Product Description

YMT2344ESR

YMT2344 ESR chromium tool steel with reinforced alloying elements molybdenum and vanadium. The chromium element makes alloy steel resistant to softening at higher temperatures is a primary hardened steel with high temperature tempering resistance, maintaining high hardness and strength in high temperature environments. It has good performance in thermal fatigue resistance, corrosion resistance and wear resistance, and is a material with high toughness, high ductility and high hardenability. It can be directly water- cooled during production and use.

Chemical Composition:

Steel grade (%)	C	Si	Mn	Cr	Mo	V
YMT 2343ESR	~0.39	~1.05	~0.40	~5.20	~1.45	~1.00

Features:
Hot work alloy tool steels contain reinforced alloying elements molybdenum and vanadium
High toughness and hardness
Secondary hardened steel with softening resistance at high temperature and high temperature tempering property
High hardness and high strength in high temperature environment, good heat resistance, corrosion resistance and wear resistance.

Main Applications:
YMT2344 ESR is used in various hot-work molds, such as warm extrusion molds, light alloy die-casting molds and light/heavy metal hot forging dies and their accessories. For higher requirements, we recommend using electroslag remelted YMT2344ESR
