Heat treatment technology of 15CrMoR steel gb713

15CrMoR steel gb713, 2.25Cr-1Mo steel, 2.25Cr means that the content of Cr is about 2.25%, 1Mo means that the content of Mo is about 1%. It is chromium molybdenum steel, low alloy high strength steel, and belongs to heat-resistant alloy steel, also known as SA387gr22cl2 or A387 gr22 cl2.2.25Cr-1Mo steel plate executive standard: the appearance is in accordance with the ASTM A20/A20M standard, and the internal is in accordance with the ASTM A387/A387M standard.

As soon as the grains of the steel sheet become coarse, the forming limit decreases. The total elongation, n value and r value in the mechanical properties of the 15CrMoR steel gb713 steel plate have no direct influence on the forming limit of spinning. The steel plate used in the test is very thin (about 0.5mm), and the commonly used thickness 15CrMoR steel gb713 steel plate (0.8-1.6mm) will definitely be much higher than the above limit.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and 15CrMoR steel gb713 pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the 15CrMoR steel gb713 project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of 15CrMoR steel gb713 customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
