Free Cutting Brass Rod

We are one of the pioneer exporting houses and supplier of Brass Sheets Plates, which are all prone to sigma phase formation if exposed for long periods to a temperature of about 590 Degree C to 870 Degree C. The problem of grain boundary carbide precipitation in Brass Plates was discussed under inter – granular corrosion. The formation of sigma phase in Brass Plates is dependent on both time and temperature and is different for each type of steel. In general, Brass Coils is practically immune to sigma phase formation, but not so those grades with higher chromium contents with molybdenum or with higher silicon contents. Sigma phase embrittlement refers to the formation of a precipitate in the micro structure of Brass Slatting Coils over a long period of time within this particular temperature range.
