C45 steel heat treatment: Quenching has low hardenability, and it is easy to cause uneven hardness of the drill rod during heat treatment, resulting in deformation or even cracking. The hardness after quenching is about 42 degrees, which is much lower than the 55 degrees of 42CrMo brazing rod. Therefore, the wear resistance is extremely poor. Due to its low price, the A709 grade 50 high strength steel materials are produced in many places. Therefore, some manufacturers choose when manufacturing low-cost drill rods.
EN10083-3 27MnCrB5-2 steel plates have high requirement for technical strength of the steel mill. Therefore, A709 grade 50 high strength steel, EN10083-3 27MnCrB5-2 steel plates suppliers are limited and 27MnCrB5-2 steel plates price is not that cheap. Please contact BBN steel and so on reliable EN10083-3 27MnCrB5-2 steel plates suppliers to book quality guaranteed EN10083-3 27MnCrB5-2 steel plates.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A709 grade 50 high strength steel plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
