What are the common precision alloy steel materials in Dalian?
In modern industrial manufacturing, Dalian precision alloy steel has become an indispensable basic material for high-end equipment manufacturing due to its excellent mechanical properties, physical characteristics, and processing accuracy. According to different performance requirements, common precision alloy steel materials can be mainly divided into the following categories.
Bearing steel is a typical representative of precision alloy steel, mainly composed of high carbon chromium steel such as GCr15. It is characterized by high hardness, strong wear resistance, and excellent fatigue resistance, and is widely used in the manufacturing of various precision components such as bearings and balls. The high-purity smelting process ensures low impurity content, effectively improving the service life and operational stability of the parts.
Mold steel is also a commonly used precision alloy steel material, including cold work mold steel (such as Cr12MoV) and hot work mold steel (such as H13). Cold work mold steel has high hardness and good toughness, suitable for manufacturing stamping, cold heading and other molds; Hot work mold steel has good thermal fatigue resistance and high-temperature strength, and is commonly used in high-temperature forming molds such as die-casting and forging. It can maintain mold accuracy during repeated heating and cooling processes.

Martensitic stainless steel (such as 1Cr13) and precipitation hardening stainless steel (such as 0Cr17Ni4Cu4Nb) in Dalian precision alloy steel also belong to the category of precision alloy steel. Martensitic stainless steel combines high strength and corrosion resistance, and is commonly used in medical devices and aerospace components; Precipitation hardened stainless steel can achieve ultra-high strength and good plasticity through heat treatment, playing an important role in precision instruments and marine engineering fields.
In addition, high-speed steel (such as W18Cr4V) is known for its high hardness, wear resistance, and red hardness, and is a key material for manufacturing cutting tools. Even during high-temperature cutting, it can maintain a sharp edge, greatly improving machining efficiency and accuracy. These common precision alloy steel materials, with their unique performance advantages, jointly support the precision manufacturing needs of modern industry.
