DIN 2393 St 52.3 steel tubes manufacturer in India


Grade St 44-2 is a low carbon alloy steel, whose primary use is for structural purposes. Generally, this alloy is used in conjunction with standard DIN 2393 to form different types of seamless and welded tubes. Industries such as the automotive as well as mechanical engineering use the DIN 2393 Welded Precision Steel Tubes in several applications. Precision tubes have a tighter tolerance and when used for any application, they are intended to have a snug fit. Hence, the use of these tubes improves the functionality of the application. Moreover, the tight tolerance is why the rate of mishaps are low when industries use the DIN 2393 St 44-2 Precision welded steel tubes.

In addition to mechanical engineering and automotive industry, these tubes have a special place in industries such as Electric industry, Hydraulic system steel tube, Gas spring, Construction machinery as well as in Heat exchanger and Condensers. The low cost of DIN 2393 Grade St 44-2 is another attractive feature of these tubes. It is easier to customize these components by use of several surface treatments. Most carbon tubes lack the corrosion resistance properties of their alloy steel and stainless steel counterparts. This is a feature that can be added by the use of treatments like galvanization or coating with zinc or anti-corrosive oil or even varnishing. Other value added finishes that are commonly used on the DIN 2393-2 Grade St 44-2 bright drawn Tubes include polishing or brightening or even painting with metallic colours.
