Product Description

SAE1020 low-carbon steel pipe 100mm 20mm diameter 20CR4 precision seamless steel pipe


The essence of high-temperature tempering brittleness of precision bright tubes is generally believed to be the result of impurity elements such as phosphorus, tin, antimony, and arsenic segregation at the original austenite grain boundaries, leading to grain boundary embrittlement. And alloy elements such as manganese, nickel, chromium, and the above-mentioned impurity elements undergo co segregation at grain boundaries, promoting the enrichment of impurity elements and exacerbating embrittlement. On the contrary, molybdenum has a strong interaction with impurities such as phosphorus, which can generate precipitates within the crystal and hinder the segregation of phosphorus at grain boundaries. This can alleviate the high-temperature tempering brittleness of rare earth elements, which also has a similar effect to molybdenum. Titanium more effectively promotes the precipitation of phosphorus and other impurity elements within the crystal, thereby weakening the grain boundary segregation of impurity elements and slowing down high-temperature tempering brittleness.
