PRODUCTS
Stainless Products supplies stainless steel seamless tube per ASTM A 213, ASTM A 269 and ASTM A 511. We supply common grades of stainless steel such as 304/304L and 316/316L in standard tube sizes and wall thicknesses. We can also supply nickel alloys.
Product Introduction
We also supply stainless steel hollow bar for machining applications with wall thicknesses in excess of 2″ for some stainless grades. Most sizes of seamless stainless steel and nickel tube can be cut to exact sizes. Non-standard sizes can be made to order. Contact a sales associate today for your exact seamless nickel or stainless steel tubing requirement.

Value-added Services
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.
Kuncheng 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.
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.
In some cases, it may be necessary to complete additional positive material identification testing. Kuncheng can complete this testing in house or we can work with an independent laboratory to complete the testing. Please contact us for specific requirements.
Tolerances
These tolerances apply to cut lengths up to an including 24 Ft. (7.3M). For lengths over 24Ft. an additional over tolerance of 1/8in (3.1mm) for each 10ft. (3m) or fraction thereof shall be permissible up to a maximum tolerance of 1/2 in. (12.7mm)
