Manufacturing process of TMCP NV E engineering ship steel

Manufacturing process of TMCP NV E engineering ship steel

At the same time, the company operates a variety of products of related iron and TMCP NV E engineering ship steel steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained TMCP NV E engineering ship steel ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

ASTM A441, used in low-tolerance, state-of-the-art structures, such as towers and large telescopes, TMCP NV E engineering ship steel is a high-strength structural grade with a yield strength of 40,000 to 50,000 psi and an allowable bending stress of 24,000 to 30,000 psi.

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel TMCP NV E engineering ship steel 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.

Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following TMCP NV E engineering ship steel basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.

TMCP NV E engineering ship steel, Low alloy steel plate is a general designation, mainly refers to the steel plate with alloy content less than 3.5%. Alloy steel in the market is distinguished by the total amount of alloy elements, mainly including low alloy steel, medium alloy steel and high alloy steel. When the total alloy amount is less than 3.5%, it is called low alloy steel; if the total alloy amount is 5-10%, it is medium alloy steel; and when the total alloy amount is more than 10%, it is high alloy steel.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
