The content visualized will be a rough layout enriched by material flow and process information.
For instance, new materials could lead to improved cutting and bonding technology.
Figure 2: Illustration of the proposed systematic Since the interrelations between different production levels need to be considered, on every level of the production system the impact with its respective scenarios can be visualized in different degrees of abstraction (e.g. material flow simulation, process simulation, layout planning).

The material is protected with a passive film.
However, generally high strength materials have susceptibility of high stress corrosion cracking (SCC) including sulfur stress cracking.
The difference of the plastic elongation of 15Cr and 13Cr SS is based on material strength.

The blast furnace slag could be used for the cement raw material, the roadbed material, the mineral admixture and the aggregate for concrete, etc.
From the above, the blast furnace slag fine aggregate is good material that could replace the natural river sand as fine aggregate in concrete

Introduction Thermal mass is defined as the ability of a material to store (charge) heat, and later on release (discharge) it when activated mechanically or naturally through one or a combination of conduction, convection and radiation [1][2].
The most important parameters affecting the performance of thermal mass are material thermal properties, location of thermal mass, ventilation rate and external or internal gains too [3].
