When it comes to crafting durable and efficient brick molds for brick making machines, the choice of steel plays a pivotal role. The selection involves a careful consideration of factors such as material features, advantages, disadvantages, pricing, wear and tear resistance under hydraulic tonnage, and the composition of each steel type. In this comprehensive guide, we’ll delve into five primary types of steel commonly used in brick molds for Hydraulic Brick Making Machines: Plain Mild Steel, Oil Hardened Mild Steel, EN8 Steel, Stainless Steel and D2HCHC Steel. (Don’t Miss the Comparison Table at the end!)
Table of Contents
1. Plain Mild Steel:
Composition:
Plain Mild Steel is a foundational choice for brick molds, composed primarily of iron and carbon (0.05% to 0.15%). Its ease of machining and affordability make it a common starting point for less complex shapes.
Manufacturing Process:
Plain Mild Steel is typically produced through basic steel-making processes, with minimal alloying.
Characteristics:
While cost-effective, Plain Mild Steel has lower hardness and wear resistance, making it suitable for low-impact applications.
2. Oil Hardened Mild Steel:
Composition:
Oil Hardened Mild Steel contains iron, carbon (0.30% to 0.50%), and additional manganese and chromium for improved hardening.
Manufacturing Process:
This steel undergoes a hardening process involving heating and quenching in oil, enhancing its durability.
Characteristics:
Oil Hardened Mild Steel strikes a balance between cost and performance, offering improved hardness and wear resistance for medium-stress applications.
3. EN8 Steel:
Composition:
EN8 Steel is a medium-carbon steel with a composition including iron, carbon (0.35% to 0.45%), manganese, and small amounts of other alloying elements.
Manufacturing Process:
EN8 undergoes a standard process of hot rolling, forging, and heat treatment to achieve its desired properties.
Characteristics:
Offering a compromise between cost and performance, En8 provides improved strength and hardness compared to mild steels.
4. Stainless Steel:
Composition:
Stainless Steel includes iron, chromium (at least 10.5%), and nickel, with various grades offering different properties.
Manufacturing Process:
Stainless Steel is produced through precision processes, including melting, casting, hot rolling, and heat treatment.
Characteristics:
Known for its corrosion resistance, moderate hardness, and versatility, Stainless Steel is suitable for applications in corrosion-prone environments.
5. D2HCHC Steel:
Composition:
D2HCHC stands for “High Carbon High Chromium.” D2HCHC Steel consists of iron, carbon (1.40% to 1.60%), chromium (11.00% to 13.00%), and other alloying elements.
Manufacturing Process:
The manufacturing process involves precision heat treatment to achieve the desired hardness and toughness.
Characteristics:
At the pinnacle of performance, D2HCHC Steel offers excellent wear resistance and toughness, making it ideal for high-stress applications.
Comparative Analysis for Brick Molds Making:

Conclusion:
The choice of brick mold material for brick making machines is a nuanced decision that requires careful consideration of various factors. While each type of steel has its merits, understanding the wear and tear implications under hydraulic tonnage is crucial. D2HCHC Steel emerges as a robust choice, providing excellent wear resistance even in high-pressure scenarios. The optimal selection of die mold material ensures the longevity, efficiency, and overall success of hydraulic brick making machinery.
