ASTM 4135 alloy structural steel pipe has high static strength, impact toughness, and high fatigue limit. Its hardenability is higher than that of 40Cr steel, and it can maintain high creep strength and durable strength at high temperatures, and its long-term working temperature can reach 500°C. During cold deformation, its plasticity is at a medium level, but its weldability is poor. At low temperatures of -110 degrees Celsius, it has high static strength, impact toughness and high fatigue strength, good hardenability, no overheating tendency, small quenching deformation, and acceptable plasticity during cold deformation. The resistance is at a medium level, but it has the first type of temper brittleness and poor weldability. It needs to be preheated to 150~400 degrees Celsius before welding, and post-weld heat treatment is required to eliminate stress. Generally, it is used after quenching and tempering, and can also be used after high and medium frequency surface quenching or quenching and low and medium temperature tempering.

astm 4135 steel pipe


 ASTM 4135 alloy structural steel pipes are widely used in the oil and gas industry to manufacture transportation pipelines, oil well pipelines, and oil drilling pipelines. ASTM 4135 pipes need to have high strength, corrosion resistance, and high-temperature resistance to withstand high pressure and high-temperature environments. ASTM 4135 alloy structural steel pipe meets these requirements and provides reliable performance under harsh operating conditions.

34CrMo4 steel pipe


 ASTM 4135 alloy structural steel pipes are widely used in the field of mechanical engineering to manufacture various mechanical parts. These parts include bearings, gears, connecting rods, crankshafts, etc. ASTM 4135 alloy structural steel pipe has high static strength and impact toughness and can withstand high loads and impact loads. It also has good wear resistance and can provide reliable performance under conditions of high load and high-speed movement.

En 1.7220 steel pipe


ASTM 4135 alloy structural steel pipe is widely used in construction and bridge engineering to manufacture supporting and connecting components. These components need to have high strength and rigidity to withstand heavy loads and external forces. ASTM 4135 alloy structural steel pipe has the high strength and stiffness to meet these requirements and provide reliable performance in harsh environmental conditions.
