One of the most popular brands of chromium-Nickel structural steels — steel 20KHN3A — made in Russia and the CIS countries, accordingly to the technical norms and requirements of GOST 4543. The chemical composition was the following:
|The percentage of steel||0,17 0,24…||0,17…0,37||0,30…0,60||0,60…0,90||2,75 3,15…|
GOST permits the presence in the steel and metallurgical impurities such as phosphorus and sulfur. Their content in the finished product should not be higher than 0,025%.
A number of well-known foreign analogues of steel 20KHN3A. In particular, the steel brand is made 20hn3a Polish steel companies, and its composition fully corresponds to the grade 20KHN3A. Also known AISI 4320 steel which is smelted in the United States according to the norms of ASTM A569. The composition of the steel is given below:
|The percentage of steel||0,17 0,22…||0,15 0,30…||0,65 0,45…||0,40…0,60||1,65 2,00…||0,20…0,30|
ASTM A569 establishes that the tolerances on limit phosphorus and sulfur content must not exceed respectively 0,035% to 0,040%.

Properties and applications
Steel 20KHN3A, 20hn3a and AISI 4320 have a good workability in cutting and in all operations of cold stamping. Steel characterized by high strength, lend themselves well to all operations of heat treatment welded. Of the considered steels produce critical products of General machine-building purpose — flat levers, housing large tanks operating at elevated pressures, and high resistance fasteners.
After annealing of steel are characterized by the following physical-mechanical parameters:
- Limit strength is 580 MPa;
- Yield — 425 MPa.
- Young’s Modulus — 190…210 GPa;
- Elongation — 29%;
- The relative narrowing of the cross section — 58%;
- Hardness Brinell hardness — not exceeding 165 HB.
