How to choose the material and specification of material HARDOX 400 steel, boiler tube? First, select the specification according to the actual use. Secondly, material: the suitable boiler tube material is different for different use scenarios. Thirdly, the wall thickness of the boiler tube should be strictly in accordance with the relevant standards. If the thickness is not up to standard, it is easy to cause accidents, so it must be strictly controlled. Finally, the boiler tube should be checked in time when receiving the goods, and the relevant instruments should be used to detect whether the steel quality has reached the standard, if not, it can be rejected.
In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product material HARDOX 400 steel structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel material HARDOX 400 steel supplier in the world.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized material HARDOX 400 steel are higher than that of annealed material HARDOX 400 steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of material HARDOX 400 steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.
The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for material HARDOX 400 steel.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
