5 Things to Know Before Buying 1.2312 steel

What is 1. steel?1. steel is a kind of hard plastic model steel with high abrasion resistance, high hardness and high hardness, and it has about 0.08% sulfur added on the basis of 1. steel, and it has excellent performance. It is used in many fields such as mold manufacturing, automated machinery and auto parts.

The main components of 1. materials include carbon, silicon, manganese, tungsten, molybdenum, chromium and vanadium and other elements. It is a chromium-nickel-molybdenum tool steel, in which the content of chromium and nickel is high, which improves the hardness and corrosion resistance of 1. steel, and a small amount of molybdenum is added to improve its strength and toughness. The ratio and content of these chemical elements affect the performance of 1. materials. For example, too high silicon content will also increase the brittleness and cracking tendency of 1., so the silicon content needs to be properly controlled.

Through technological breakthroughs, we have carried out a special pre-hardening production process on 1. steel, and its hardness can reach above 28HRC. Its machinability is best at 40HRC, and it can be used for advanced grinding. And its hardness after heat treatment can reach 50.7HRC.

(1) Mold Field steel can withstand high pressure and high temperature environment for a long time, and also has good corrosion resistance, which can prolong the service life of the mold. It is one of the best materials for making various molds, including making plastic molds, die-casting molds, metal Molds and injection molds, etc.

(2) Automotive Field In the automotive field, various auto parts need to have high strength, high hardness and high wear resistance to ensure the safety and stability of the car. 1. has these excellent properties and has become one of the important materials for the manufacture of auto parts. It mainly manufactures key components such as automobile bumpers, engine blocks, gears, automobile chassis, and clutch discs.

Plastic Mold Steels Comparison: 1. vs 1. vs 1.

As representatives of pre-hardened plastic mold steel, we will conduct a comprehensive comparison of 1. steel, 1. steel and 1. steel in terms of chemical composition, mechanical properties, heat treatment process, processing performance, application areas, etc. The following is their precise comparative analysis based on the latest revised composition data and performance characteristics:

1. Chemical Composition Comparison

GradeCCrMnMoS 1..35-0.451.8-2.11.3-1.60.15-0.25&#;0.03 1..35-0.451.8-2.11.4-1.60.15-0.250.05-0.1 1..35-0.451.8-2.11.3-1.60.2-0.4&#;0.035

Key summary:
&#; 1. and 1.: The composition is almost the same, 1. has a slightly higher sulfur content (better machinability), and both do not contain nickel.
&#; 1.: Unique nickel (Ni) and higher molybdenum (Mo), and extremely low sulfur, suitable for high polishing and high hardenability requirements.

2. Mechanical Properties Comparison

GradePre-hardening hardness (HRC)Tensile strength (MPa)ToughnessHardenabilityPolishability 1.--MediumGeneralGood 1.--MediumGeneralExcellent(sulfur microspheroidization) 1.--HighExcellent (for thick sections)Excellent (low sulfur) Performance analysis: &#; 1./1.: Similar hardness, 1. has slightly better polishing performance due to more uniform sulfur distribution, but no significant difference in toughness. &#; 1.: High nickel-molybdenum significantly improves hardenability and toughness, and low sulfur ensures that polishing can achieve a mirror effect (Ra < 0.01μm).

3. Comparison of Processing Characteristics

Characteristics1.1.1.

4. Application Field Comparison

GradeTypical application scenariosIndustry cases 1.Highly overlapped with 1., more suitable for mass production requiring fast cutting (such as multi-cavity molds)Consumer electronics accessories, plastic containers 1.Medium (preheating required)Medium (preheating required) 1.Large and complex molds, high-finish parts (such as automotive interior and exterior decoration, optical lenses), scenarios requiring high dimensional stabilityAutomotive bumpers, medical instruments, camera lens molds

5. Selection Recommendations

• 1.:
  &#; Advantages: low cost, easy processing, suitable for short-term projects or small batch production.
  &#; Limitations: general toughness, not suitable for high impact or high precision polishing requirements.
• 1.:
  &#; Advantages: high surface finish, suitable for transparent parts and optical products.
  &#; Limitations: slightly lower tensile strength, not suitable for ultra-high load scenarios.
• 1.:
  &#; Advantages: excellent hardenability, suitable for large molds and complex structures, strong long-term stability.
  &#; Limitations: high cost, difficult processing, professional heat treatment support required.

6. Common Misunderstandings Clarified

• Myth 1: 1. contains nickel &#; Wrong! Both 1. and 1. do not contain nickel, the only difference is the sulfur content.
• Myth 2: 1. has poor polishability &#; Wrong! Its low sulfur and high purity can achieve top polishing effects.

7. Summary

• 1.: Economical and practical, suitable for conventional plastic molds.
• 1.: Cutting efficiency is prioritized, suitable for rapid production.
• 1.: High-end and versatile, designed for large and high-demand molds.

Choose according to specific needs (size, surface requirements, budget). If you have further questions (such as heat treatment details), please continue to discuss!
