What is per pieces weight of SA709 Gr 50W carbon steel plate sheet

The main materials of weathering steel are: Q355GNH, 09CuPCrNiA, 05CuPCrNi, Q345NH, Q235NH, Q295NH, SA709 Gr 50W carbon steel plate sheet, Q275NH, Q355NH weathering steel plate. Weathering steel plate products are widely used in outdoor, indoor decoration, twilight wall decoration and used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing corrosive media in chemical oil equipment.

Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel SA709 Gr 50W carbon steel plate sheet can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

SA709 Gr 50W carbon steel plate sheet product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering

Hydrogen (H) is the most harmful element in general steel such as SA709 Gr 50W carbon steel plate sheet. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
