Q345R steel (16MnR) is a low-alloy high-strength steel. It is a special plate for pressure vessels with a yield strength of 340MPa min. Q345R plate has good comprehensive mechanical properties and technological properties. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 steel (16MnR). In addition to the increased tensile strength and elongation requirements compared to Q345B steel, 42CrMoS4 alloy steel material steel quality, the impact toughness is also required.
Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. 42CrMoS4 alloy steel material steel quality, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of 42CrMoS4 alloy steel material steel quality, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.
After extrusion, the 42CrMoS4 alloy steel material steel quality tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
42CrMoS4 alloy steel material steel quality, 27SiMn material has high strength and wear resistance, high hardenability, medium plasticity during cold deformation, good machinability and fair weldability. It is mostly used after quenching and tempering, and can also be used in normalizing or hot rolling state. 27SiMn material chemical elements: C: 0.24-0.32, Si: 1.10-1.40, Mn: 1.10-1.40. 27SiMn material mechanical properties: tensile strength 980 MPa; yield strength: 835 MPa; elongation after fracture: 12%; impact energy: 39J. 27SiMn material can be used to make hot stamping parts with high toughness and high wear resistance, which do not need heat treatment or normalizing, such as tractor track pins.
The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC 42CrMoS4 alloy steel material steel quality steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system. Sincerely welcome new and old customers to visit our company, BBBN company will always be your reliable choice.
