GB/T 11251 20Cr hot rolled structure steel plates ,GB/T 11251 20Cr hot rolled structure steel plates are widely used to manufacture carburized parts (oil quenching) that have high requirements for core strength, bearing surface wear, section below 30mm, shape is complex and load is small. For example:machine transmission gear, gear shaft, cam, worm, piston pin, claw clutch.
GB/T 11251 30CrMnSiA hot rolled structure steel plates Product Description GB/T 11251 30CrMnSiA hot rolled structure steel plates are medium carbon tempered steel with high strength and poor welding performance. After quenching and tempering, 30CrMnSiA alloy steel plates have high strength and toughness and good hardenability.

Grade 20Cr Steel Composition, Properties, Material EquivalentCompared with 15Cr steel, 20Cr has higher strength and hardenability. The critical hardenable diameter in oil is 4-22mm, and the critical hardenable diameter in water is 11-40mm, but the toughness is poor. The machinability is good under high temperature normalizing or quenching and tempering conditions, but it is poor after annealing.
HT-Quench and Tempering - Industrial HeatingQuench and Tempering Tubular Products Donald H. Wiseman ABP Induction, Brook eld, Wis. With the cost of steel going up precipitously, methods of providing higher-strength, lower-weight designs have become keenly important. This scenario is very true in tubular goods.

IntroductionProcess StepsStress-Strain DiagramInfluence of Alloying Elements on Martensite FormationInfluence of The Alloying Elements on The Choice of Quenching MediumThe heat treatments explained in the chapter on annealing processesmainly related to the improvement of production-orientated properties such as formability, machinability, etc. In many cases, however, a high degree of hardness or strength is required. This can be seen, for example, in a file blade for processing workpieces. To ensure that the file removes the material from the workpiece and does not become blunt itself, it must be correspondingly wear-resistant and therefore very hard. Another example where high hQuench & Tempered Steel - Alloy Q&T Steel Bar Eaton What is quench and tempered steel? Quenching and tempering are processes that strengthen materials like steel and other iron-based alloys. These processes strengthen the alloys through heating the material while simultaneously cooling in water, oil, forced air, or gases such as nitrogen. Alloy Q&T Steel Bar Process
Steels for quenching and temperingSteel grades C35, C40, C45, C55 and C60 are classified according to EN 10020 as non alloy quality steels and the other steel grades as non alloy special steels. 4.2 Designation 4.2.1 Steel names For the steel grades covered by this document, the steel names as given in the relevant tables are allocated in accordance with EN 10027-1.
