20Mn钢板化学成分和机械性能解析舞阳钢板20Mn保性能

1、20Mn钢板材料名称:20Mn碳素结构钢。

2、20Mn钢板执行标准：GB/T699-1999，20Mn钢板化学成分和机械性能解析|舞阳钢板20Mn保性能，20Mn钢板化学成分和机械性能解析|舞阳钢板20Mn保性能

3、20Mn钢板特性及适用范围：高锰低碳渗透钢，性能与15Mn钢相似，20Mn强度和淬透性比15Mn钢略高，其他性能与15Mn相近。应用与15Mn基本相同。

含锰（W mn 0.70%-1.00%）较高的低碳渗碳钢，因锰高故其 强度.塑性.可切削性和淬透性均比15钢稍高，渗碳与淬火时表面形成软点较少，宜进行渗碳.碳氮共渗处理，得到表面耐磨而心部韧性好的综合性能。热轧或正火处理后韧性好。

4、20Mn钢板热处理规范：正火,910℃。

1. 20Mn steel plate Material name :20Mn high quality carbon structural steel.

2. Standard of 20Mn steel plate: GB/T699-1999

3. Characteristics and application range of 20Mn steel plate: high manganese and low carbon permeable steel with similar properties to 15Mn steel, with slightly higher strength and hardenability than 15Mn steel, and other properties similar to 15Mn steel.The application is basically the same as 15Mn.

Low carburized carbon steel with high mn content (W Mn 0.70%-1.00%) has high strength due to high mn content.Plastic. Machinability and hardenability are slightly higher than 15 steel, carburizing and quenching surface soft point less, it is appropriate for carburizing.Carbonitriding treatment, the surface wear - resistant and the core toughness of the composite properties.Good toughness after hot rolling or normalizing treatment.

4, 20Mn steel plate heat treatment specification: normalizing,910℃.

5. Delivery status of 20Mn steel plate:

Delivery without heat treatment or heat treatment (annealing, normalizing or tempering at high temperature).The delivery in the condition of heat treatment shall be indicated in the contract. If it is not indicated, the delivery shall be made without heat treatment.
