Pros

• Excellent Strength and Wear Resistance: S136 excels in applications requiring high strength and resistance to wear and tear.
• Good Corrosion Resistance: S136 offers good resistance to mild corrosion, making it suitable for various environments.
• Formability: Compared to some other high-strength PM steels, S136 exhibits good formability, allowing for more intricate shapes.
• Sinterability: S136 readily achieves high density during the sintering process, leading to strong and reliable PM parts.

Cons

• Cost: Compared to some more common PM steels, S136 can be slightly more expensive due to its specific alloying elements.
• Machinability: S136 can be somewhat challenging to machine due to its high hardness. Post-processing techniques like grinding or polishing may be necessary.
• Limited High-Temperature Performance: While offering good overall properties, S136 might not be the best choice for applications requiring extreme high-temperature performance.

Making the Choice: When to Consider S136

S136 is an excellent choice for PM applications where the following factors are crucial:

• High Strength and Wear Resistance: If your application demands components that can withstand significant wear and tear, S136 is a strong contender.
• Moderate Corrosion Resistance: For environments with mild corrosive elements, S136 provides adequate protection.
• Formability: If your PM parts require complex shapes, S136’s good formability offers design flexibility.
• Sinterability: When achieving high density in the final PM part is a priority, S136’s sinterability is a significant advantage.

Remember, the ideal PM material selection depends on the specific needs of your project. Consider factors like required mechanical properties, environmental exposure, cost constraints, and desired part complexity before making a decision.

FAQ

Q: How does S136 compare to other stainless steel powders for PM?

A: Compared to standard 300 series stainless steel powders, S136 offers superior strength and wear resistance. However, 316L stainless steel powder boasts better overall corrosion resistance. When both strength and corrosion resistance are crucial, some manufacturers offer high-nitrogen versions of 316L that offer a balance of these properties.

Q: Can S136 be heat treated for further improvement in properties?

A: Yes, S136 can be heat treated to achieve even higher hardness and wear resistance. However, this can come at the expense of some ductility and toughness.

Q: Are there any safety considerations when handling S136 powder?

A: S136 powder, like most metal powders, can be a respiratory irritant. Proper personal protective equipment (PPE) like dust masks and gloves are recommended when handling S136 powder. Additionally, proper ventilation and housekeeping practices are essential to minimize dust exposure.

Conclusion

S136 steel powder stands as a valuable asset within the PM toolbox. Its combination of strength, wear resistance, formability, and good corrosion resistance makes it suitable for a wide range of applications. By understanding its properties, limitations, and comparing it to other PM materials, you can make an informed decision on whether S136 is the right choice for your next PM project.
