12Cr1MoV Seamless Steel Pipe Prices Surge Briefly Then Trend Toward Correction

After a brief sharp surge, the price of 12Cr1MoV seamless steel pipe has approached the level before the energy-saving, emission-reduction, and power/production limits policy at the beginning of September. The market still faces uncertainty, and it may continue to consolidate weakly in the short term. The shutdown and resumption of production at steel mills in Tangshan will have a negative impact on the domestic market.

Weakening Trend in 15CrMo Seamless Pipe Market in Beijing

The price of construction steel in Beijing remains stable but slightly declining. The overall market for 15CrMo seamless pipes is relatively weak, and merchants are cautious about shipping. Many manufacturers have reduced prices, leading to short-term price fluctuations downward. The market in Tianjin is also weak, with significant inventory pressure. In Chengdu, the inventory of medium-sized plates is high, and prices may continue to weaken.

15CrMo Seamless Steel Pipe Prices Weakly Operate

With the futures market turning weak, the prices of 15CrMo seamless steel pipes have fallen sharply. New resources from steel mills are arriving, increasing supply pressure and inventory, leading the market to be pessimistic about future trends. Some small customers are eager to secure their orders, further driving prices down. In the short term, prices will continue to fluctuate.

Measures to Improve the Purity of 12Cr1MoVG Alloy Pipes

To improve the purity of 12Cr1MoVG alloy pipes, 70% high-quality scrap steel and 30% high-quality pig iron are selected during production; Al wire is added at 0.01%–0.03% during Lf refining, and Ca‑Si wire is added before the ladle is lifted; a long water mouth sleeve is used to prevent secondary oxidation; a clean intermediate bag is used to stabilize the liquid surface; the drawing speed is adjusted in a timely manner to ensure that the cast block reheat temperature is below 100°C, thereby avoiding cracks.

15CrMo Alloy Steel Pipe Element Effects and Applications

The new 15CrMo alloy steel pipe is characterized by low carbon (≤0.1%) and low sulfur (≤0.015%). Alloy elements can be divided into solid solution strengthening, grain refinement, precipitation hardening, and phase transformation strengthening based on the strengthening mechanism. Carbon forms carbides in the pipe, enhancing strength and toughness; manganese increases yield strength and impact toughness, and lowers the γ→α transformation temperature.

Characteristics of High-Pressure Alloy Pipes and Introduction to Heat Treatment Defects

High-pressure alloy pipes are primarily used in high-pressure steam boiler pipelines and must possess high strength, oxidation resistance, and stable microstructure. They are tested through water pressure tests, expansion tests, and flattening tests. Common steel grades include 20G, 15MoG, and 12CrMoVG. Seamless steel pipes used for geological drilling must withstand various stresses such as tension, compression, bending, and impact, requiring strength, hardness, wear resistance, and impact toughness.
