What is the A573 Gr 70 equivalent Q390E carbon plate machining

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and A573 Gr 70 equivalent Q390E carbon plate heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported A573 Gr 70 equivalent Q390E carbon plate to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

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 A573 Gr 70 equivalent Q390E carbon plate 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.

Low carbon steel is a carbon steel with a carbon content of less than 0.25%.
Low carbon steel A573 Gr 70 equivalent Q390E carbon plate is also called soft steel or mild steel because of its low strength and low hardness. Low carbon steel includes most common carbon structural steel and a part of high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, and some A573 Gr 70 equivalent Q390E carbon plate are carburized and other heat treated for mechanical parts that require wear resistance.

For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.
