Chemical composition
30ХН3А steel grade is one of chromium-nickel constructional steels produced in CIS countries in accordance with
| Chemical element | С | Si | Mn | Cr | Ni |
|---|---|---|---|---|---|
| Presence in steel, % | 0,27...0,33 | 0,17...0,37 | 0,30...0,60 | 0,60...0,90 | 2,75...3,15 |
In addition, in the composition of this steel there are nonmetallic impurities - sulfur and phosphorus. Their percentage in the finished product should not exceed 0.03%.
Of the nearest European analogues of this steel, steel grade 31NiCr14 (1.5755) should be mentioned. This steel is melted according to the standards AISI A518 and DIN C50. The chemical composition of steel 31NiCr14 (1.5755) is as follows:

The supplier guarantees strict adherence to the assortment of rolled steel products supplied, and ensures their timely transportation to the location specified by the customer.
Properties and application
Structural alloyed steel of the considered grades is widely used for manufacturing of the enclosing structures, tanks of vessels working under increased pressure, as well as for cold and hot forging of high-strength fasteners. Steels 30KhN3A and 31NiCr14 (1.5755) are successfully amenable to hardening heat treatment and hot volume forging, machinability is reduced.
After quenching and subsequent tempering these grades of steel have these physical and mechanical properties:
- Tensile strength, MPa - 1000;
- Limit of plasticity - 800 MPa;
- Relative elongation - 9%;
- Relative narrowing of the cross section - 50%;
- Impact viscosity - 800 kJ/m2;
- Young's modulus - 210 GPa.
