Product Description
34CrMo4 1.7220 +QT Alloy Steel Tube
We offer a comprehensive range of Alloy Steel Tubes that are appreciated for superior quality and unmatched durability. These are available in different sizes, grades, specification and shapes. We can manufacture such as Seamless Pipes & Tubes as per ASTM /EN /DIN standards & other international standards. It can customize this alloy steel pipes & tubes as per the requirements of the clients.
Application
Alloy Steel Tube have hollow sections and are widely used as pipelines for conveying fluids, such as oil, natural gas, gas, water and some solid materials. It is widely used in manufacturing structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Manufacturing annular parts with alloy steel tubes can improve material utilization rate, simplify manufacturing process, save material and processing time, such as rolling bearing rings, Jack sleeves, etc.Size Range
Outside Diameter : 30-850mm ;Wall Thickness : 3-100mm ;
Length max 15000mm Single Random, Double Random & Required Length.

Packages
all of our steel products are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished pipes together in batches. However, for some special pipes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation. For enhanced customer experience, we also provide dedicated package as per your special requirements.Logistics
By default, we will quote based on sea transportation, such as FOB, CFR, CIF, DDU, DDP and the like for most enquiries or orders. Quotation based on air transportation is also optional upon your request for urgent demands.
