UNS S31803/S32205

Description

Avesta Sheffield 2205 is a ferritic-austenitic stainless steel which combines many of the beneficial properties of both ferritic and austenitic steels. As a result of high chromium and molybdenum contents, the steel has very good pitting and uniform corrosion resistance to stress corrosion cracking as well as high mechanical strength.

2205 has good weldability and can be welded using most of the welding techniques for stainless steels. Due to the balanced composition, when welded correctly, the heat affected zone contains sufficient austenite to avoid the risk of localized corrosion. The chemical composition of 2205 is balanced to give a microstructure containing roughly equal amounts of ferrite and austenite.

UNS N08020

Description

A nickel-iron-chromium alloy with additions of molybdenum and copper. Alloy 20 has great resistance to pitting, general corrosion, and crevice corrosion in chemicals containing sulfuric, nitric, and phosphoric acids as well as chlorides. It also contains niobium for stabilization and is used for piping, tanks, pumps, valves, heat exchangers, and other process equipment.

UNS S30400/S30403

Description

304 stainless steel is a low carbon (0.08% max) version of basic 18-8 also known as 302. Type 302 has 18% chromium and 8% nickel. Type 304 has slightly lower strength than 302 due to its lower carbon content. Type 304 stainless steel finds extensive use in welding applications because the low carbon permits some exposure in the carbide precipitation range of 800 0 F – 1500 OF without the need for post-annealing operations. However, the severity of corrosive environments may necessitate annealing after welding or the use of 304L. Type 304L has a carbon content of 0.03% or less. This alloy can be used in the as-welded condition without becoming susceptible to intergranular corrosion.
