    Alloy Steel Castings And Its Surroundings


    It makes Alloy Steel Castings of various grades as per the client’s requirement. Also We have developed their own method study cards. We produce the alloy steel castings weighing from 0.5 kg to 200 kg. of different materials like SS 304, SS 316, SS 316L, Carbon Steel products, that they make, are Couplings, Brake Drums, Rings, Hub, Bearing Housing, Excel Box, etc. Most of these products are prone to have defects due to porosity. It has been understood that Porosity plays an important role in castings. As casting involves gases, there are chances of defects due to porosity increases.

    Porosity seems to be a bigger problem when the humidity in surrounding environment (like one in monsoon) is more, or when metal is poured at very high temperature. It accounts almost 60 to 70 % defects in monsoon season. Not only in monsoon, but even in normal environment with such unfavourable conditions, it creates trouble for casters. So, it is great to work on porosity to obtain such favourable conditions in order to get defects free castings.

    However, one should also understand that one can never get rid of gases completely as different gases involve through various ways during casting . One can only get the optimum favourable conditions in order to reduce porosity. But of course, efforts has to be made for analysing the causes of porosity and also for reducing porosity in castings to bring the defect ratio as low as possible , which in turn decreases defect costs and increases Profit of company. Thus, in longer run of company, this analysis may be helpful in quality improvement.
