NM500 Steel

Naming :N is the first pinyin letter of "resistant" in "wear-resistant".
M is the first pinyin letter for "wear" in "wear".
500 is the Brinell Hardness number HB value. (500 hardness value is a broad sense, the domestic NM500 hardness value is about 500.)
NM500 wear-resistant steel plate is widely used in engineering machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.

Product Introduction

NM500 Steel

NM500 manufacturing process

The manufacturing process of NM500 wear-resistant steel plate mainly includes smelting, continuous casting, hot rolling, tempering treatment, quenching, tempering, finishing and other links. The specific manufacturing process is as follows:

Prepare the ingredients: Prepare the ingredients according to the required ingredients and proportions.

Smelting: Using vacuum induction furnace or electroslag remelting furnace to smelt, remove impurities and gases, and improve the purity of steel.

Continuous casting: The molten steel obtained is injected into the continuous casting machine to obtain the required size of the billet.

Hot rolling: The billet is heated to the austenitic state and hot rolled to obtain the required thickness of the steel plate.

Tempering treatment: The steel plate is heated above the critical point for tempering treatment, refining the organization, and improving the strength and toughness of the material.

Quenching: the tempered steel plate is quenched to obtain the wear-resistant steel plate with the required hardness.

Tempering: tempering the quenched steel plate to eliminate internal stress and improve the stability and toughness of the material.

Finishing: The steel plate is finished to remove surface defects and oxide layers to ensure the surface quality of the steel plate.

Cutting: Cutting steel plates into parts of the desired size as needed.
