Quenching and tempering treatment of 40Cr steel pipe 


Cr can increase the hardenability of 40Cr steel pipe, improve the strength and tempering stability of 40Cr steel pipe, and have excellent mechanical properties. Katalor has the large stockist of 40Cr steel pipe, we can export to all over the world.


40Cr steel pipe should be oil-cooled after quenching. 40Cr steel pipe has good hardenability, can be hardened by cooling in oil, and the deformation and cracking tendency of the workpiece is small. However, in the case of tight oil supply, small enterprises can quench the water in the shape of 40Cr steel pipe uncomplicated workpieces.

The hardness of the 40Cr steel pipe is still high after quenching and tempering, and the second tempering temperature is increased by 20~50ºC. Otherwise, the 40Cr steel pipe hardness is difficult to reduce.

After the 40Cr steel pipe is tempered at high temperature, the shape is complicated to be cooled in the oil and simply cooled in water, in order to avoid the influence of the second type of temper brittleness. 40Cr steel pipe after tempering and cold cooling, if necessary, stress relief treatment.

We can supply the 40Cr steel pipe with high quality. So if you are interested in 40Cr steel pipe, you can contact us free. We have 40Cr steel pipe with different size to meet your any requirements. Please contact at first time!

Market status of ASME SA213 T5 boiler pipe this week With the need of the policy, the market status of ASME SA213 T5 boiler pipe  is changing. Katalor as a professional steel supplier and exporter in China. We produce  ASME SA213 T5 boiler pipe with good quality and best service. Now Katalor will analyze the market of  ASME SA213 T5 boiler pipe  for you. This week's ASME SA213 T5 boiler pipe markept continued to remain strong, but in the strong environment of the operation, it gradually showed the characteristics of the off-season. With the arrival of the wheat harvest season, the impact of high temperature and rainy weather gradually increased, the overall inventory decline rate slowed down significantly. ASME SA213 T5 boiler pipe  inventories fell by 360,000 tons this week, which has narrowed for two consecutive weeks, down 100,000 tons from last week, down 250,000 tons from last week, down 100,000 tons fro...
