The welding technology of popular 09CuPCrNi-B steel

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and popular 09CUPCRNI-B steel resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, popular 09CUPCRNI-B steel new materials, and promotes the competition of enterprises Struggle.

Application of 30CrMnSiA steel, popular 09CUPCRNI-B steel:30CrMnSiA steel is generally used after quenching and tempering. 30CrMnSiA steel is mainly used to manufacture various important parts with high load and high speed, such as gears, shafts, clutch friction plates, sprocket wheels, grinding wheel shafts, shaft sleeves, bolts, nuts, etc. 30CrMnSiA steel is also used for manufacturing wear-resistant parts with low working temperature and variable load welding components, such as blades, valve plates and non corrosive pipes and pipes of high-pressure blowers.

Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel, such as strength, toughness, ductility, forming, welding and cutting, abrasion, high temperature, fatigue and so on. The weathering resistance of weathering steel is 2-8 times of that of plain carbon steel popular 09CUPCRNI-B steel, and the coating property is 1.5-10 times of that of plain carbon steel. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, etc..

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 popular 09CUPCRNI-B steel 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 popular 09CUPCRNI-B steel seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

42CrMo alloy steel popular 09CUPCRNI-B steel: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.
