Supply the sa573gr.70 chemical composition application

Q420q steel material is a kind of structural steel plate for bridges, the grades are Q420qD, Q420qE, Q420qF.
Q420q steel chemical composition: C: ≤0.11, Si: ≤0.55, Mn: 1.0-1.7, Nb: 0.01-0.09, V: 0.01-0.08, Ti: 0.006-0.03, Cr: ≤0.50, Ni: ≤0.30, Cu: ≤0.30, N : ≤0.008, Al: 0.01-0.045.Steel delivery status: delivered in the thermomechanical rolling state, and the steel plate should be trimmed for delivery.

The company sold 50,000 tons of hot rolled plates to Southeast Asian countries, which will help the construction of relevant sa573gr.70 chemical composition key projects in countries along the “Belt and Road”. In response to the local environment and construction needs in Southeast Asia, the company has made a number of improvements to its export products, with excellent cost performance such as low emissions and low fuel consumption. It is an ideal compaction equipment for the sa573gr.70 chemical composition construction of high-grade highways, railways, airports, ports and industrial sites. Loved by customers from countries along the “Belt and Road”.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of sa573gr.70 chemical composition, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
