DETAILED INFORMATION
We have been serving our clients with premium quality Alloy 31 Buttweld Fittings for many decades as a trusted supplier.
This fastener has a nickel content of less than half of its total alloy content, but it is extremely austenitic due to its abundance of iron. It is a nickel-iron-chromium austenitic alloy. Despite being exposed to water, air, and alkali conditions, these fittings are extremely corrosion-resistant. They can withstand the aftereffects of sulfuric acid, even after they have been exposed to it for a short period of time. As far as potency is concerned, these are no different from the bases.
It is common to find these fittings in chemical mixers and fertilizer manufacturing equipment because they contain nickel, making them lightweight and shiny. Heavy industries including chemical processing and power generation use these fittings regularly. These fittings are suitable for marine applications because they resist corrosion of all kinds. It can also save you money compared to fittings made from other alloys due to its dimensional accuracy and ability to transport over long distances.
Due to their nickel, chrome, molybdenum, and copper compositions, these fittings are highly corrosion resistant, making them popular in this category. Despite its low carbon content, it can be welded and fabricated in corrosive environments without being heat treated after welding. The nickel content prevents stress corrosion cracking caused by chloride in these fittings. SCC problems are not common in these fittings, as with other alloys. Due to their ability to withstand unconditional changes in temperature, they can be kept at extreme temperatures and retain most of their properties. As well as desulfurization and pharmaceutical production, they are commonly used in chemical processing, dye production, and food processing plants.

Applications of Alloy 31 Butt weld Fittings
Typical fields of application for Alloy 31 Butt weld Fittings 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-
We ensure that all of our materials undergo rigorous quality control during the manufacturing process at Mehta Metals.com. There are many ways to test sheets and plates, including spectroscopy, positive material identification, mechanical testing, tensile testing, micro- and macro-testing, pitting resistance testing, and flaring testing. A three-part special test is performed: 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. Besides heart treatment charts and test certificates, we also offer welding procedure specifications, quality assurance plans, and fumigation certificates as value-added services.
