Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the NM450 steel yield strength project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of NM450 steel yield strength customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
Q235 steel is ordinary carbon structural steel, also called Q235 ms plate. Q235 steel plates are popular among a large number of buildings and engineering structures. Q235 steel can be used to make steel bars or to build workshop frames, high-voltage transmission towers, bridges, vehicles, boilers, vessels, ships, etc. Q235 steel is also widely used as NM450 steel yield strength mechanical parts with low performance requirements. Sometimes Q235C steel and Q235D steel can also be used as special steel.
Chemical composition of NM450 steel yield strength, Q345D steel plate: C: ≤0.18; Si: ≤0.50; Mn: ≤1.70; P: ≤0.030; S: ≤0.025; Nb: ≤0.07; V: ≤0.15; Ti: ≤0.20; Cr: ≤0.30; Ni: ≤0.50; Cu: ≤0.30; N: ≤0.012; Mo: ≤0.10; Als: ≥0.015. Yield strength (MPa) of Q345D steel plate: ≤16mm: ≥345; 16-40mm: ≥335; 40-63mm: ≥325; 63-80mm: ≥315; 80-100mm: ≥305; 100-150mm: ≥285; 150-200mm: ≥275; 200-250: ≥275; 250-400: ≥265. Tensile strength of Q345D low alloy steel: 450-630(MPa). Elongation: ≥21. Impact test: -20 ℃: ≥34.
NM450 steel yield strength, Wear resistant steel plate has good wear resistance:The chemical composition of the alloy wear-resistant layer is 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%. The macro hardness is HRC56-62 and the hardness of chromium carbide is HV1400-1800. Because the carbides are distributed perpendicularly in the direction of wear, even when compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
