Description
Chromoly 4130 alloy steel tubing for E-bike frame pipe auto part pipe steel tube is widely used, mainly for the manufacture of water wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arched brick pipes.A seamless steel pipe is a circular pipe having a hollow section and no seams around it. The seamless steel pipe is made of carbon steel, alloy steel, stainless steel ingot or solid tube blank, and then is made by hot rolling, cold rolling or cold drawing.Seamless steel pipes have a hollow section and are used in large quantities as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials.
Brief Introduction Of 3004 Aluminium/Aluminum Alloy 
3004 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It is similar to the 3003 alloy, except for the addition of approximately 1% magnesium. It can be cold worked (but not, unlike some other types of aluminium alloys, heat treated) to produce tempers with a higher strength but a lower ductility. Like most other aluminium-manganese alloys, 3003 is a general-purpose alloy with moderate strength, good workability, and good corrosion resistance. It is commonly rolled and extruded, but typically not forged. As a wrought alloy, it is not used in casting.
The alloy 3004 is commonly used in the making of beverage cans. It was developed to satisfy the need for thinner gauges in can-stock, and thereby to some extent replaced its predecessor 3003 alloy in the making of beverage cans. Can-stock can be made thinner due to the addition of 1% magnesium, which contributes in solid solution strengthening.
Machinability:
Aluminium / Aluminum  3004 alloy has good machinability in the hard temper. Oil lubricant is used for performing machining operations.
Forming:
Aluminium / Aluminum  3004 alloy can be formed using conventional hot working or cold working methods.
Welding:
The Aluminium / Aluminum  3004 alloy can be welded using TIG or MIG welding techniques.
Heat treatment:
Aluminium / Aluminum  3004 alloy is a non-heat treatable alloy.
Forging:
Aluminium / Aluminum  3004 alloy is forged at temperatures ranging from 372 to 510°C (700 to 950°F).
Hot Working:
Aluminium / Aluminum  3004 alloy is hot worked at 260 to 483°C (500 to 900°F).
Cold Working:
Aluminium / Aluminum  3004 alloy can be cold worked up to 75% reduction of area using conventional techniques. This process should be followed by annealing if it is cold worked beyond 75% reduction of area.
Annealing:
Aluminium / Aluminum  3004 alloy is annealed at 344°C (650°F) followed by cooling in air.
Hardening:
Aluminium / Aluminum  3004 alloy can be annealed by cold working.
Applications:
Aluminium / Aluminum  3004 alloy is used in sheet metal work. It is also used in manufacturing storage tanks.
