Overview

Stainless Steel Tube for Boiler is a seamless steel tube with open ends and a hollow section, the length of which is greater than the perimeter. It is mainly made of stainless steel, but the material can be selected on request. Stainless Steel Tube for Boiler is mainly used for the manufacture of water-cooled wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, etc. The Stainless Steel Tube for Boiler is available in a variety of lengths and sizes to meet various requirements.

Stainless Steel Tube for Boiler is an environmentally friendly and safe process. In addition, it has good resistance to corrosion and high temperatures, so it can be used for a long time. Our tubes are produced with high precision, uniform wall thickness, high brightness and can be made to measure according to customer requirements. It has good connectivity and is easy to install.

Chemical Composition

This table list material from N8810/800H to TP444/S44400. Other material compositions would be listed in other products.

Product Analysis:

An analysis of either one billet or one tube shall be made from each heat. The chemical composition thus determined shall conform to the requirements specified. 7.2.2 If the original test for product analysis fails, retests of two additional billets or tubes shall be made. Both retests, for the elements in question, shall meet the requirements of the specification; otherwise, all remaining material in the heat shall be rejected or, at the option of the producer, each billet may be individually tested for acceptance. Billets that do not meet the requirements of the specification shall be rejected.

Grain size shall be as given in Table 3, as determined in accordance with Test Methods E112. 8.2 Grain size determinations, to demonstrate compliance with 8.1, shall be made on one end of one finished tube from each lot..

Subsequent to the solution anneal required in Section 6, Grades TP309HCb, TP310HCb, TP310HCbN, TP321, TP321H, TP347, TP347H, TP348, and TP348H shall be given a stabilization heat treatment at a temperature lower than that used for the initial solution annealing heat treatment. The temperature of stabilization heat treatment shall be at a temperature as agreed upon between the purchaser and vendor.
