CrMo steel composite plate
Thread Content
Is there any stainless steel composite sheet with a base layer of CrMo steel? Why is it so rare to see? The commonly used base materials are Q345R, Q245R, and so on
Yes, 15CrMo+0Cr13 is a composite plate of chromium-molybdenum steel.
The properties of CrMo steel and stainless steel are similar, as are their costs; there is no need to create composite sheets anymore
Reply to 4#: As long as it’s comfortable is enough. It’s not a matter of cost; he’s considering the strength and corrosion resistance requirements of the materials
Composite plates with a Cr-Mo steel substrate are very common. I have supplied substrates for companies that produce such composite plates; the required Cr-Mo steels include SA387, 14Cr1MoR, 15CrMoR, etc., and the quantities needed are quite large. Yuugang Panglong: 13137747779
Is the temperature factor taken into account when using CrMo steel at the grassroots level?
Yes, our company produced three types of containers this year: hydrogenation reaction towers made of 15CrMoR and stainless steel, with a thickness of 34 mm. It was difficult to create the grooves for these components; they had to be machined, and the grooves were of the single-bevel type. However, if larger nozzles have non-radial openings, it becomes very difficult to create grooves for them (and these nozzles are quite thick reinforcement pipes); therefore, in the design phase, large nozzles should preferably not be designed in a non-radial format.
Reply to 7# jia717: On the one hand, it is due to the good high-temperature strength and creep resistance of Cr-Mo steel. On the other hand, high-temperature hydrogen-facing equipment requires good resistance to high-temperature hydrogen corrosion, and Cr-Mo steel is suitable for this purpose
