Zhuhai 12Cr1MoV alloy tube news


The stock of alloy tube market manufacturers is still low. And the end of the year is coming, funds are still tight, steel market pressure is still large. At the same time, the number of new export orders is less, and the pessimistic attitude of businessmen to the future market remains unchanged. Therefore, it is expected that the overall Tangshan billet market will maintain a weak adjustment market today, and there is still room for further decline. The market of steel-making pig iron is weak and stable, and the transaction of alloy tube is still not improved. This week, the price drop of steel-making pig iron has expanded compared with that of last week, about 20-180 yuan / ton. The transaction volume in some regions has further weakened, and the decline is larger in Shanxi area of Hebei Province, which is mainly affected by the big drop of steel billet. Some manufacturers are pessimistic and stop quoting, and the inventory has a slight upward trend. Near the end of the month, the steel plant procurement price has not changed, the procurement situation is still poor. The short-term market does not have factors for improvement, and the downturn is likely to continue. It is not ruled out that prices in some regions will fall with each other. Today's iron ore market stable operation, alloy tube transaction price slightly loose. Recently, the import ore market was slightly weak. Yesterday evening, the price of iron ore dropped by 0.5 U.S. dollars, which restrained the rising trend of the market. Today, the spot trading volume and price of iron ore in the port have been withdrawn. The buyer's willingness to lower the price is obvious, and the seller's enthusiasm for shipment has increased. Therefore, the market price has declined slightly.

Knowledge of Zhuhai 12Cr1MoV alloy tube


The variation of stacking fault energy with the number of elements was measured by XRD. It can be seen that the stacking fault energy from Ni to CONI decreases a lot, but with the increase of element types, the rate of reduction of stacking fault energy slows down. It is mainly due to the increase of lattice distortion energy and the release of stacking fault energy due to the adjustment of atomic position. Generally, the increase of element types in alloy steel pipe will enhance the effect of these two aspects, but theoretical derivation and explanation are still needed. At present, many literatures have found that the self diffusion coefficient of elements is one order of magnitude lower than that of multi-component alloys.
Three diffusion couples Cr Mn, Fe Co and Fe Ni were designed by pseudo binary alloy. It can be found that the Q / T of Cr, Mn, Fe, CO and Ni in crmnfeconi high entropy alloy is the largest, that is to say, the diffusion coefficient is the smallest, which indicates that the diffusion rate of atoms in the high entropy alloy is slower than that in other alloys. This is due to the interaction between different atoms and lattice distortion in alloy steel pipe, which seriously affects the effective diffusion rate of atoms. Generally, the phase transformation requires the CO diffusion between the principal components to achieve phase separation equilibrium, so the hysteresis diffusion effect will affect the formation of new phase in alloy steel pipe.
