Common advantages of q235 carbon steel

The addition of Ca element in steel such as q235 carbon steel can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.

The carbon tool steel thick plate is made of carbon tool steel and is made by hot rolling.This carbon tool steel has good cold and hot processing performance, high hardness and plastic resistance, low production cost and wide range of uses. q235 carbon steel, Carbon tool steel is usually delivered in an annealed or high temperature tempered state. It is mainly used to manufacture cutting tools, measuring tools and molds with low cutting speed, simple shape and low precision. The thickness of the steel plate is 4.5-25mm, and the width and length comply with GB709 regulations.

This week, the domestic welded pipe market prices have stabilized as a whole, with high inventories. As of January 29, the average price of 4 inch * 3.75mm welded pipes in 27 major cities across the country was 4708 yuan/ton, which was an increase of 7 yuan/ton from the average price of 4701 yuan/ton last Friday. In terms of inventory: the national inventory of welded pipes on January 29 was 904,900 tons, an increase of 41,100 tons from 863,800 tons last Friday.
