KMZ sells wire, circle and pipe, which are manufactured from stainless steel grade 10Х11Н23Т3МР (ЭП 33) at reasonable prices from the manufacturer. The enterprise guarantees the prompt dispatch of products to any point indicated by the consumer.

Composition and application

Stainless steel grade 10Х11Н23Т3МР (ЭП 33) refers to high-alloy heat-resistant steels, from which mainly fastening and normalized products working at elevated temperatures are manufactured. The material in question is austenitic grade steel and maintains its serviceability at external temperatures not exceeding 650… 700 0 С. Steel 10Х11Н23Т3МР (ЭП 33) is not recommended for use in welded constructions, because in most welding technologies the strength of the weld does not reach the strength of the main welded details. It is allowed to use this steel when manufacturing turbine disks and blades. The most high-quality steel is 10Х11Н23Т3МР-ВД, which is produced by vacuum arc technology.

The chemical composition of steel grade 10Х11Н23Т3МР (ЭП 33), which meets the technical requirements of GOST5632−80, is presented in the table:

Chemical element Content in percent
Carbon ©, not higher 0.1
Silicon (Si), not higher 0.6
Copper (Cu), not higher 0.3
Tungsten (W), not higher 0.2
Manganese (Mn), not higher 0.6
Nickel (Ni) 21.00… 25.00
Phosphorus (P), up to 0.025
Chrome (Cr) 10.0… 12.5
Sulfur (S), up to 0.01
Vanadium (V), not higher 0.2
Molybdenum (Mo) 1.00… 1.60
Titanium (Ti) 2.8… 3.2
Boron (B), not higher 0.02
Aluminum (Al), not higher 0.8

Note: Boron is introduced into the composition of steel in quantities determined by calculation.

To buy heat-resistant stainless steel grade 10Х11Н23Т3МР (ЭП 33) in a wide range of profiles (circle, pipe, wire) and at affordable prices the manufacturer offers КМЗ. The enterprise ensures timely shipment of products to any point specified by the customer.
