What is S690QL young modulus equivalent JIS steel grade

Looking to the future, our company will make its main business more competitive while carrying out diversified, extensive, green and harmonious development modes, so as to be the most competitive S690QL young modulus producer in the world as well as a worldwide first-class enterprise. With ten years cooperation with these big mills, now we are the agent of super stainless steel mills in China.

A514 gr M alloy structural steel chemical composition (melting analysis)%C: 0.12-0.21, Si: 0.20-0.35, Mn: 0.45-0.70, P max.: 0.035, S max.: 0.035, Ni: 1.20-1.50, Mo: 0.45-0.6.0, B: 0.001-0.005The mechanical properties in thickness (mm)T≤65Yield strength (≥Mpa): 690Tensile strength (Mpa):760-895Elongation in ≥, %: 18

In recent years, in line with the development trend of iron and S690QL young modulus steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which S690QL young modulus are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

The main function of boron in S690QL young modulus and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
