UNS N08031 is an iron-nickel-chromium-molybdenum alloy with the addition of nitrogen.Alloy 31 has proven
itself to be suitable particularly in the chemical and petrochemical industries, in ore digestion plants, in environmental and marine engineering as well as in oil and gas extraction
The chemical composition of UNS N08031 forged material shall be made on samples which correspond to the top & bottom of the re -molten ingot used to the make the part according to ASTM E354, ASTM E1473, ASTM E2465 and ARP1313 for trace elements (lead, bismuth and selenium). Others than abovementioned standards may be used provided THAT they are approved by the purchaser.

For Every pieces of UNS N08031,Alloy 31 forging round bars, we could do following testing Non destructive tests such as visual, dimensional, ultrasonic testing,dye penetrant testing , Magnetic particle test(MPl), the mirrostructure and technological tests such as tensile, resilience, creep tests, hardness,Metallographic exams,Chemical analysis
Qualification of manufacturing procedure of UNS N08031,Alloy 31 forging parts
The Manufacturing Process Plan (MPP) shall be submitted to the approval of clients Material
& Process Engineering dept. clients before qualification procedure begins. It shall detail at least
the following:
• type of ingot (supplier, manufacturing process, dimensions, and tests to beperformed);
• forging process;
• heat treatment process;
• tests on component.
In general, dissection of the first piece within the terms detailed in the part specification is required.
This activity may be omitted, upon decision of clients, if the supplier has already proven to be able to successfully produce components of similar shape, dimensions and manufacturing
process.
