This low alloy grade has significant additions of molybdenum and manganese to it. Besides its use in boiler systems, the 15Mo3 Pipe is useful for applications in the oil, gas and chemical industry. Generally, these industries make use of heat exchangers, as a means of transference of heat among two or more solutions. Heat exchangers are applied in processes involved in both cooling and heating. Since the low alloyed 15Mo3 is an alloy which can be used in elevated temperature setting, it is considered to be ideal as Din17175 Seamless Steel Pipe for Heat Exchangers.  In many instances, businesses in these key sectors lookout for the best and safest option for their applications. The use of DIN 17175 15Mo3 Seamless Pipes here would be advantageous as they have the ability to withstand almost 20% more stress than their welded counterparts.
