Hollow Rod 4130 Seamless Steel Tube
4130 hollow rod has high strength and toughness, high
hardenability, and the critical hardening diameter in oil is
15-70mm; the thermal strength of steel is also good, and it has
sufficient high-temperature strength below 500°C, but at 550°C Its
strength drops significantly; when the alloying elements are at the
lower limit, the welding is quite good, but when it is close to the
upper limit, the weldability is moderate, and it needs to be
preheated to above 175°C before welding; the machinability of the
steel is good, and the plasticity is medium during cold
deformation; The range of 300 ~ 350 ° C has the first type of
temper brittleness; there is a tendency to form white spots.

4130 hollow rod is usually used in quenched and tempered state,
when the carbon content is the lower limit steel can also be used
as carburized steel that requires higher core strength. In the
medium-sized machinery manufacturing industry, it is mainly used to
manufacture quenched and tempered parts with large cross-sections
and working under high-stress conditions, such as shafts, main
shafts, and high-load control wheels, bolts, stud bolts, gears,
etc.; in the chemical industry It is used to manufacture welded
parts, welded structures composed of plates and pipes, and
high-pressure conduits whose temperature does not exceed 250°C in a
medium containing nitrogen and hydrogen; it is used to manufacture
fasteners that work below 450°C in the steam turbine and boiler
manufacturing industries. Flanges and flange covers subject to high
pressure below 500 °C.
We specialize in all kinds of imported and domestic high-pressure
boiler tubes, petroleum cracking tubes, alloy steel, stainless
steel, low temperature resistant, corrosion resistant steel, alloy
pipe fittings and special steel materials, etc.
The company has three seamless steel pipe piercing production
lines, six hot rolling production lines, and nine cold drawing
production lines. The company can currently produce alloy seamless
steel pipes, structural pipes, thick-walled seamless steel pipes,
Special seamless steel pipes such as seamless steel pipes for oil
cylinders, fluid delivery pipes and special-shaped seamless pipes
can also be customized according to customer requirements.
Thick-walled steel pipes, customized oval seamless pipes, seamless
square pipes, rectangular pipes, hexagonal pipes, outer circle
inner oval pipes, inner thread seamless pipes, outer flat inner
circle and other special-shaped steel pipes. Products are widely
used in engineering, coal mines, textiles, electric power, boilers,
machinery, military and other industrial fields.
