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. A572 Gr 42 high strength 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.
At the same time of doing well in A572 Gr 42 high strength steel production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A572 Gr 42 high strength steel technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in A572 Gr 42 high strength steel etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.
