In January 2015, the Coatinc Company Holding (TCC) assumed a 49 percent share of a US corporation headquartered in San Diego, California. In the future, this corporation will operate galvanizing facilities that are currently being built in Tijuana in the Mexican state Baja California. The galvanizing plant will be launched under the name “Galvanizadora California.” An American corporation by the name of “California Galvanizing and Steel Structures” will undertake the sales.

For the last 18 months the European Powder Metallurgy Association (EPMA) has been working on the development of a revised PM Roadmap called 'Vision 2025'. The purpose of the Vision 2025 booklet is to be a tool to aid in the promotion of the PM industry to government, third parties and end users. It is also envisaged that the information contained in the booklet will provide some useful insight into key trends and development areas for the different sectors of the European powder metal industry.

Factorial design was used to investigate the contribution effect of cooling rate of stage between rolling and coiling and cooling rate after coiling on grain size, pearlite lamellar spacing, mechanical properties and hardness of hot rolled narrow 65Mn strip. The contribution of both cooling rates before and after coiling process, and the interaction combination effect of both rates were determined for each measured property. The regression models were built up to identify grain size, pearlite lamellar spacing, mechanical properties and hardness as a function in cooling rates before and after coiling process.
It was found that the contribution effect of cooling rate before coiling on grain size growth, enlargement of pearlite lamellar spacing, Ultimate Tensile Strength (UTS) and elongation is negative with different magnitude and it has positive effect on Yield Strength (YS) and hardness. Cooling rate after coiling has negative effect on grain size growth, enlargement of pealite lamellar spacing and elongation while it has positive contribution on UTS, YS, and hardness. The interaction combination effect of both two rates has very small positive contribution on YS and elongation, it has small positive effect on grain size growth, enlargement pearlite lamellar spacing, and it has large negative contribution on UTS and hardness. Factorial design technique is a successful technique to analysis the effecting parameters.
