ASTM A789/A790 Duplex Pipes, Tubes Kuwait

An ISO 9001:2008 Certified Company, Steelmet Industries (Pipe & Tubes Division) is one of the leading stockholder and supplier of ASTM A554 welded stainless steel tubing for mechanical applications where appearance, mechanical properties, or corrosion resistance is needed in a number of standard sizes and grades. Our stock of stainless steel polished/non polished welded tubes primarily consist of the austenitic grades of stainless steel including 201, 202 (4% Ni), 304, 304L, 316, 316L, in annealed and pickled, 2B finish, bright annealed, mill finish and polished conditions.

Alloy 2205 (UNS S31803) is one of the most recognized and widely used duplex stainless steel grade, with excellent general corrosion resistance and superiority over grade 304 or 316 in most environments. Steelmet Industries is India’s one of the most trusted supplier of various grades of duplex stainless steels including UNS 31803 (F51) and UNS 32205 (F60) Alloy 2205. The ratio of ferrite to austenite in Duplex stainless steel is approximately 50:50.

The characteristic feature of duplex stainless steels is their dual phase microstructure, comprising of approximately 50% of austenitic and 50% of ferrite. The yield strength of duplex stainless steel is typically double that of austenitic stainless steel.

Duplex fittings, duplex pipes and duplex plates are one of the key product items of Steelmet and are widely supplied from stock to various industries such as chemical, petrochemical, marine, oil and gas and transportation. Stainless steel Duplex pipes, Duplex tubing’s and Duplex fittings are widely used for oil field piping works and heat exchangers.

Duplex stainless steel pipes and fittings are considered as a cost effective grade due to lower nickel and molybdenum contents than their austenitic counterparts of similar corrosion resistance. Due to the lower alloying content, duplex stainless steels are generally lower in cost. Also, due to higher yield strength it could also be possible to reduce the thickness of duplex stainless steel products, compared to austenitic stainless steel. The dual benefit of lower prices and weight savings make duplex stainless steels economically very effective for project managers.

When compared to 2205 grade duplex stainless steel, 904L has similar corrosion resistant properties but lower mechanical strength. 2205 is also a lower cost option compared to 904L, but is not suitable for temperatures above 300°C. Grade 2205 is not generally suitable for use at temperatures above 300°C as it suffers from precipitation of brittle micro-constituents, nor below -50°C because of its ductile-to-brittle-transition.
