- 27SiMn: Distinguished by its high strength and commendable mechanical properties, 27SiMn is frequently featured in specialized applications mandating robust performance under high impact and load.
- Stainless Steel:
- 304: Esteemed for its excellent corrosion resistance, this material is commonly applied in environments exposed to moisture or corrosive agents. It is apropos for applications in which the prevention of rust is imperative.
- 316: Offering enhanced corrosion resistance, notably against chlorides, stainless steel 316 is frequently utilized in marine or coastal environments where corrosion is a primary concern.
- Micro-Alloyed Steels:
- 20MnV6: A carbon-manganese steel alloyed with vanadium, 20MnV6 is tailored for super high-strength applications, delivering superb mechanical properties.
SAE 4140—How Does The Chemical Composition Affect Performance in High-Pressure Applications?
Is SAE 4140 the right choice for your high-pressure application? Explore how the chemical composition increases its performance.
SAE 4140 is an alloy steel containing chromium, molybdenum, and carbon. These elements give it exceptional tensile strength and yield strength, making it ideal for high-pressure hydraulic applications requiring strength and wear resistance. The addition of chromium provides excellent resistance to corrosion, while molybdenum adds toughness and impact resistance, making SAE 4140 an excellent choice for heavy-duty use in high-pressure applications.

Specific Applications for 27SiMn Honed Tubes
Can 27SiMn be the answer for you? Here are a few areas where you might prefer this material compared to others.
27SiMn is preferred in certain conditions where toughness and fatigue resistance are required. It is more commonly used in high-impact and high-load applications. Applications include but are not limited to:
- Heavy machinery
- Mining equipment
- Anywhere that can be described as “severe service”
It may be desired when toughness and impact resistance are more critical than corrosion resistance, making it ideal for specialized hydraulic systems under stress.
What Are the Different Heat Treatment Processes for Various Steel Grades Used in Honed Tubes?
Are you optimizing the heat treatment for your steel? Different steels require different heat treatments to achieve the best mechanical properties.
- ST52 and E355: These steels are usually cold drawn and then stress relieved to reduce internal stresses and improve their mechanical properties and assure accurate dimensions.
- SAE 4140: Typically, SAE 4140 undergoes quenching and tempering. During quenching, the steel is heated to around 850°C and then rapidly cooled to harden it. Tempering at 550°C reduces brittleness and increases toughness, ensuring it can withstand high-pressure and high-stress environments.
The heat treatment process plays a vital role in improving the strength, hardness, and durability of hydraulic honed cylinder tubes, ensuring they can perform consistently in challenging applications.

How Does the Cost of SAE 1020 Honed Tubes Compare to Other Materials Like ST52 and E355?
Optimizing your budget. Where SAE 1020 might save you money and where it won’t.
SAE 1020 being a low carbon steel is cheaper than the other two yet has a fairly high tensile strength and good wear resistance. While 1020 is used in less demanding applications, it makes sense if the application is more budget driven due to the lower up-front costs. However, be careful when selecting 1020, as saving in the short term may harm you in the long run with increased maintenance cost.
While E355 and ST52 are more expensive, their higher strength, durability, and solid resistance to wear and corrosion make them perfect for long-term applications.
Unfortunately, as we all know, things that are a bit more expensive tend to be a bit better.
Conclusion
In conclusion, hydraulic honed cylinder tubes are typically made from a variety of materials, including carbon steels like ST52, SAE 4140, and SAE 1020, as well as stainless steels such as 304 and 316. Each material offers specific advantages, making it essential to choose the right one based on your application’s requirements for strength, durability, and cost-efficiency.
