INTRODUCTION High strength steel as reinforcement for concrete has received some serious attention by researchers and by the construction industries as long ago as the early 1900' s. Recent developments abroad, notably in Sweden, Germany and Austria, have caused renewed interest in the use of this material in concrete structures. The term "high-strength" is somewhat ambiguous since it usually "Effect of Alloy Composition on Carburizing Performance of Jan 01, 2009 · This paper investigates the effect of alloy composition on the gas carburizing performance of AISI 1018, 4820, 5120, and 8620 steels. The mass-transfer coefficients and carbon diffusivities were calculated from experimental measurements using direct flux integration. Although steels with high concentration of austenite-stabilizing elements (Si, Ni) increased carbon diffusivity in austenite
For this reason, these steels are used for elements of structures such as mobile cr anes booms, vehicle frames, drilling platforms, pipelines, pressure vessels, bridges, etc. [1-2].

The structural steel in the form of a bar and reinforcing steel generally have the highest corrosion rate. This is possible linked to different manufacturing and treatment processes experienced by each of the structural steels. (a) (b) Figure 5.
A method for reforming hydrocarbons comprising coating portions of a reactor system with a material more resistant to carburization, reacting the material with metal sulfides existing in the portions of die reactor system prior to coating, fixating and removing at least a portion of the sulfur in the metal sulfides, and reforming hydrocarbons in the enactor system under conditions of low sulfur.
