Composition of steel and its application

Stainless steel grade 1.4663 (S82441) or, otherwise, the LDX 2404® is a solid duplex stainless steel containing molybdenum in its composition. Steel LDX 2404® is designed with such a complex of properties to fill the gap between existing duplex steel grades LDX 2304 and LDX 2205. The steel in question is highly resistant to uniform corrosion, pitting corrosion and cracks, as well as to stress corrosion cracking caused by mechanochemical corrosion. Steel 1.4663 (S82441) is distinguished by good mechanical strength, resistance to abrasion and erosion, good fatigue strength and good weldability. High energy absorption and low thermal expansion are other positive features of this material.

Rational areas for the use of steels of these brands are devices and apparatuses of the energy and oil and gas industry, reservoirs and vessels under pressure, pipelines, boilers. Water heaters. Steel is also used in the construction of multi-storey buildings, as well as in technologies for purification and desalination of water.

The chemical composition of steel 1.4663 (S82441), which meets the technical requirements of SAE-AISI 4340M and UNS S82441:

Buy at an economical price circle, wire, a tube of duplex stainless steel 1.4663 (S82441) offers KMZ. The enterprise guarantees the prompt delivery of products to any point indicated by the customer.

Properties

The physical and mechanical characteristics of this steel are given below:

• The limit of temporary resistance, MPa — 550… 690 (determined by the range of delivery of metal);
• Yield strength, MPa — 400… 490 is determined by the range of delivery of metal);
• Relative elongation at tension,% — 200… 210;
• Impact strength, MJ / m ³ — 190;
• Hardness by Rockwell, HRC — 55;
• The coefficient of thermal conductivity in the temperature range 20… 400 ⁰ С, W / mK — 38.

Workability of steel

The stainless steel grade LDX 2404® can be quenched in the temperature range of 900… 1120 ° C (1652−2048 ° F), after which annealing is performed to restore the original properties. Weldability of steel — without restrictions. Steel 1.4663 (S82441) is well susceptible to plastic deformation in the cold state.

KMZ sells a pipe, circle or wire made of duplex stainless steel 1.4663 (S82441) at economically reasonable prices. Provides timely delivery of products to any point set by the customer.
