Recommended heat treatment temperature: normalizing 850, quenching 840, tempering 600. 45# seamless steel pipe is high-quality carbon structural steel with low hardness and easy cutting processing. It is commonly used in molds as templates, tips, guide po

The quenching hardness of 45# seamless steel pipe is between HRC20~HRC30; the quenching hardness of 45# seamless steel pipe is between HRC55~58, and the limit value can reach HRC62; the 45# seamless steel pipe must be placed for 15-20 days before it can b

EN 10216-1 seamless steel tube series specifies standards for cold-worked precision steel tubes of various sizes. Precision steel tubes are increasingly used in mechanical engineering due to the continuous dimensions and improved tolerances and surfaces o

DIN 17172 STE 360.7 seamless steel pipe is usually untreated after rolling, pressing or stretching hot forming operations, provided that the hot forming operations achieve irredeemable structural conditions and are sufficiently uniform that no further col
