impact resistance of nm400 steel plate Mn element content

How much is the marine steel per ton?According to the difference of quality grade and strength grade, as well as the difference of plate size, production area, and user requirement, the price of impact resistance of NM400 steel plate plate fluctuates greatly. At present, the market price of marine plate is about 3800 yuan per ton to 5800 yuan per ton. Generally, the most commonly used marine plate price is about 4000 yuan per ton.

The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the impact resistance of NM400 steel plate industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the impact resistance of NM400 steel plate industry with scientific management, high quality, first-class service and harmonious development

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 impact resistance of NM400 steel plate 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.

Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with impact resistance of NM400 steel plate, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel impact resistance of NM400 steel plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
