What is the weight of q245r equivalent astm material?

The development q245r equivalent astm material of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with q245r equivalent astm material high-quality and efficient services, work together for win-win, and create a better tomorrow!

Grade S355J2 is an unalloyed welded structural steel with guaranteed impact work at a temperature of -20ºС. It is used in industrial and civil engineering, as well as in the construction of oil and gas platforms, other offshore structures, power transmission towers and other metal structures. Steel S355J2 is actively used to manufacture elements of heavy ground and underground equipment (bulldozers, excavators and dump trucks), railway wagons and agricultural machinery.

Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the q245r equivalent astm material alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the q245r equivalent astm material wear-resistant property to meet the requirements of specific working conditions.

Alloying elements can strengthen the properties of structural steels. q245r equivalent astm material, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for q245r equivalent astm material, 42CrMo steel is quenching and tempering.
