into consideration what the intended use of that product is. SILICON is one of the few companies able to support and inform customers regarding the metallurgical preparations for each application.

It is crucial to know what type of material needs to be used and how this raw material needs to be fabricated. 310 is NOT always 310. It is not that simple; a lot of other parameters inherent to the core properties of the metal have to be taken into account in order to have a refractory anchor of the highest quality! Chemical composition is only one component of what makes an alloy type appropriate. Mechanical is another important feature. Depending on the hardness for instance, bending can occur properly or not.

What can you do to ensure your refractory anchors have a good alloy quality? You need a material certificate.

SILICON Refractory Anchors Always Use Prime Material 

What are Material Certificates?
Material Certificates are documents conforming to the ISO standard EN10204-3.1 which lists all the exact chemical properties of the alloy plus all the results from tests with all types of force applying equipment (pull strength, elasticity, etc.). If you cannot get it, it might be because of second-choice material.

"Good quality" refractory anchors are more than just the right size and shape, they have to have the right alloy. Don't be fooled by dirt cheap second-choice steel alloys.

Using Prime material for our refractory anchors has been one of SILICON's longest traditions and still is. For over 30 years SILICON has experienced it all and can give the best advice on these critical matters. We therefore recommend you use prime material over second-choice material alloys.

Correct estimation of what your installation needs is vital to your project, bad alloy quality can lead to early breakage and disasters and can cost thousands in repairs. We hope this information gives you a new insight into material alloys for your refractory anchors.
