How to improve toughness of 09cuptire-a grade tbt

Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel 09CUPTIRE-A grade tbt can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with 09CUPTIRE-A grade tbt good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.

The correct choice of billet type, section shape, size and weight are of great significance to 09CUPTIRE-A grade tbt steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The 09CUPTIRE-A grade tbt rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.

The basic principle of 09CUPTIRE-A grade tbt, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

Our company will accept the product quality objection registration record, pass it to the 09CUPTIRE-A grade tbt production unit and relevant departments, and timely coordinate the supervision of product 09CUPTIRE-A grade tbt quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
