The grade 30CrMo steel pipe has high strength and toughness, high hardenability and critical quenching diameter of 15~70mm in oil. The thermal strength of grade 30CrMo steel pipe is also good. It has high temperature strength under 500, but its strength decreases significantly at 550. Welding of alloy elements is quite good at the lower limit, but the welding property is medium at the upper limit, and it needs to preheat to over 175 before welding. The grade 30CrMo steel pipe has good machinability and medium plasticity in cold deformation. The first type of temper brittleness is found in the range of 300~350 during heat treatment. The grade 30CrMo steel pipe has a tendency to form white dots.

Please contact us freely if you have any need in the grade 30CrMo steel pipe. Katalor can supply the high quality grade 30CrMo steel pipe with your requirements. We can send the details and the quote about the grade 30CrMo steel pipe to you.
