Common specifications of Steel SA514 Gr Q Plate

Over the years, the company has established a standard of Steel SA514 Gr Q Plate steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to Steel SA514 Gr Q Plate quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

20Mn2 steel is used to manufacture carburized parts with low requirements on the surface and core, and with a cross-sectional diameter of less than 50mm, such as carburized pinions, small shafts, and low-demand pistons instead of 20Cr steel in the manufacture of automobiles, tractors and machine tools Pins, cross pin heads, diesel engine sleeves, valve jacks, gearbox levers, steel sleeves, etc. In addition, this kind of steel can also be used to make riveting weldments, screws, nuts, etc. under hot rolling and normalizing conditions.

The wear-resistant plate Steel SA514 Gr Q Plate shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and Steel SA514 Gr Q Plate hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

As the thickness and hardness of Steel SA514 Gr Q Plate increase, the tendency to crack at the cutting edge increases. In order to prevent the Steel SA514 Gr Q Plate from cutting cracks, preheating should be carried out before Steel SA514 Gr Q Plate cutting. Special attention should be paid to preheating to make the entire Steel SA514 Gr Q Plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole Steel SA514 Gr Q Plate cannot be preheated, the partial preheating method can be used instead.
