nm400 wear-resistant plate

Introduction to nm400 wear-resistant plate

Name: N stands for resistance (nai) and M stands for the first pinyin letter of the two Chinese characters for wear (mo). 400 represents the average Brinell of this steel plate. Hardness

Heat treatment: high temperature tempering, quenching + tempering (quenching and tempering)

Application: NM400 wear-resistant steel plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery, etc. , also commonly used as high-strength structural steel with yield strength ≥800MPa.

Function: Mainly to provide protection in occasions or parts that require wear resistance, so as to extend the life of the equipment, reduce maintenance downtime caused by maintenance, and correspondingly reduce capital investment.

Performance: Yield is over 900, tensile strength is over 1100.

Production process flow

90-ton ultra-high power electric furnace smelting → LF refining → VD vacuum treatment → mold casting → steel ingot cleaning and heating → billet opening → billet cleaning → billet → heating → 4200mm rolled plate → heat treatment → inspection and storage.
