Advanced High Strength Steels and their Heat Treatment Jul 30, 2017 · (v) Hot Formed (HF) Steel - The use of HF boron steel, called ultra-high- strength steel (UHSS) by some automakers, has grown rapidly in Europe; other materials for hot forming are also being investigated, as well as new coatings to improve corrosion resistance. - HF steel is typically boron-based (0.002-0.005% B).
Alloy steels are workhorses of many industries because of their low cost, extensive availability, ease of processing, and mechanical properties. Alloy steel is a steel which has had small amounts of one or more elements (other than carbon) such as such as manganese, silicon, nickel, titanium, copper, chromium and aluminium in addition.
Blog Omega SteelLead (Pb) It is almost insoluble in liquid or solid steel. However, lead is sometimes added to carbon and alloy steels by means of mechanical dispersion during pouring to improve the machinability.

The Influence of Peritectic Reaction/Transformation on The work presented here examines the surface cracks that can form during the continuous casting of near peritectic steels due to the volume changes during the peritectic reaction/transformation. The investigated samples were collected during plant trials from two different steel grades. The role and mode of the peritectic reaction/transformation are found to depend on the composition of the
