Heat-Treatment Guidance (General)
Annealing/Softening: for machining readiness before hardening
Hardening (Quench): austenitize, then oil/air quench to develop martensite
Tempering: select temperature to balance hardness vs. toughness (e.g., ~200–300 °C for higher hardness; higher temp for more toughness)
| Brinell hardness for 30KH13 ( 30Х13 ) (quenching, tempering) , GOST 25054-81 | HB 10 -1 = 235 - 277 MPa |
| Brinell hardness for 30KH13 ( 30Х13 ) (annealing) , Bar GOST 5949-75 | HB 10 -1 = 131 - 207 MPa |
Technological properties for grade 30KH13 ( 30Х13 )
