China supplier chemical composition of nm400 yield strength

Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical chemical composition of NM400 personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and chemical composition of NM400 after-sales service of the project.

Thin steel plate is a kind of steel plate material that is thinner in thickness. Generally, steel plate with thickness less than or equal to 4mm is called thin steel plate. As we all know, the steel products we usually see are also divided into different thicknesses. The strength, performance and scope of application of different thickness steel plates, chemical composition of NM400 are also different. Today, we will talk about some related knowledge of thin steel plates, and take you to understand the characteristics and uses of thin steel plates.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. chemical composition of NM400, Q420C steel has good mechanical properties and weldability, good cold and hot workability.

904L corrosion-resistant steel is developed with various sulfuric acid corrosion applications. 904L corrosion-resistant steel has high chromium content and enough nickel content. The addition of copper makes 904L corrosion-resistant steel have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking, and its pitting corrosion resistance is slightly better than other steels, such as chemical composition of NM400.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.

Keep close relationship with all manufacturers and users, cooperate sincerely, share weal and woe together. We are deeply tolerant of travelling with you! We value and value each other's career and friendship. No matter when and where, all our staff will spare no effort to put into the work, and do their best to provide chemical composition of NM400 satisfactory services for all friends, so as to achieve win-win and multi win for each other.
