DG60

DG60 non-magnetic steel, also known as DG60 non-magnetic hard alloy steel, is a type of high-hardness non-magnetic mold steel. This steel can be directly quenched after carburization, offering advantages such as high production efficiency, low cost, and minimal oxidation and decarburization. However, due to its high hardness, it has relatively poor toughness. The as-delivered hardness of DG60 is 55-60 HRC.

DG60 non-magnetic steel has a high hardness of HRC 57-61.

Q: What material is DG60? Performance introduction.

A: DG60 non-magnetic steel. This steel maintains a stable austenitic structure under various conditions, with very low magnetic permeability, high hardness and strength, and relatively good wear resistance.
Q: What is the difference between DG60 and imported HPM75?
A: HPM75 and DG60 differ in hardness;
Q: What is the as-delivered HRC hardness of DG60?
A: As-delivered hardness is HRC 57-61;
Q: What is the chemical composition of DG60?
A: Reference: Ni 55, Cr 45, with the remainder being rare earth elements. Tested hardness ranges from 57 to 61, grain size is grade 5, bending strength is 716 kg, impact toughness is 1.05 KG-M, and magnetic permeability is 1.0001.
Q: What is DG60 non-magnetic steel used for?
A: DG60 is suitable for manufacturing non-magnetic molds, non-magnetic bearings, and other structural components that require no magnetic induction in strong magnetic fields.
Q: Is DG60 the same as stainless steel 304?
A: DG60 is a non-magnetic mold material, while 304 is a genuine stainless steel series;
Q: What is the price of DG60?
A: DG60 non-magnetic steel is divided into two types: raw material and processed material (after solution treatment). Some unscrupulous manufacturers use stainless steel as a substitute, leading many companies to purchase materials in two batches, increasing original costs.
Q: What is the heat treatment method for DG60 non-magnetic steel?
A: DG60 has already undergone hardness treatment upon delivery.
DG60 is a high-hardness non-magnetic mold steel, also known as non-magnetic hard alloy steel; its as-delivered hardness is HRC 58-62. DG60 non-magnetic hard alloy and non-magnetic steel (7Mn15Cr2Al3V2WMo, hereinafter referred to as 7Mn15Cr2Al3V2WMo). Non-magnetic hard alloy offers good wear resistance but has a long production cycle and high mold processing costs, making it suitable for long-term products. 7Mn15 non-magnetic steel has lower wear resistance, a shorter mold manufacturing cycle, and lower costs, making it suitable for products with limited production volumes and short cycle requirements. The application range of DG60 non-magnetic steel is relatively narrow, and its heat treatment and processing工藝流程 as a mold are not widely understood.
DG60 (1) Direct Quenching: Direct quenching after carburization offers high production efficiency, low cost, and minimal oxidation and decarburization. However, due to the high carburization temperature, austenite grains grow, resulting in coarse martensite and more retained austenite after quenching, leading to poorer wear resistance and toughness. It is only suitable for fine-grained steels and parts with low wear resistance or low load-bearing requirements.
DG60 (2) Single Quenching: After slow cooling from carburization, the steel is reheated above the critical temperature, held, and then quenched. Compared to direct quenching, single quenching can refine the steel's structure to some extent. When high core structure requirements exist, the single quenching temperature is slightly above Ac3. For parts requiring high surface wear resistance and hardness but low load-bearing, the quenching temperature should be 30°C–50°C above Ac1 to refine surface grains while leaving the core structure largely unchanged, resulting in slightly lower performance.
DG60 (3) Double Quenching: For parts requiring high mechanical properties or coarse-grained steels, double quenching should be used. The first quenching aims to improve the core structure, with a heating temperature 30°C–50°C above Ac3. The second quenching aims to refine the surface structure, obtaining fine martensite and uniformly distributed granular secondary carbides, with a heating temperature 30°C–50°C above Ac1. DG60 is a high-hardness non-magnetic mold steel, also known as non-magnetic hard alloy steel; its as-delivered hardness is HRC 58-62. Austenitic non-magnetic steels are divided into non-magnetic high-manganese structural steels and non-magnetic stainless steels. Non-magnetic high-manganese structural steels are mainly used in civil fields such as power, transportation, and construction, while non-magnetic stainless steels are primarily used in high-tech fields like national defense and military industries. This analysis covers the domestic and international development and research overview of Fe-Mn series, Fe-Mn-Cr series, and Fe-Mn-Al series non-magnetic high-manganese structural steels, as well as non-magnetic stainless steels. It proposes China's development strategy for creating reduced-resource high-manganese non-magnetic steels that save on metals like Ni, Mo, and Cr, and high-end non-magnetic stainless steels. This approach meets both the mechanical and non-magnetic performance needs of civil applications and the comprehensive performance requirements of national defense and military applications, such as good mechanical properties, weldability, and corrosion resistance.
