Katalor as a famous steel supplier and exporter in China, so GB/T 5310 15CrMoG boiler pipe is our mainly product. Lots of GB/T 5310 15CrMoG boiler pipe user know its chemical composition and mechanical properties. For the effect of mainly elements in GB/T 5310 15CrMoG boiler pipe, maybe few people know that.
Katalor as the C, Mn and Mo for example to introduce the elemental effect:
C: pearlite or dispersed alloy carbide is formed in the GB/T 5310 15CrMoG boiler pipe to strengthen the steel. In the microalloyed steel, in order to form a certain amount of carbon-nitride, the carbon content needs only 0.01-0.02%; therefore, carbon reduction is an inevitable trend in the development of such steel, thereby greatly improving the toughness and welding performance of the GB/T 5310 15CrMoG boiler pipe.
Mn: high Mn/C ratio is beneficial for improving the yield strength and impact toughness of GB/T 5310 15CrMoG boiler pipe. Manganese can reduce the γ→α transformation temperature; it is beneficial to the nucleation of acicular ferrite; it can increase the solubility of carbon-nitride forming elements in γ-Fe during heating, thus increasing the carbide in ferrite. The amount of diffuse precipitation. In addition, the strength loss of the Bowinger effect can be offset by the change in the stress/strain characteristics of the GB/T 5310 15CrMoG boiler pipe due to high manganese.
Mo: Molybdenum GB/T 5310 15CrMoG boiler pipe (~0.15% Mo) has higher strength and higher toughness than traditional ferritic-pearlite steel. Molybdenum inhibits pearlite transformation during cooling. The amount of molybdenum contained in acicular ferritic steel and ultra-low carbon bainitic steel is generally 0.2 to 0.4%.
The quality of GB/T 5310 15CrMoG boiler pipe depend on the content of elements, so different content has different effect. So the effect of elements in GB/T 5310 15CrMoG boiler pipe is very important is very important. Katalor has professional team to produce GB/T 5310 15CrMoG boiler pipe with high quality. Pease contact us if you have any need in GB/T 5310 15CrMoG boiler pipe.
