...carbon steel. The resistivity of material is best if it is less than 15 x 10-6 Ω cm. Materials of poor conductivity, such as stainless steels, can be formed by using a highly conductive driver, such as aluminium sheet, or a specially built high frequency machine. Different materials can be assembled together, such as metal rings on to plastic, glass, composites and...

...carbon steel, low-alloy high strength steel, and quenched and tempered low-alloy steel. Can also be used to weld stainless steel and aluminium alloys if required. The weld metal acquires the structure of a casting, wherein the sizes and orientations of the grains are governed by heat removal characteristics. Long columnar grains can be formed with microsegregation and...

...carbon mild steel (<0.2 wt% C) which is used to produce a wide range of components, mainly in the automotive and bicycle component industries. Mild steel has to be annealed before cold forging and at interstage processes. Cold forging causes strain hardening in the materials, resulting in increases of 30–120% in tensile strength and 100–300% in yield strength values....

...carbon steel, which can be hardened and tempered to give mechanical properties as good as, or better than, wrought alloy. Other steel compositions include steels suitable for carburising or through-hardening applications, e.g. Fe-1.8Ni-0.45Mo-0.2Mn-0.35C with a tensile strength of 930 MPa and elongation of 13%. Pre-alloyed aluminium alloy powders include the following...
