The physical properties of L360 steel pipe mainly depend on its material strength. Material strength refers to the maximum stress that the steel pipe can withstand under stress. This steel has a high yield strength, usually around 360MPa, which makes L360 steel pipe have a high load-bearing capacity when subjected to pressure and load.
The physical properties of L360 steel pipe mainly include the following aspects:
Yield strength: The yield strength of L360 steel pipe ranges from 360-530MPa, which indicates the minimum stress value at which it can resist plastic deformation when subjected to pressure.
Tensile strength: The tensile strength of L360 steel pipe ranges from 460-755MPa, which is the maximum stress value at which the material resists fracture under tension.
Elongation: The elongation of L360 steel pipe is 21%, which indicates the amount of plastic deformation that the material can withstand during stretching.
Impact test: The impact test value of L360 steel pipe at -20℃ is 90J, which indicates that its toughness at low temperatures is good.
