S690QL steel plate china size range

S690QL steel plate china, 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.

According to the separate performance report released by India's Jindal stainless steel (Sisal) Co., Ltd. (JSHL), as of March 31, 2020, due to the global economic slowdown, epidemic situation, imports and other factors, its S690QL steel plate china stainless steel sales decreased by about 10% to 600000 tons from 667000 tons in the previous fiscal year, and its net sales decreased by nearly 7% to 83.396.9 billion rupees, with the same gross operating profit (EBITDA) After tax profit increased by 22.4% to 3.203 billion rupees. The adoption of the new tax system has a positive impact of RS 220 million on after tax profits.

With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched S690QL steel plate china increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of S690QL steel plate china during tempering, while tempering determines the performance and life of the workpiece.
