High Alloy Steel Pipe Fittings Manufacturers In India, Refer Low AS Pipe Fittings Dimensions In Millimeter.


Alloy steel envelopes several grades of alloys including many high and low steel grades. Depending on the content of alloyants present in the material, the Alloy Steel Fittings could be classified as low alloy steel or high alloy steel. For instance, the content of alloyants in Low AS Pipe Fittings ranges to about 8%. Contrary to low alloy grades, high alloy steels contain more than 8% alloyants. A high alloy steel typically consists of chromium content amounting to about 10% of its total weight, with the remaining content being Iron. Hence, the degree of enhanced mechanical property is much higher in High Alloy Steel Pipe Fittings as compared to low alloy steels. As the content of alloying increase, the properties become more prominent. One such property is its resistance to oxidation. This is a feature that has been attributed to the presence of a high content of chromium in the alloy. Chromium forms a passivated oxide layer on the surface of the fittings, thereby proving to be an effective barrier to corrosion. Though, the cost of using a High alloy steel fitting is slightly higher in comparison to its low alloy counterparts.

What Is Alloy Steel Fittings?


Alloying elements for a chrome-moly steel include chromium and molybdenum in significant amounts. Which is why Chromoly Pipe Fittings derive their names from the addition of these two elements. One such chrome-moly steel is 41xx steel, which belongs to the SAE family of steel grades. In addition to exhibiting an excellent strength to weight ratio, these fittings are considerably stronger and harder as compared to the conventional 1020 steel. However, Chromium Alloy Steel Buttweld Fittings are not easily welded. Steels of this variety require thermal treatment both pre and post welding to avoid cold cracking.
