Construction and Architecture. Why Use Stainless Steel?
To prevent forms of corrosion such as pitting and crevice corrosion, in construction and architecture it is very important to choose the right stainless steel. Stainless steel and corrosion resistance The common characteristic of all types of stainless steel (austenitic, ferritic, martensitic and austenitic-ferritic) is the resistance to corrosion. How can they be immune from […]
Austenitic Stainless Steel Fasteners. Why Use Them? PART II
Here is the second part of our post on austenitic steel connection elements. What are the advantage of using them? Temperature resistance Austenitic steel has good resistance to temperature. For connection parts galvanized the Chromating is destroyed at temperatures above 80°C. So drastically reduce the corrosion resistance. Maintenance Austenitic steel screws and nuts are raw. […]
Austenitic Stainless Steel Fasteners. Why Use Them? PART I
Today we are talking about what technical topics for the use of austenitic steel fasteners. Also the avoidance of potential problems. Here are some advantages The surface of austenitic steels is shiny and of good appereance. In fact, a connecting element that does not rust will donate aesthetic perfection. In addition to aesthetics, austenitic steels […]
Safety Washers and Tab Washers â What They Are For?
Stainless steel safety washers are thin plates (typically disk-shaped) with a hole (typically in the middle). Washers. Where to place them? Washers are normally used to distribute the load of a threaded fasteners, such as a screw or nut. A locking washer that works by having a side tab that can be bent into place […]
Chemical Composition of Austenitic Steel
Austenitic Steel. More of all fasteners (97%) made from stainless steel are produced from this steel composition group. Why this choice? This group of steels is characterised by impressive corrosion resistance and excellent mechanical properties. The classification of austenitic steel This type of steel are divided into 5 main groups whose chemical compositions are as […]
Characteristics of Fasteners Mechanical Properties at High Temperatures?
Fasteners mechanical properties. What is the influence of elevated temperatures on mechanical properties of fasteners? What is the effects? The fasteners mechanical properties and its functional performance could be affected to the elevated temperatures. Service temperatures: What can we check with the encreasing temperatures? May occur respectively: – lower […]
How Do You Calculate the Screw Pull-Out Stength?
Do you want to know about steel screw pull-out strength? Weâll help you to understand how to do it. How do you calculate it? The screw pull-out strength is calculated in accordance with section 8.7.2 of Eurocode 5 â Design of timber structures (version UNI EN 1995-1:2009). What is the result? The value that you […]
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. […]
