Heat Treatment Annealing Heat to 800 oC - 850 C, hold until temperature is uniform throughout the section and cool in furnace. Flame or Induction Hardening 4140 hardened and tempered bar can be further surface hardened by either the flame or induction hardening methods
4140 Steel Bar AISI A29 1.7225 42CrMo4 SCM440 - Otai AISI 4140 steel bar is widely used as tool steel in industrial applications. And we are professional astm 4140 steel alloy supplier, stockist and exporter.
42CrMo4 - Ovako42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening.
42CrMo4, 1.7225, 42CrMoS4, 1.7227, AISI 4140 description Structural steel, strong and hardenable. With this steel one can achieve very good properties on the whole cross-section (while quenching in oil, the max diameter is 70mm, for quenching in water it is 50mm).

Dear Sir, My query is about qualifying a procedure for the combination, EN19 (AISI 4140) to Weldox (S690QL) As youve stated in this article, qualifying 4140 in annealed condition is easier and S690QL properties will deteriorate on PWHT, What would be the heat treatment condition for the both materials then prior to qualifiaction to avoid PWHTAISI 4140 steel 1.7225 42CrMo4 SCM440 - OTAI Special 7. Heat Treatment of SAE/AISI 4140 Alloy Steel / 42CrMo4 steel. 4140 Steel Annealing; Slowly heat to 8008500 ºC, keep enough time, ensure heat thoroughly. then cooling in furnace to 480 ºC, then cool in air. After annealing, the hardness 92 HBS Max. AISI 4140 Steel Hardening & Quenching; 4140 Steel is usually used at 18-22 HRc, If needs, AISI 4140 alloy steel can be hardened or Quenching by cold work.
