weather resistant SPA-H steel material heat treatment

Some , low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but also in some cases take appropriate precautions and even be exposed to the atmosphere without coating Elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel, and molybdenum The excellent atmospheric corrosion resistance has led to the formation of new concepts for structural design of buildings, bridges, and other structures,weather resistant SPA-H steel.

20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than , No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as , but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc 20G steel is most suitable for use in medium and low pressure boilers,weather resistant SPA-H steel.

Weather resistant SPA-H steel,Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
