4130 Chromoly Tubing in India
For industrial buyers in India, 4130 tubing is a specified engineering material bought against a drawing or a customer's standard. The questions that matter are the exact grade, the standard and the proof of compliance.
Grade and Standard in the Indian Context
Indian drawings may call the same family of steel by different names. 4130 is the AISI and SAE designation; European documents use 25CrMo4; Indian standards have their own chromium-molybdenum grades of similar composition. These grades are close but their composition limits differ, so do not treat them as interchangeable without checking the drawing. If your customer names AISI 4130 to ASTM A519, order exactly that.
The 4130 equivalent material page sets the grades side by side.
Supply for Industrial Users
Machine builders, hydraulic equipment makers and tool rooms typically need heavier walls and machining-grade conditions, while vehicle builders need thin structural tube. Both are supplied with mill test certification, and material can be cut to length before dispatch. For a broader view of domestic supply see 4130 chromoly tubing across India.
Sectors That Use 4130 Tubing
Across Indian industry the alloy appears in vehicle testing and prototype work, in defence and aerospace supply chains, in hydraulic and pneumatic equipment, in oil and gas tooling and in general machine building. Each sector has its own paperwork. Defence and aerospace orders usually specify the standard and inspection in detail; machine builders often work from a drawing with a grade and hardness. Send the drawing or specification with your enquiry so that the offer matches it exactly.

Frequently Asked Questions
Is 4130 the same as an Indian standard Cr-Mo grade?
Similar grades exist, but composition limits differ. Supply should match the grade and standard named on your drawing.
Can I get 4130 tubing in annealed condition for machining?
Yes. State annealed condition on the enquiry.
Are test certificates supplied with domestic orders?
Yes. Each size is supplied with its mill test certificate.
Can you quote against a drawing?
Yes. Send the drawing or specification and the material will be offered to match it.
What condition is supplied if I do not specify one?
Always state the condition. If it is omitted you will be asked, because strength varies widely between conditions.
Is heavy-wall 4130 tube available for machined parts?
Yes. Give the finished OD, bore and length so a suitable size can be offered.
Can hardness testing be added to an order?
Yes. Specify the hardness range or test required.
