A573 Gr 70 structural steel,The carbon A573 Gr 70 structural steel content of the pipeline steel is required to be low, and the strength of the pipeline steel is ensured by increasing the manganese content and adding trace elements such as niobium, titanium, vanadium and molybdenum. For pipeline steel, in addition to the required strength and plasticity index, the requirement for toughness index is an outstanding feature, including the impact energy of pipeline steel plate, impact transition temperature and toughness index of welding heat affected zone and welding metal. In addition, there are requirements for strain aging, weldability, stress corrosion and other indicators.A573 Gr 70 structural steel
Q235NH corrosion-resistant steel plate full name: atmospheric corrosion-resistant hot continuous rolled steel, also known as Corden steel, widely used in: containers, power plants, chimney and railway engineering, such as large outdoor sculpture steel. The corrosion-resistant steel plate (i.e. atmospheric corrosion resistant steel) is a low-alloy steel series with low price and good quality, which is between ordinary steel such as and stainless steel The corrosion-resistant steel can be continuously developed and innovated after being integrated into modern metallurgical new mechanism, new technology and new process It is one of the series of steel with world advanced super steel technology,A573 Gr 70 structural steel.
A573 Gr 70 structural steel,The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.
GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.
