From time to time, galvanisers get inquiries about galvanising special steels or unusual steel sections that are outside the normal range of steels processed on a day to day basis through the company's galvanising operations. While these steels can present problems for galvanising, it is sometimes possible to accommodate these ...

For some materials and material combinations the use of fusion welding is not practicable. Intermetallics may be formed at the joint interface or cracking may occur at or near the interface, which restricts the use of the joint in any service application where significant loading has to be withstood. However, ...

Steels are usually defined as alloys of iron and carbon, containing not more than 2% carbon, with or without other alloying elements. With more than 2% carbon, the material comes into the category of ‘cast iron’.
Carbon steels
Steels containing only carbon as the specific alloying element are know as carbon steels. ...

Aluminium alloy 6082 is a medium strength alloy with excellent corrosion resistance. It has the highest strength of the 6000 series alloys. Alloy 6082 is known as a structural alloy. In plate form, 6082 is the alloy most commonly used for machining. As a relatively new alloy, the higher strength ...

Metallurg Aluminium’s briquette-form alloying products are used in casthouses and foundries for accurate compositional adjustments of alloy melts or for bulk element addition. The distinctive shape of these products is created as the product's components are compressed between pillow-shaped indentations on two opposing rollers. This shape promotes ease of transport, ...

In the past when architects and designers mentioned concrete, people rarely got excited. It usually meant a dull, grey, visually unappealing appearance. Today though, thanks to new technological advances, concrete can be cast in a variety of finishes and colours offering architects and the construction industry a material that is ...

atteries and fuel cells are electrochemical cells used to generate an external electrical current. They consist of an anode, where oxidation occurs, a cathode, where reduction occurs, and an electrolyte through which ions can travel between electrodes (see Figure 1 for a schematic of a common battery cell). In fuel ...

The original austenitic manganese steel, containing about 1.2% C and 12% Mn, was invented by Sir Robert Hadfield in 1882. Hadfield`s steel was unique in that it combined high toughness and ductility with high work-hardening capacity and, usually, good resistance to wear.
Consequently, it rapidly gained acceptance as ...

Manganese
All commercial steels contain 0,3-0,8% manganese, to reduce oxides and to counteract the harmful influence of iron sulfide. Any manganese in excess of ...
