Which material standard applies to 45# steel forgings: NB/T47008-2017 or NB/T47010-2017? Could someone give some advice?

47008 refers to forged parts made of carbon steel and low-alloy steel, while 47010 refers to forged parts made of stainless steel and heat-resistant steel

This type of forged material is not used for pressure equipment

Aren’t NB/T47008-2017 and NB/T47010-2017 the standards for forgings used in pressure equipment? Why can’t they be used?

The question is: NB/T47010 is the standard for stainless steel forgings – is 45# steel included in it?

NB/T47008 is a standard for carbon steel forgings, but it applies to pressure-bearing equipment; is 45# material included in this standard?

With all this time, just take a look at the two standards and you’ll know, right? !
