High-carbon heavy-walled seamless black steel tube 159x30 is a massive industrial profile manufactured from premium Steel 45 (C45E). Produced by hot rolling solid cylindrical billets, it offers a monolithic structure without any weld seams, ensuring maximum structural integrity and mechanical resistance. With a 159 mm outer diameter and an extra-thick 30.0 mm wall, this pipe acts as an ideal nearly-solid starting material for components subject to extreme torque and wear.

The product is certified under EN 10216-1 for pressurized engineering systems and EN 10210-2 for load-bearing structural hollow sections (3.1 + CE certified). Steel 45 provides high surface hardness and tensile strength, which is vital for heavy-duty machine building. This pipe is frequently used to manufacture heavy rollers, geared rings, shafts, and bushings requiring deep precision machining. The seamless technology ensures that the material performs reliably during thermal cycles and heat treatments, preventing common issues like weld fatigue and longitudinal cracking.

The untreated black surface is suitable for specialized industrial coatings or further hardening processes. We offer self-pickup from logistics hubs in Europe, Poland, and Bulgaria. Wholesale terms are available for bulk orders starting from 1 ton. Our metal centers provide professional band-saw cutting for precise length requirements.
