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 A514 Gr Q structural steel material materials are produced in many places. Therefore, some manufacturers choose when manufacturing low-cost drill rods.
In view of the characteristics of container transportation, such as high added value, low cargo damage and short time, our company takes more consideration of port collection and distribution conditions, port facilities, flight density and route coverage when choosing ports. For the convenience of customers, as well as the safety of goods.
On September 14th 2019, a Australia customer purchased 500 tonsDIN17155 15Mo3 boiler steel plates, which will be used for vessel modification of wax backflow protection project and LPU project. Many old customers keep asking about Din17155 steel grade-15Mo3. Usually our company would suggest customers to choose EN10028 steel specification, but if customer insiste on the old steel grade, we could arrange it either. With years of experience in produceing DIN 17155 15Mo3 boiler steel plates, the company supplies high quality steel A514 Gr Q structural steel material product with low cost and better service.
