       10# seamless steel pipe mechanical properties:

       Tensile strength σb (MPa): ≥410 (42) Yield strength σs (MPa): ≥245 (25) elongation δ5 (%): ≥25 shrinkage rate ψ (%): ≥5, hardness: unheated ,≤156HB, sample size: sample size 25mm


  10# Seamless steel pipe instructions

   Used in various fields such as automobiles, machinery, construction, boilers, petrochemicals, various chain pipes, electricity, aerospace, ports, ships, bridges, sports, decoration, textile machinery and so on.


  10#Seamless steel tube procurement notice

  10#Seamless steel pipe delivery status: delivered in a state of no heat treatment or heat treatment (annealing, normalizing or high temperature tempering). Requirements for delivery in heat-treated state shall be indicated in the contract, and those not specified shall be delivered without heat treatment.


  20#Seamless steel pipe technical parameters (such as technical standards for material, process, size, etc.)

       Mechanical properties: Tensile strength σb (MPa): ≥410 (42) Yield strength σs (MPa): ≥245 (25) Elongation δ (%): ≥25 Sectional shrinkage ψ (%): ≥5, hardness : No heat treatment, ≤156HB, sample size: sample size 25mm, 20# seamless steel pipe material is 20# steel, strength is slightly higher than 15#, rarely quenched, no temper brittleness. Cold deformation plasticity is high, generally for bending, rolling, bending and hammer arch processing,


  20# seamless steel pipe performance characteristics

    Arc welding and contact welding have good welding performance, small thickness during gas welding, and parts with strict shape requirements or complex shapes are prone to cracks. The cold-drawing or normalizing state of cutting is better than the annealing state, and it is generally used to manufacture workpieces with low stress and high toughness requirements.


  20# Instructions for use of seamless steel tubes (such as use place, working principle, product structure, safety operation instructions, etc.)

   Used in various fields such as automobiles, machinery, construction, boilers, petrochemicals, various chain pipes, electricity, aerospace, ports, ships, bridges, sports, decoration, textile machinery and so on.
