ST52 /ST52.3 Honed cylinder tubes
ST52 honed cylinder tubes are precision tubes made from ST52 steel grade, following the DIN 2391 standard. ST52 is equivalent to ST52.3, and these tubes are typically referred to as cold-drawn seamless honed tubes according to DIN 2391/ST52-BKS. The “BKS” designation indicates that the honed tubing undergo a stress-relieved heat treatment process to enhance their durability and performance. Here below is the detailed specification for ST52 /ST52.3 steel.
| Grade | Chemistry | % | Yield | Tensile | Elongation | Typical Hardness |
|---|---|---|---|---|---|---|
| min. Mpa | min. Mpa | % in 2″ section | Min | |||
| ST52.3 | Carbon | 0.140 – 0.180 | 420 | 580 | 15 | B-80 |
| Si | 0.150 – 0.300 | |||||
| Mn | 1.200 – 1.400 | |||||

| S | 0.010 max |
E355 Honed tube /S355 honed tubing
E355 honed tubes are precision cylinder tubes manufactured from E355 steel grade, complying with the EN 10305-1 standard. E355 steel is equivalent to ST52 / ST52.3. These honed tubes are typically referred to as cold-drawn seamless honed tubes per EN 10305-1 / E355 +SR, where “+SR” indicates the stress-relieved heat treatment applied to enhance the tubes’ strength and performance.
Here below is the specification of the steel E355.
| Grade | Chemistry | % | Yield | Tensile | Elongation | Typical Hardness |
|---|---|---|---|---|---|---|
| min. Mpa | min. Mpa | % in 2″ section | Min | |||
| E355 | Carbon | 0.140 – 0.180 | 420 | 580 | 15 | B-80 |
| Si | 0.150 – 0.300 | |||||
| Mn | 1.200 – 1.400 | |||||
| P | 0.020 max | |||||
| S | 0.010 max |
Material ST52 /ST52.3 and E355 is also widely used to produce hard chrome plated hollow bars, which is also known as chrome plated OD tubes.
SAE 1020 Honed tube
SAE 1020 cylinder tubes are precision honed tubes made from SAE 1020 steel, which is equivalent to the Chinese steel grade 20#. SAE 1020 is a carbon steel known for its low cost, making it a cost-effective alternative to higher-strength steels like ST52. While SAE 1020 honed tubes are less expensive, they still offer reliable performance in a wide range of applications. These tubes are commonly used in industries where moderate strength and durability are sufficient, such as in low to medium-pressure hydraulic systems, automotive components, and other general engineering applications. Despite its lower cost, SAE 1020 provides good machinability and can be easily fabricated, making it a versatile choice for many industrial uses.
| Grade | Chemistry | % | Yield | Tensile | Elongation | Typical Hardness |
|---|---|---|---|---|---|---|
| Min. Mpa | Min. Mpa | % in 2″ section | Min | |||
| 1020 | Carbon | 0.150 – 0.200 | 375 | 485 | 15 | B-75 |

| S | 0.035 Max |
SAE 4140 honed tube
SAE 4140 honed tubes are cold drawn seamless honed tubes made of alloy steel grade SAE4140. 4140 honed hydraulic cylinder barrel tubes usually are used for applications under high pressure & heavy duty. As the tensile strength and yield strength of SAE 4140 is very high. Steel 4140 is equal to German steel grade of 42CrMo.
Below is the chemical composition of 4140 material.
| SAE 4140 /42CrMo | C% | Si% | Mn% | P% | S% | Cr% | Mo% |
| Min | 0.36 | 0.1 | 0.65 | 0.75 | 0.15 | ||
| Max | 0.44 | 0.4 | 1.1 | 0.04 | 0.04 | 1.2 | 0.35 |
Here below is the mechanical properties of SAE 4140.
| 4140 / 42CrMo | Yield strength | Tensile Strength | Elongation | Hardness HB |
| Min | 800 Mpa /115K psi | 900 Mpa /130K psi | 20% | 270 HB |
Steel 4140 / 42CrMo is also an idea material for manufacturing Chrome Plated Bar. Benefit for its high yield strength and tensile strength, 4140 chrome plated bar is usually used for applications where high strength is required.
27SiMn honed tubing
27SiMn steel also can be used to produce honed tubing, though not as popular as ST52.3 /E355, this material of honed tubing is idea for some special applications.
27SiMn steel material chemical composition: C: 0.24-0.32%, Si: 1.10-1.40%, Mn: 1.10-1.40%.
27SiMn steel material mechanical properties: tensile strength min. 980 MPa; yield strength: min. 835 MPa; elongation after fracture: 12%; reduction of area: 40%; impact energy: 39J.
27SiMn honed tubes are also used for high strength applications.
20MnV6 honed tubes
20MnV6 steel also can be used to manufacture hydraulic cylinder honed tubes. It is a carbon-manganese steel micro alloyed with vanadium, generally supplied in the black hot rolled condition with a typical tensile strength range of 600 – 790 Mpa and a high typical yield strength range of 440 – 650 Mpa. 20MnV6 honed cylinder tubes usually is used for Super high strength applications.
