The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, ,A514 Gr M alloy steel plate.
A514 Gr M alloy steel plate,After quenching and tempering, 40Cr alloy steel plate and sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A514 Gr M alloy steel plate is good. It can be hardened to Ф28 ~ 60mm during water quenching and Ф15 ~ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ~ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
First of all, we should establish a correct concept of after-sales service Service concept is an important part of corporate culture and a long-term enterprise value concept Our company's after-sales service embodies the concept of "customer first, sincere service for customers" As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns,A514 Gr M alloy steel plate.
