Corrosion – Chapter 1. – Corrosion in Europe

Corrosion in Europe   EUROCORR [1] is the most important corrosion conference in Europe, which was organized for the first time in France. It has become an annual event, which rotated between different countries from Italy, Sweden, Austria, France, Czech Republic, Serbia and finally to Spain. EUROCORR 2020 will be held in Belgium, while Hungary

It’s all up with metals? Part 1.

The use of structural materials throughout history To understand better this, it is worth looking at the following figure, which illustrates the rate and importance of the use of structural materials throughout history. What kind of materials humanity used was highly dependent, among other things, on the availability, processability of raw materials, and the knowledge

Welding dissimilar metals 3.

Because of the cracking sensitivity of nickel alloys, heat input needs to be limited and interpass temperatures should not exceed 150 oC. In order to decrease dilution, welding straight rows is advised to avoid electrode oscillation. Until now, we’ve discussed dissimilar metal welds between unalloyed or low-alloyed materials and high-alloyed iron based materials. However in

Welding dissimilar metals 2.

The filler metals in the table are either purely austenitic or approximately 5-40% ferrite containing structures. General unalloyed steel, eg. S235 and 19/9 dissimilar metal welds welded with 309L filler metal consist of 92-95% austenite and 5-8% ferrite [1]. The weld’s high ductility can withstand heat contraction, and the low ferrite content ensures a high

Welding dissimilar metals 1.

First, the metallurgical properties of the two metals to be welded should be taken into account, as well as their differing chemical compositions which will determine the microstructure formed after the weld and thus the resulting joint’s physical properties. In addition to this, the welding parameters are also important, including heat input, the two metals’

Module Constructor for Chemical Industry, Germany

Thanks to EQUIMETALS we could quickly identify the specific materials and needs to acquire the proper technical information for an unexpected Finnish chemical industry assignment. Without it, we wouldn’t have been able to do so.

Metal Supplier, New Zealand

We were searching for a seamless metal tube on a very tight deadline and no trader could even make an offer to us. But luckily the EQUIMETALS database offered several alternatives for substitute metals! We made a deal with the designer, and subsequently got the job done on time.
