Performance analysis of 45Mn excellent carbon steel

Performance analysis of 45Mn excellent carbon steel
1. Introduction to 45Mn steel plate:
45Mn is a high-quality carbon steel with high manganese content, commonly known as manganese steel, with good mechanical properties and generally directly made as mechanical parts.
2. 45Mn steel plate implementation standard: GB/T 711 and WTB
3, 45Mn steel plate can be Manufacturer: Wugang, the thickness of the production is 8mm-400mm
4, 45Mn steel plate delivery status: hot rolled or heat treated (annealed, normalized or high temperature tempered) state of delivery. If the delivery is required in the state of heat treatment, it shall be indicated in the contract, and those who are not specified shall be delivered according to no heat treatment.
5. The size, shape, weight and allowable deviation of 45Mn steel plate The size, shape, weight and allowable deviation
of 45Mn steel plate shall be applied in accordance with the provisions of GB/T709.

Note:
(1): In order to improve the properties of steel, other trace alloying elements other than the above table can be added, and the data comes from the network and is for reference only.
(2): The allowable deviation of the chemical composition of the finished steel plate shall comply with the provisions of

GB/T222 45Mn steel plate smelting method: 45Mn steel is smelted by oxygen converter or electric furnace.
9. Ultrasonic testing of 45Mn steel plate After negotiation between the supply and demand parties, the steel plate can be ultrasonic tested according to GB/T2970, and the testing
standard and qualification level should be specified in the contract.
10. The main properties and application range
of 45Mn steel plate 45Mn medium carbon quenched and tempered steel, strength, toughness and hardenability are higher than that of No. 45 steel, after quenching and tempering treatment, good comprehensive mechanical properties can be obtained, and the cutting performance is good, but the welding performance is poor, the cold deformation plasticity is low, and there is a tendency to temper brittleness, which is generally used in the quenched and tempered state, and can also be used in the quenching and tempering or normalizing state. It is used in the manufacture of worn parts, such as rotating shafts, mandrels, crankshafts, spline shafts, connecting rods, universal joint shafts, meshing rods, gears, clutch discs, bolts, nuts, etc.
