Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.

Compared with ordinary steel, structural steel has the following differences. First, the strength of structural steel is high, and its bearing capacity is far greater than that of ordinary steel. Second, the structural steel has low impurity and carbon content, uniform material and good performance. Third, structural steel has light weight and is suitable for building various frames. Fourth, it is convenient to build structural steel, which is conducive to construction efficiency and reduces construction time. In some construction fields, structural steel must be used. Where can we find NM450 plate application, structural steel suppliers?

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. NM450 plate application, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785

BBN had provided NM450 plate application Hardox plates for more than 15 years for widely applied in coal mining machinery, cement equipment, road construction machinery, engineering machinery, dump trucks, metallurgical area and port fields. In 2016,we brought our customer to visit our NM450 plate application NM400 steel plate producing line and our Shanghai warehouse for 30000 tons plate and structure. As a result, Our client purchased 500 tons NM 400 as first order, which is shipped by 3 times. In future, BBN will always guarantee that all the delivery condition for Hardox plate provided will be with quenching and tempering, which is the best delivery type according GBT 24186 standard.
