BEVELING
Beveling Stainless Steel tubes contain one end angled, so that it mates with a complementary tube end. Tubes can be beveled for certain applications in order to make welding of stainless steel tubes easier, which saves weld prep time and money compared to hand cutting.
HEAT TREATING & ANNEALING
Eastern Steel can heat treat some 400 series stainless steel seamless tube. Heat treating realizes stress as a result of hardening, depending upon the chemistry of the metal being treated. Heat treating is also used for tempering, quenching, normalizing, and solution annealing.
HONING & TURNING
During the honing/turning process, an abrasive rotating tool removes metal from the interior surface of a cylinder, pipe, or tube. The main purpose of honing is to finish the surface to a particular diameter and/or desired cylindrical geometric design. Honing is typically a secondary machining operation that completes a produce/part, relieves stress created during production, or corrects features of the finished product. A typical production cycle is to drill, ream, heat treat, then hone.
POLISHING
POSITIVE MATERIAL IDENTIFICATION (PMI)
In some cases, it may be necessary to complete additional positive material identification testing. Eastern Steel can complete this testing in house or we can work with an independent laboratory to complete the testing. Please contact us for specific requirements.
UT TESTING
Ultrasonic Testing (UT) utilizes sound energy at high frequencies, in order to provide examinations and measurements of the stainless steel product. This aids in flaw detection/evaluation, dimensional measurements, etc.
Product application areas
ss smls pipe

Stainless steel pipes are an indispensable component in a wide range of industries and applications due to their exceptional properties. Known for their corrosion resistance, durability, and versatility, stainless steel pipes are favored for transporting various fluids and gases, especially in environments where corrosion and chemical reactions are a concern. These pipes find extensive use in the construction of architectural structures, plumbing systems, and industrial facilities. Their strength, low maintenance requirements, and the ability to withstand extreme temperatures make them ideal for applications as diverse as conveying potable water, chemicals, and even in the food and pharmaceutical industries. The aesthetic appeal and ease of fabrication add to the appeal of stainless steel pipes, making them a crucial choice for projects where long-term performance and reliability are paramount.
