Manufacturing method
DIN 17175 10CrMo910 Seamless Steel Tubes may be produced by hot rolling, cold rolling, hot pressing, hot drawing or cold drawing.
The tube steel can be smelted in a flat furnace or an electric furnace according to the oxygen blowing method, and all steels should be cast in a static manner.
The 17175 10CrMo910 Seamless Steel Tubes Will be delivered through a suitable heat treatment. heat treatment includes:
– Normalizing
– Annealing
– Tempering; from the quenching temperature, it is not cold, but then tempered
– Adjust the mass by the isothermal transformation method.

Original material test
A thin sheet should be taken at the top end of each round or square bar ingot for a pickling test to determine if the top end is adequately cut. Ultrasonic testing can also be performed on the shrinkage hole as selected by the supplier.
Test:
Chemical composition verification test
hydrostatictest
Tensile test
Notched impact test
Yield strength test
Ring test
Nondestructive testing
Tube flag
All steel pipes submitted for testing and acceptance shall be marked on the left and right sides of the pipe end at 300 mm. The mark is usually a number. Thin-walled tubes can also be used in other forms.
