Online Q355GNH steel order standard pdf

The ASTM A36 I beam has moderate tensile and yield strength because of its low carbon content and no other alloying elements. A36 steel beam Online Q355GNH steel order is commonly used in construction and civil engineering because of its competitive low cost and good welding, forming and processing properties. The hot-dip galvanized carbon steel beam can effectively protect the steel from the corrosion of weather and environment. The amount of zinc Online Q355GNH steel order plating can be customized according to your requirements.

The company always adheres to the Online Q355GNH steel order principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great Online Q355GNH steel order cause. Customers are welcome to visit our company at any time. We are always ready to support you.

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of Online Q355GNH steel order high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's Online Q355GNH steel order technical equipment.

With the increase of temperature, the yield limit of Online Q355GNH steel order will decrease monotonically, but the tensile strength of Online Q355GNH steel order will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of Online Q355GNH steel order. Near the blue brittleness temperature, the Online Q355GNH steel order strength increases and the plasticity decreases. The elongation and section shrinkage of Online Q355GNH steel order increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel Online Q355GNH steel order plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
