EN 10294-2 is a European standard that specifies the requirements for hollow round bars made of stainless steel, particularly for use in machining applications. This standard covers various grades of stainless steel, each with unique properties and applications.
The hollow round bars specified under EN 10294-2 are primarily made from austenitic stainless steel grades, which are known for their excellent corrosion resistance, good mechanical properties, and ease of fabrication.
The specification includes dimensions, tolerances, and mechanical properties of the hollow round bars. These bars are typically used in the production of machined components, where strength and corrosion resistance are critical.

A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
