09CuPCrNi-B steel yield equivalent BS grade

Q690E material has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance. In addition, 09CUPCRNI-B steel yield, Q690 high strength steel plate and sheet has good corrosion resistance and certain wear resistance. High strength, especially in the normalizing or normalizing plus tempering state has a higher comprehensive mechanical properties.

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 09CUPCRNI-B steel yield 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.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched 09CUPCRNI-B steel yield increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of 09CUPCRNI-B steel yield during tempering, while tempering determines the performance and life of the workpiece.

The steel such as 09CUPCRNI-B steel yield delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our 09CUPCRNI-B steel yield service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's 09CUPCRNI-B steel yield customer service to establish a good, comprehensive, full service system.
