Stainless Steel. Any of You Ever Hear of Thermal Conductivity?
It is common belief that the metals are conductors of heat. But not all metals are good conductors in the same way. The characteristic depends on the type of metal. The thermal conductivity of materials. What can we infer from the following table? The values of thermal conductivity of various metals. METALS Conductivity /W/(cm °C) […]
Dynamic Loads. The Resistance of Stainless Steel Screws.
Screws are notched components. Why are they considered as such? For their threading. And where the screws are subjected to repeated and irregular stress? In some cases the break occurs in the first load-bearing part of the thread, at the entry into the internal (female) thread. (in 90%) What is it necessary for the design? […]
Surface Pressure Under the Screw Head. How to Reduce It?
The allowable bearing pressure for a given material cannot be defined with absolute precision. Several factors play a key role in determining it: How Can Bearing Pressure Be Reduced? Bearing pressure can be reduced by adopting the following measures: Flange Bolts and Flange Nuts: What Are the Benefits? The main advantages include: Using flanged fasteners is generally a more effective solution than using large washers placed under standard bolts and nuts. […]
Stainless Steel. Chemical Stability.
Austenitic steels A1, A2 and A4 obtain their resistance to corrosion through a surface protective layer of oxide. When the surface protective layer is damaged If the surface protective layer is damage it uses atmospheric oxygen to regenerate itself. If access to atmospheric oxygen is blocked: Then even these steels will corrode. Some general […]
Not Only Tensile Strength..
After having addressed the issue of yield and tensile strength in one of our previous blog post. Secondly, there is the matter of elongation at fracture A, the tensile strength under wedge loading and head soundness. Elongation at fracture A [%] It is the permanent elongation measured on the fractured specimen related to the original measured […]
How to Prevent the Galvanic Corrosion?
Galvanic corrosion. When (for external application) we match stainless steel with other metals it is appropriate that they be separated by an non-metallic insulator. For example, including neoprene or nylon. Why do this? To avoid the risk of galvanic corrosion.
The Mechanical Joints. How to Fix Stainless Steel?
The Mechanical Joints. Stainless steel can be fixeded (or combined) with other materials through traditional techniques. Some examples are welding, brazing, bonding and mechanical joining. The latter will be the topic of this post. How to choose the best technique? Choosing the most appropriate method to use depends on many factors. Which ones? The mechanical […]
The Workability of Stainless Steel
The workability of stainless steel. Stainless steels be subjected to normal manufacturing processes. Some examples? The roll forming, bending etc.. Let us see them more specifically. Working processes As mentioned earlier today we talk about the workability of stainless steels. What are working processes? What are the differences? Austenitic steels are subject to work hardening. […]
Why Use Stainless Steel and Which One to Use?
Why use stainless steel? Stainless steel is a durable building material, thanks to its resistance to corrosion and low maintenance that requires. How to ensure these features? Make sure you use the appropriate qualities and surface finishes. How to choose the type of material? Corrosion resistance of stainless steel is given by chrome and it […]
The Electropolishing Process of Stainless Steel
The steel mill finishes are the basis of conditions of supply for all stainless steel plan products. In this post we talk about the process of electropolishing. What is the process of electropolishing? Electropolishing is an electrochemical process that can be used both for sheets and for components with complex shapes. What is it for? […]
