Pipeline steel plays an important role in pipeline transportation. How many types of HARDOX 400 equivalent material, pipeline steel are there? At present, pipeline steel can be divided into the following four categories according to microstructure. First, pearlitic pipeline steel. The basic components of pearlitic pipeline steel are carbon and manganese, generally speaking, the content is 0.10% - 0.20%, and the manganese content is 1.30% - 1.70%. It is generally produced by hot rolling or normalizing heat treatment process. Second, acicular ferrite pipeline steel. Third, martensitic pipeline steel. Fourth, tempered sorbite pipeline steel.
The difference between Q195 steel and 20# steel: HARDOX 400 equivalent material, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.
As the thickness and hardness of HARDOX 400 equivalent material increase, the tendency to crack at the cutting edge increases. In order to prevent the HARDOX 400 equivalent material from cutting cracks, preheating should be carried out before HARDOX 400 equivalent material cutting. Special attention should be paid to preheating to make the entire HARDOX 400 equivalent material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole HARDOX 400 equivalent material cannot be preheated, the partial preheating method can be used instead.
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. HARDOX 400 equivalent material, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
