Alloy 31 is a hybrid of austenitic super stainless steels and nickel alloys, designated as UNS N08031 or DIN W.Nr. 1.4562 due to nitrogen and copper additions. It is classified as UNS N08031 or DIN W.Nr. 1.4562. In addition to alkaline and halide-containing media, sulfuric acid, phosphoric acid, chlorine dioxide, nitric acid, and reducing & oxidizing media, alloy 31 is exceptionally corrosion resistant. The material is widely used in offshore and marine industries, chemical & petrochemical processing, pharmaceutical piping, oil and gas extraction, and ore digestion plants. In particular, Alloy 31 can be used to manufacture pressure vessels that can endure temperatures ranging from cryogenic temperatures to elevated temperatures (-196°C to 550°C).

Applications of Alloy 31

Typical fields of application for Alloy 31 are:

  • Plant components for flue gas desulfurization (FGD)
  • The wet digestion process is used to produce phosphoric acid
  • Sulfuric acid pipes and heat exchangers contaminated with chlorides
  • Condensers, chillers, and pipes containing ocean and brackish water
  • A sulfuric acid pickling plant as well as a nitric-hydrofluoric acid pickling plant
  • Using waste sulfuric acids for treatment
  • Salt crystallization and evaporation
  • Components for the cellulose and paper industries
  • For the digestion of laterite ores, HIPAL (high-pressure acid leach) plants are used
  • Production and refinement of mineral oil
  • Synthesis of organic acids and esters
  • Chemicals of fine quality
  • Oil and gas transport pipes, slicklines, wirelines, and flowlines that are strain-hardened
  • Diesel scrubber for marine use / marine scrubber for ships
  • Tubes for waste to energy that are longitudinally welded

Test and test certificates-

During the manufacturing process, Mehta Metals.com ensures that all of our material is subjected to rigorous quality control before it is shipped. Spectro analysis, PMI or positive material identification, hardness testing, mechanical testing, tensile testing, micro- and macro-testing, pitting resistance testing, and flaring testing can all be used to test sheets and plates. There are three kinds of special tests: intergranular corrosion, flattening, and third-party inspection.

A manufacture test certificate is issued upon completion of the above-mentioned tests, including a thirst party inspection report, a 100% radiography report, a raw material certificate, and an EN 10204/3.1b certificate. In addition to heart treatment charts and test certificates, we also offer welding procedure specifications, quality assurance plans, and fumigation certificates as value-added services.

Alloy 31 Products Material Testing

We at Mehta Metals.cols go through strict quality tests before dispatching them to our clienm ensure that all our materiats.

  • Testing by mechanical means, such as tensile tests
  • Hardness Test
  • Chemical Analysis – Spectro Analysis
  • Testing for Positive Material Identification (PMI)
  • Flattening Test
  • Micro and MacroTest
  • Pitting Resistance Test
  • Flaring Test
  • Intergranular Corrosion (IGC) Test

Alloy 31 Products Documentation

  • HS Code included in a commercial invoice
  • An itemized packing list including net and gross weights, boxes, markings, and numbers
  • Obtain legalization/attestation by the Chamber of Commerce or the Embassy of the country of origin
  • Fumigation Certificates
  • Raw Material Test Reports
  • Material Traceability Records
  • Quality Assurance Plan (QAP)
  • Heat Treatment Charts
  • Certification certificates for NACE MR0175 and MR0103
  • As per EN 10204 3.1 and EN 10204 3, test certificates (MTCs) are required. Guarantee letters
  • NABL-approved Laboratory Test Reports
  • Specification for welding procedures and procedure qualification records, WPS/PQR
  • In accordance with the Generalized System of Preferences (GSP), Form A must be completed

Alloy 31 Products packaging-

As part of ensuring quality, the packaging unit, which includes pallets, wooden packs, and eco-friendly bags for sheets and plates, must be carefully considered.
