OCr13Ni4Mo trial martensitic stainless steel


Tensile specimens according to the same heat treatment system to deal with, such as the passage of the test results shown in Figure 13 2l and 21 and the ring from the table l3 visible,mulberry outlet, OCrI3Ni4Mo steel, low temperature impact values ??from 0C to a 60_a declined slightly, but with the declared temperature impact toughness degree rather than fundamental, Paul refers to two technical standards than 2 times, indicating the low-temperature impact toughness of steel well. Physical test No. 1 in 1992 children lettuce,uggs nederland,, drying shed the milk teeth back (back) wall of fire temperature ℃ Figure 10 back (case) temperature of the residual austenite fire I said,mulberry, nine temperature monitoring,ralph lauren danmark, C ring I1 magnetization of different heat treatment system strength of 19 pressure shell wrapped pension simulation results 6.9475 ℃ ■ Cut Ya-sensitive V-type tendency to test the impact of the sample by 1000 the first oil-cooling heat quenching 3O minutes,ralph lauren outlet, and then were treated with 325 ℃, 4 ℃. 475 ℃, 525 ℃ aging time of 1 hour each temperature, iO0 hours, SOOd ~,ugg outlet, lOOO-hour aging treatment,abercrombie düsseldorf, were determined by Vickers hardness and impact toughness, as shown in Table 22 and Figure l4, l5 as shown in Fig. . 1992, a decline 200Cr1sNj4Mo physical testing of rolling the chu ju Juan failure 21 (ICrl ~ Nt4Mo disheartened by the impact of low-rolling bit e2471523'7 from Table 22 and Figure 14, Figure l5 shows, 0CrI3Ni4Mo embrittlement tendency of martensitic stainless steel is small, the selected test temperature, when the long-term aging by lO0/jx impact toughness and hardness of the steel changes little, only 425 ℃ by 5O called, when the impact was significantly reduced over time, the hardness increases.

(3) steel after heat treatment system recommended treatment, with good high-temperature mechanical properties and the impact of digging through the satin, especially low-temperature impact toughness higher. (4) 475 ℃ embrittlement sensitive to Dayton to the trial that, Ocrl3Nl4Mo low-carbon martensitic stainless steel-looking female tendency of small, time after time after SOOd ~ the impact toughness of steel fell, hardness increased, which in the 42S ~ C is more obvious in the next time. Overall, the long-term aging of the steel by the organization is stable. (Continued from page 46) before the fire have not been normalized treatment due to 4 Conclusion., (I) there is a serious metallurgical raw materials such as low-quality defects times the specimen visible on a large number of small cracks and pinholes, is a failure of steel (2) gauge the carbon content of raw materials ,abercrombie singapore, does not match ~ GBSO. a 82 requirements.
