Why should 1.8983 steel equivalent be cut and heat treated

1.8983 steel equivalent, Q345C steel plate is a kind of weldable low carbon engineering structure material, which is generally produced by continuous rolling mill. The carbon content of Q345C steel plate is less than 0.25%. The yield strength σ0.2 of Q345C steel plate is 300- 800MPa and the yield ratio is 0.65- 0.95. Q345C steel plate has excellent low temperature toughness. That is mainly owe to the solid solution of alloy elements (Mn, Si, Al, Cr, etc.), grain refinement (Nb, V, Ti, etc.), precipitation hardening (Nb, V, Ti, etc.), phase transformation strengthening (Mn, Si, Mo, etc.), and controlled rolling and controlled cooling, etc. new technologies.

Hyundai Steel Co. has no plans to cut production further despite weak steel demand due to the coronavirus pandemic, the company's president said. Earlier this year, South Korea's second largest steelmaker reduced its 1.8983 steel equivalent annual production of hot rolled coils from 1 million tons previously to 700 thousand tons per year for EAFs. A turnaround is expected after the third quarter of this year.

High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the 1.8983 steel equivalent, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.

Over the years, the company has maintained long-term stable business relationships with major domestic steel mills and foreign steel companies. The company's main boiler and pressure vessel steel plates, low alloy high-strength steel plates, wear-resistant steel plates, corrosion-resistant steel plates, 1.8983 steel equivalent bridge steel plates , strucural teel plates, steel plates for alloy structures, mold steel plates, steel plates for shipbuilding and production platforms, composite steel plates, steel plates for oil and gas pipelines.
