What Is EN 10296-2 1.4301 Tube?
The product is a welded circular stainless steel tube produced according to European technical delivery criteria for mechanical and general engineering needs. This standard differs from pressure bearing tubes to EN 10217-7 and emphasises the structural integrity, dimensional control and mechanical adaptability.
Equivalent to AISI 304 or X5CrNi18-10. 1.4301 steel is a stainless steel of the austenitic group with 17.5-19.5 % chromium and 8.0-10.5 % nickel. Excellent formability, weldability and corrosion resistance in different working situations are assured with this chemical composition.
The standard tackles important pain issues in the industry: ultra-precise tolerances for automated assembly lines, constant weld seam strength for structural loads, and removal of micro-fissures that cause premature failure in high-vibration gear. Your projects benefit from tubes developed for long term performance in demanding mechanical applications.
