Steels heavy section

Pigmented resins are applied as dry powders and then fused by heating to 220°C or higher. The process is effective with lightweight metal components and pipework. It is likely to remain uneconomic for use on heavy sections, e.g. hot-rolled steel universal beams and columns. 

One of the principal functions of alloying elements in steel, such as manganese, chromium, nickel, molybdenum, etc., is to increase the hardenabilitv. Whereas prodigious amounts of expensive alloys were formerly used to insure full hardening, especially in medium and heavy sections, wartime shortages focused attention on the use of as little alloy as possible within the hardenabilitv requirements. A large number of steels were developed containing relatively small additions of a number ol elements, and a number of these steels hav e continued in use. 

ASTM E185-82 also provides the option of including correlation monitor material in the capsules. Correlation monitor material provides an independent check on the irradiation conditions because other specimens of the same correlation monitor material have been irradiated in other reactors and its response to irradiation (embrittlement characteristics) is well documented. An example of a common correlation monitor is Heavy Section Steel Technology (HSST) Plate 02 (an SA533 Grade B, Class 1 material). Correlation monitor material is also included in the surveillance program to provide a means of validating neutron fluence estimates for the surveillance capsules. The data obtained from correlation monitors should...
