The analysis of the difference between the 15CrMo alloy steel pipe and the 1Cr5Mo alloy steel pipe by the alloy steel pipe plant The two figures at the beginning of the steel number indicate the carbon content of the steel, and is calculated by the number of thousandths of the steel. The content of the following elemental component is connected to the number, and the content is less. On the element symbol.
The first 15CrMo alloy steel pipe indicates that the carbon content is 1.5%, and the alloy contains chromium and molybdenum.
The second 1Cr5Mo alloy steel pipe represents an alloy containing 0.1-0.15% of carbon, 5% of chromium, and molybdenum.
The above is the difference between the components, alloy steel pipe plant and then simply introduce the difference between the performance of alloy steel pipe:
15CrMo steel pearlite heat-resistant steel, has a high thermal strength (δb ≥ 440MPa) and oxidation resistance at high temperatures, and has a certain degree of resistance to hydrogen corrosion. Due to the high content of Cr, C, and other alloying elements in the steel, the hardenability tendency of the steel is obvious and the weldability is poor.
1Cr5Mo alloy steel pipe Features:
Has good oxidation resistance, corrosion resistance and tissue stability. High thermal performance and good process performance.
application:
High temperature sulfur corrosion, high temperature hydrogen and hydrogen sulfide corrosion, organic acid corrosion.
Reheater tubes with a wall temperature of 630 °C to 650 °C.
