Methods to improve the toughness of KF40 ocean engineering steel plate

Wear resistant steel plate KF40 ocean engineering steel plate is widely used in engineering, mining, construction, agriculture, cement production, port, electric power, metallurgy and other mechanical products, which require high strength and wear resistance. Such as bulldozers, loaders, excavators, dump trucks and various mining machinery, grab, stacker reclaimer, conveying bending structure, etc. The wear resistant steel plate KF40 ocean engineering steel plate can obtain good combination of strength and toughness through scientific quenching and tempering process, which can also improve the steel hardness to achieve the purpose of wear resistantance.

The company has allocated special environmental protection facilities for all KF40 ocean engineering steel plate pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, KF40 ocean engineering steel plate steel mill scale, environmental protection dust has reached 100%.

We do sand blasting and shop primer for various KF40 ocean engineering steel plate steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer KF40 ocean engineering steel plate thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.

KF40 ocean engineering steel plate controlled rolling is that, on the basis of adjusting the chemical composition of KF40 ocean engineering steel plate, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of KF40 ocean engineering steel plate.

Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
