Buy at an affordable price a circle, wire or pipe, which are made of duplex stainless steel grade 1.4362 (S32304), offers KMZ. The enterprise guarantees timely delivery of products to any address specified by the consumer.

Composition and application

Stainless steel grade 1.4362 (S32304), or, otherwise, Duplex 2304 is a duplex stainless steel, with an optimum balance of ferrite and austenite. Steel has a high corrosion resistance, superior to that of related types of stainless steels, while its yield strength is almost twice that of austenitic stainless steels.

Due to the duplex microstructure, low nickel content and increased chromium content, 1.4362 (S32304) steel shows improved corrosion resistance. Steel can be used for the manufacture of products whose operating temperature ranges from -50 ° C to 300 ° C, and which require high mechanical strength, good weldability, high corrosion resistance (including stress corrosion cracking resistance), good mechanical machinability, low thermal expansion, good fatigue strength, high thermal conductivity, and increased plasticity during shaping.

The use of steel 1.4362 (S32304) is advisable in the production of welded pipeline systems in the pulp and paper, chemical and petrochemical industries, as well as in the manufacture of heat exchange pipes, pressure vessels, parts of food production equipment.

The chemical composition of steel:

Element Content in steel,%
Iron, Fe 72.679
Chrome, Cr 23
Nickel, Ni 4
Molybdenum, Mo 0.2
Bound nitrogen, N 0.1
Carbon, C 0.02

An insignificant (up to 0.001%) sulfur content is allowed.

To buy at an economical price from the manufacturer low-alloy duplex steel grades 1.4362 (S32304), or, otherwise — Duplex 2304 offers CMZ. The enterprise ensures the immediate shipment of products — pipes, wheels, wires — to any point agreed by the client.
