A573 Grade 58, 65, 70 hot rolled plate main advantages in BBN steel

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for A573 Grade 58, 65, 70 hot rolled plate various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several A573 Grade 58, 65, 70 hot rolled plate after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel A573 Grade 58, 65, 70 hot rolled plate is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.

Laser cutting, it is a specific way of cutting A573 Grade 58, 65, 70 hot rolled plate steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting A573 Grade 58, 65, 70 hot rolled plate speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.

In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
