Technical characteristics

The chemical composition of this grade of steel determines GOST 5632−72. The main additional components to the material based on iron are Nickel and chromium. Steel belongs to the austenitic class, and generally used for parts working in conditions of up to +700°C, in the manufacture of springs and mounting hardware. Marking of steel 10KH11N23T3MR interpreted as follows. 10 — carbon content of about 0.10 percent, X11 — chromium content of about 11%, Н23 — Nickel content 23%, T3 is about 3% titanium, M is about 1% molybdenum .

Alloying has a multifaceted effect on the quality of the steel. Chromium increases the hardness, corrosion resistance. The Nickel gives the alloy ductility; resistance to shock load. Molybdenum alloy imparts red-hardness, strength, opposition to oxidation at high temperature. The proportion of manganese is above 1% increases the hardness, toughness, durability. Titanium increases the stability, corrosion resistance. This steel is characterized by:

  • satisfactory weldability;
  • good machinability;
  • elongation — up to 10%.


As the filler metal used welding wire SV-10Х16Н25АМ6 SV-08Х15Н23В7Г7М2. Sheet thickness of 10 mm welded manual arc welding satisfactorily. TIG method is recommended for welding of sheets less than 6 mm thick and the root joints over 10 mm. Preferably the steel is welding with stainless brands such as 07KH16N6, 12X18H10T, 12H21N5T, and high-temperature KHN60VT and ХН77Т1О. For welding with Nickel heat resistant alloys recommended welding wire Св06Х15Н60М15 with stainless steel alloys — SV-04Х19Н11МЗ.
