SUPRAFORM TM 380
High-strength low-alloy (H.S.L.A.) steels have been commercially available for some time now.  However, they have suffered form the disadvantage that they are generally available in thicker sections, need special precautions when being welded and, because of their high strength, are more difficult to form.
SUPRAFORM TM 380 is a steel which overcomes the above limitations.

TM 380 is a H.S.L.A. steel, has a minimum yield strength of 380 MPa and, because of the low carbon content, typically 0.06%, has excellent weldability when using any of the standard arc or resistance processes, without the need to take any special precautions.  Severe forming can readily be carried out on TM 380 due to its superior formability, thus further increasing the steel's versatility.
With the need for higher yet stronger structures, effective mass savings can be achieved without the penalty of reduced overall strength by selecting a steel which has a combination of higher tensile and yield strengths and reduced thickness.

Typical applications for TM 380 are body and chassis components for tipper trucks, bumper brackets, engine mounting brackets, crane jibs and booms, trailers, mining equipment, rolling stock, cold formed sections, etc.
